When you want your music to sound its best, you just can't beat a good two-channel stereo. Connect your speakers to the Harman Kardon HK 3770 and this powerful receiver will bring those tunes to life the way they were meant to be heard. Whether you're listening to songs from a CD, turntable, networked computer, or a smartphone, this receiver has the connectivity to play them and the brawn to bring out their dynamics and detail. Digital inputs even allow it to improve the sound of TVs and streaming media players like Apple TV®, too. With so much versatility, this receiver goes above and beyond old-school models, while retaining classic Harman Kardon sound.
Harman Kardon has been working to make their receivers more energy efficient without compromising sound quality. The HK 3770 represents the fruits of their labor. It utilizes Harman Kardon's GreenEdge™ technology. Rather than redesigning the high-current Class AB amplification stage, this receiver features a new digital power supply. Unlike conventional analog power supplies, this new digital design uses less energy, fewer raw materials, and produces less heat. The result is a lightweight, efficient, eco-friendly receiver that delivers the same sonic benefits we've come to expect from this audio innovator.
The HK 3770 offers two ways to stream music wirelessly. Built-in Bluetooth lets you stream tunes from a smartphone, tablet, and even some computers without a home network. It's the easiest way to enjoy your digital music collection with room-filling sound. If you have a large digital collection stored on a networked computer or NAS, the HK 3770 is Internet-ready. Connect it to your network router and stream music from your computer over your wireless home network. You can also listen to thousands of free Internet radio streams from stations around the world, going far beyond the reach of the built-in AM/FM tuner. Download the free Harman Kardon remote app to your iOS® or Android™ device and use it to control the receiver. App control requires a wireless home network and a wired connection between your receiver and your network router.
The USB port on the HK 3770's front panel lets you plug in your iPhone®, iPod®, or iPad® to listen to music. This connection bypasses the device's digital-to-analog converters in favor of the receiver's high-performance DACs. That means you'll get smoother sound with more detail than your iPhone can deliver on its own. You can also use the receiver's remote to control playback with connected Apple® devices. The USB port is also great for playing digital music files on thumb drives by popping them into the USB port.

Average Customer Review(s):
Great unit, pairs well with my Klipsch standing speakers
So far, I'm very happy with this HK receiver. I needed a high wattage unit to run my old KLH 16 ohm speakers and this did the trick. Looks very nice and sounds excellent. It will get warm quickly, so plan your cabinet very carefully. I have mine in an old audio cabinet that has flip up top for a phono so mine gets plenty of airflow. At first I felt the remote wasn't very user friendly. Once I devoted time to read and learn, I really liked how inputs are assignable and now am quite happy
Pros: Price, appearance, high output
Cons: Gets warm quickly, remote a bit complicated at first
A decent Owners Manual would help. Labeling on the front of the receiver, and on the remote, needs to be in a larger font (3 point (?) is a little small). Sounds good.
Finally upgraded to a modern receiver from 38 year old equipment. This unit doesn't have all the tone control my old unit has but found that with the quality of this unit and matched up with new Polk RTiA7's I don't seem to miss that. Being able to just sit down and tap on my phone and start listening is awesome. I am a techno illiterate but am excited about all the modern functions this receiver has. Apart from that it is much lighter than the old unit it replaced and runs so much cooler after extended playing. Took me a long time to give up the vintage but so happy I did with this receiver. I don't see how anyone would be disappointed.
Pros: Love the power and technology. Great choice for me and fits well with other components I have.
Cons: Would like to have more record out connections on the back but since there are other stereos in the home it is not a deal breaker.
It's the perfect balance of power, quality, connectivity, and value. Great sound!
Harman/Kardon is a household name, when it comes to High Quality audio. The 3770 preserves that HK sound; But also is integrated with today's technology. The 3770 has gobs of power!At the pinnacle of it's power; that HK sound is beautiful! Not distorted, but beautiful! This mainly due to it's high current design. I've heard High End receivers, of which cost 5 times the price of the 3770. I'll say this, the 3770 can hold it's own, in comparison!
Pros: That Harman/Kardon Sound Gobs of Power No distortion Really nice looking
Cons: In the future; it needs the ability to play FLAC audio.
I love this unit! It is replacing a retro Sansui that I thought could never be. Sound is great. Features are more than I could ask for. Has Bluetooth and streaming features. Love the fact that it offers a sub-woofer out, even though it's a two channel amp in case you desire a little extra bass.
Pros: Too many to list. See narrative.
Sonically, this is well worth the money. The sound is clean and smooth... and not too bright. Very well done.... especially for the cost. This would have been a 5 star if not for three things.... 1) there is no complete owners manual included, there's a safety guide and a quick start guide, but no full manual. To get one... you need to sign up at Harmon Kardon so their marketing department can harvest your information. I sent a request for a manual, reluctantly giving them an email... no response. There's that. 2) the channel/function indicator is easy to read... but the other controls on the front are very hard to see. 3) the controls feel cheap and plastic. Those are all secondary to the performance of the amp... but still. Small things, especially a manual... or easy access to a manual would have been great!
this receiver sounds super great.it has plenty of power. it does every thing that i want it to do.
Cons: i have not found any cons yet.
This is a great receiver/tuner! I'm replacing my old system that I love but none of the remotes work and it is just time to. This unit produces some incredible sound without an amplifier and I certainly had my reservation turning lose of it. I have a rare set of JBL's that I will never part with and this unit has really put them to the test. The sound is crisp and clear yet can produce a surprising level of bass and range. I'm somewhat old school and don't want all that surround sound, just give me a pure good quality system with two speakers and I'm happy. I chose Harmon Kardon after listening to it in a studio and I also had a system that came in one of my vehicles. They so a great job and I couldn't be happier with my purchase!
I like it so far. There is a learning curve with all of the features and functions.
Pros: Many and flexible input selections
Cons: Tiny dark buttons on the remote should come with a lighted magnifier.
Easy to set up, versatile, and plenty of power for the speakers.
Love the bluetooth connections and the power drives our tower speakers perfectly! Options for tone settings are great, too.
Just hooked it up to my trusty old Signet speakers and tuned to the classic rock station. Good FM reception without unfurling the antenna. Nice and clear and loud. Features intuitive. Looks good. Was going to piggy back this off of my old trusty old Kenwood receiver to drive a third set of speakers. But have changed my mind and will use this HK as my primary to run the first and second set of speakers and give the Kenwood the third set, and deserve light duty.
Pros: Power. Clarity. Ease of use. Can run either set of two sets of speakers, or both sets at once. Lots of interface options in case I ever jump into the 21st century.
Cons: Gotta go. Stones just came on and I need to concentrate.
very good deal
Great sound, should come with a manual
Good sound, could use a bass enhancement circuit. Very capable in the upper frequencies.
Greate sound. I'm still learning "what to do" . Use of the HK Sound functions very well and makes switching between functions "painless" with little or no volume difference.
Pros: Hookup was fast and took little/no serious thinking. Sound quality very good.
Cons: instructions/manual needs more thought and was very sketchy in parts. Especially on hookups. Too much reliance of the use of remote to switch functions. For this reason I rated it as a 4 star recever.
I read many reviews for this receiver that proved very helpful in my decision to purchase this model. I've found this unit to be just what I wanted at a great price and the instruction manuel thorough. I had questions about hooking up my turntable and called Crutchfield for advise. I spoke with Scot and he answered my questions quickly and was extremely patient, which was important for an electronic illiterate person such as myself!!! Thanks again!!!
Pros: Very easy to hook up and operate
Old guy looking for music the way we played it in the 1960's. Easy to set up, sound clear, and accurate. Have not used my SP 9000 Sansui speakers for years you should hear those 8 inch horns, 14 inch base and twin twitters. Amazing. Rock on old school!
Pros: Fast delivery, good price. Plug it in, hook up speakers, adjust base and treble and start listening.
Cons: Should have done this years ago.
Very happy with this receiver but wish it had some HDMI inputs.
At 120 watts/channel, a nice powerful system. Front panel though could have been a bit easier to read but the illuminated volume control is quite a novelty. The owner's manual needs to be more informational. Pretty easy to operate.
Pros: Great sound quality and overall appearance.
Cons: Manual incomplete.
The 3770 has much more power than I expected. It is running 4 JBL 702's and a pair of Yamaha 5-1/4" outdoor speakers with ease.
Pros: Great price for what you get. Very clear and powerful. Nice modern look.
Cons: Manual is worthless... But it's not too difficult to navigate.
First day listening to the HK 3770 and all I can say is wow! It sounds great through my Pioneer SP-FS52 speakers when compared to the Yamaha Receiver the HK 3770 replaced. Excellent bass and midrange, really nice "punch" even with lower volumes, you can tell this is a powerful amp, no doubt. Easy setup and intuitive controls. I love the way it looks and the volume knob lighting is very cool, especially at night. The display lettering is large enough that I can read it from across the room. I did a lot of research on the HK 3770 before buying one. I heard some complaints that it was "light" and not well built. Sure it weights less because it's designed and manufactured for Green Technology. Uses less materials and energy but still performs outstanding. Great purchase.
Pros: Sounds better than more expensive receiver s.
Cons: None so far.
Just what I expected. Easy set-up, great sound, and enough power to drive Cerwin Vega SL - 15's. I would recommend this affordable amp to audiophiles on a budget.
Pros: Great sound, enough power, and easy operation
Cons: Haven't discovered any yet
Very hard to find a stereo receiver as good as the best in their heyday of the 1970s and 1980s. Harmon-Kardon made at least one of great receivers -- the HK 730. I bought one new in 1974 and still own it. Here is a 2017 audio expert's review my old receiver: http://www.highfidelityreview.com/harman-kardon-730-receiver.html. The HK 3770 looks completely different. But the sound is close to the awesome sound of the HK 730 -- better than anything I've heard on sets costing up to $2,000. One reason -- HK730 has Class A/B electrics, same as the HK 730. Sub $2,000 receivers and integrated amp are almost always Class D. Class D is more energy efficient. But A/B electrics produce a richer sound, in my opinion. Kudos to HK for bringing A/B electrics back to listeners that can't afford to spend $2,000 on a receiver or integrated amp. The HK 3770 not a retro receiver. It taps Internet radio stations, has a remote control, a sub-out, and digital signal in-and-and out receptacles, in addition to five analog RCA connectors. It also has phono input and phono amp, just like my HK 730. Vinyl and remastered classic rock and jazz on CD sound super on the HK 3770. That's all I've listened to since setting it up three days ago. I look forward to playing Internet radio through my stereo system for the first time. For the price, the HK 3770 is a sensational deal
Pros: Has the power to drive my PSB tower speakers and fill my large living room with excellent sound and a good soundstage. For the price, nothing comes close to this.
Cons: no volume balance control.
All I needed was a 2 channel stereo and it has exceeded my expectations
The HK 3770 makes the sound and music crisp with my old Bose 4.2 speakers. I like the way my vinyl sounds through receiver. BUT...Being 58 and needing "cheaters" to see most things especially fine print, I need to be remember the settings on the front display and remote for the selection. Or ask my son teach me how to make selections on the remote. So tiny...
The power and sound is great. However, the user interface is clunky, sometimes you have to wait a half a second before the unit will respond to button pushes, like moving between sources. It's got 5 analog inputs, but every time I want to use one I can't remember how to do it on the remote or the front panel, it is not intuitive at all. I was surprised there was no "loudness" feature like every other HK amp I've owned. I'm a diehard HK fan, but I'm really disappointed with the user interface of this unit.
Pros: Power, sound
Cons: User interface is really disappointing
i am very satisfie about my products. Thank you so much !
Excellent product. This was an upgrade for me from the HK 3370, and I'm very happy with the quality, and the sound, of the HK 3770. The bluetooth works well, and the internet connectivity is a real plus. There is a good selection of world internet radio stations. The sound is exactly what one would expect from Harman Kardon. This is my third HK receiver/amp, and I have loved every one of them. The upgrade from 85w per channel (HK 3370) to 120w per channel has made a real difference in clarity. I play this through a pair of Clements 308 di's, and the sound quality is fantastic, even at very low levels. The only thing I would change would be the control over the bass and treble levels. The HK 3770 has only digital controls, and only in increments of 2 (2,4,6,8,10). I would prefer to have more manual control of these levels, but that is my own personal preference. Overall, an outstanding product.
Pros: great quality sound bluetooth internet connectivity optical connections
Cons: only digital (vs. manual) bass/treble controls
Just okay. when I get something, i like to use it. couldn't. have to go to website to downtown manual and there website isn't easy to use
Good, simple receiver that I bought to anchor a stand-alone stereo to listen to vinyl. Only negative is the huge volume difference between the analog inputs and the phono input.
NOT TO HAPPY WITH THE PRODUCT MOSTLY BECAUSE i CANNOT MODIFY SOUNDS AS MY PRIOR EQUIPMENT, ALSO THE MFG BOOKLET DOES NOT CLEARLY EXPLAIN THE CONTROLS ON THE SYSTEM
the receiver is powerful and as advertised. smooth as buttah. Crutchfield tech support and customer support are outstanding!!!!
Pros: remote control, many inputs, many functionalities.
This is a great sounding receiver for the price, but not if you desire complete control via an app on your phone or iPad. There is no wifi built in, so you need a hard wired connection for Internet radio. There is an auto off feature built into the receiver that can not be turned off. So, if you want to hide this unit and it turns itself off, then you must physically turn the unit on manually, you can not turn it back on remotely. The app does not give you any feedback regarding what you are listening too. If you are adding this to a single home entertainment system, no worries. If you are adding this to a whole home system, look elsewhere. I switched mine out to the Onkyo at the same price, but with built in Wifi and a much better app. I hope this helps you to choice wisely.
Pros: Great sound, competitive pricing
Cons: No wifi, turns itself off after a certain time, horrible app for remote access
Good Receiver........Purchased the Black Series 2 Towers as well as the PSW 111. Still breaking in however very satisfied to date. This is my first experience with Crutchfield (Highly Recommended).
Looks and sounds great. Easily compatible with my turn table, and iTunes.
It sounds okay but distorts with most music around -10dB. The music chosen is Porcupine Tree and Diana Krall - both very well recorded. Playing into JBL Studio speakers, which are pretty decent. It totally loses it around basenotes. The manual is a total joke and the android app for it does not work at all.
Pros: Not crazy expensive but I got it on the HK company store, since I worked for them.
Cons: Sound it not very good, manual is a joke, app does not work.
All functions work nicely: Bluetooth with phone, TV, phono, tuner stations. Haven't figured network yet.
Pros: Tons of power. Sub out.
Cons: Now I want better speakers.
Crutchfield set me up with a cart that previously included the Yamaha R-N301 receiver. I wasn't all that blown away by the sound and the receiver didn't even have a subwoofer out function. Once that was sorted all out, this receiver became one of my options for needed 1) optical out, and 2) sub function. This receiver sounds so much better than the Yamaha and with my sub now working properly, it really does please me. I can't speak much for the functions on this as my TV is hooked up with AppleTV, GoogleCast, and other smart features so everything is routed from my TV to my receiver.
Pros: Great clean sound, nice power, subwoofer function, optical connections, Bluetooth, etc.
Cons: None that I can think of. I just really dislike most remotes that come with receivers and this one is no different.
I needed a replacement receiver to power speakers in 3 different rooms, not AV, and this HK 3770 fit the bill perfectly! Sounds great with all 3 sets of Bose speakers, indoors and out, lots of power. The USB port on the front is a nice feature to plug in the iPod, as well. The receiver came in 2 days, simple to set up, great support from Crutchfield!
Pros: Lots of power for my needs, USB port
I received my stereo with a few holes in outer box. Thanks for double packing because no damage to unit. Went on-line using google to get manual docs on stereo (failed to get them from HK website). Basically I learned as I flipped through the panels how to set up the unit. Somewhat simple especially if you are not computer illiterate (it would be great for a good manual to show some of the panel options). Connected to my network using network function downloading music from computer, also vtuner connected no problem. Finally I can listen to contemporary jazz; have no local station. Stereo works and sounds great with no distortion or noise. Sad part is now I got to buy speakers that handle this stereo output- I got a feeling mine won't handle it. Need a better antenna to pull in FM stations. So far I really like this unit performance wise and like to thank CJ for helping me select it. Very happy !! Great service from Crutchfield and I'll be looking for other things in the future.
Pros: Clean power & no distortion. Somewhat easy to set up software-wise.
Cons: Lack of a good manual. Panel buttons are small & hard to discern.
The Harmon Kardon HK3770 is a replacement to a HK490i that performed well for over 30 years. It burned out after a LOUD rock session. With only 30 watts per channel, the old receiver caused a 50 pound loudspeaker to walk off its pedestal!! The new receiver is rated at 120 watts per channel. Walking a speaker off the pedestal became really easy, I added a rubber sheet under each speaker to prevent future incidents. Also nice is the front USB port allowing an iPad to be used. This receiver is spoiling us with its clean power, multiple input features. I now have ordered a powered sub-woofer to complete the package.
Pros: High current chassis design pours a lot of power into loudspeakers. Clean, clear power. Digital input for CD player makes much improved playback that sounds better than my old HK.
Replaced a Harman Kardon Hk3400 with the HK3770, with Bose Acoustimas 5 speakers. The 120 watts makes the Bose sound great, the price was reasonable. I don't regret the purchase a bit, great receiver. I was amazed how fast Crutchfield had this purchase on my door step, definitely use them again.
Pros: Love the Bluetooth feature, remote is good, great sound
Cons: The HK Remote app sucks, have not figured out how to get it to work yet.
Sounds good easy to operate. I use the receiver to drive speakers in other rooms.
Pros: Easy hook up good sound ample power
The amp has yet to fail to meet my expectations. I'm taking time to learn all the functions and capabilities.
Pros: Clean power. Ease of operation. Dollar for dollar, worth the money thus far.
Cons: Have yet to find a con.
This receiver replaced a 30yr old Hafler system. It sounds nearly as good takes up less space and with the digital operation and remote is easy enough to use. The combination of analog component inputs with the modern digital, blue tooth connections is nice to have.
Pros: Digital, plus analog connections. Good sound
Cons: lacks a tone control
The sound quality and lack of distortion is truly amazing. I listen to classical and wanted an in-the-same-room experience when listening to chamber or piano. Great for steaming services, because the DAC conversion is handled by superior HK electronics, not by your smart device. Service at Crutchfield is equally superb.
Pros: sound quality you'd find in $2000 receiver but at 25% of the price
This is a fine piece of electronics.
Pros: The phono input is great! Not seen on many other units.
Cons: No users manual included and can't seem to retrieve it on the internet. It is kind of like "learn as you fumble through it". No real guide as to how to set up the remote to add other equipment like tape decks and CD players.
So many functions and I really just want it for a few but I was taken by the 120 watts per channel which put this out in front within the price range. The sound has been perfect so far and the bluetooth connectivity works so easily and well. The remote control is very nice but I have to say that the front panel controls are neither useless if you don't have some terrific lighting on them. It's a flat front panel, all black with little discerning one button from the other. Fortunately the remote control takes care of it all very easily. I'm only using this for my turntable so far so I've hardly taken full advantage of it but the radio seems to work great and so much more.
Pros: 120 watts per channel, great sound, Bluetooth, internet, Wi-Fi connectivity, nice receiver for radio and amp for turntable, very useful remote control
Cons: Not particularly attractive looking, hard to discern the button controls on the front panel, volume knob is a little touchy to get the hang of
I purchased this receiver to replace a Sony. What I really like is that this receiver is built to be smooth--the power and clean sound, even at low levels, is great. I also really appreciate, unlike some of the "simpler" receivers is that is has multiple digital inputs. I am using it to power my AR TSW510's and they sound like new. Great set up with Apple TV and iTunes. The receiver also provides great sound across the music spectrum--rock, jazz, classical. Am looking forward to years of wonderful sound.
Pros: Price, power, connectivity.
Cons: None at present.
Great value for the price. Easy to set up and use. This receiver does everything it was advertised to do. Very happy with my purchase.
Pros: Easy set up.
Cons: Manual leaves a lot to be desired
I've only had the Harmon Kardon 3770 Receiver/Integrated Amplifier for about a week now. So far, I've used it only w/ CD's played via my Sony DVD player via the optical output connected to the 3770's optical input. The 3770 drives my pair of Gallo Acoustics reference 3.1 speakers just fine w/ plenty of volume in our medium-sized living room/dining room (open floor plan). The set-up for the CD/DVD player and stereo speakers was easy. I'm just now trying to enable the internet radio features (e.g. vTuner) by connecting it to our home network. So far I have been unsuccessful, despite the 3770 displaying a confirmation message on LED display that I successfully connected to my home network. Compounding my challenge is the 3770's User Manual, which has only basic instructions on connecting to your home network and accessing internet radio content via vTuner. The troubleshooting section of the manual provides only the most basic troubleshooting guidance and is mute on troubleshooting connecting to a home network and problems using vTuner.
Pros: Easy set-up for CD source component. Plenty of power to drive most speakers. Very good sound.
Cons: Unit has Bluetooth connectivity but no wifi. User Manual is very far from comprehensive. I'm currently struggling to set up access internet radio via the unit's vTuner feature. If I'm able to resolve this I'll either update this review or submit a new one.
I bought it for the Bluetooth feature, it works great!!!
Purchased this newer HK too replace an much older HK to drive my new Klipsch RP-280s Right out of the box it it would not work in CD mode used other mode I can't explain . The bass + treble controls only worked in certain modes. The users manual recived with unit is useless! The one printed off web sight was No better. I truly expected A world class receiver, to my disappointment it was not
Pros: Its small and light
Cons: It didn't Work
Harman Kardon has a winner with this one. Sound quality of this receiver is stellar, not to mention all of the bells and whistles. Coupled with my new Klipsch Reference RF-52 II speakers, I now have ultimate stereo I've been waiting for.
Pros: Performance & sound quality are awesome, just what I was looking for
Cons: These are minor, however, you will need to download the PDF manual from HK as the one the comes with it is worthless. Setting up the internet options is a bit tricky, have your tech savvy kids or friends help ya.
I was looking for a receiver with digital, wireless, and phono connectivity. I couldn't be happier with the 3770. This receiver has worked flawlessly for me so far. I have read reviews that discredit the bluetooth function because of it's limited range so it is worth mentioning that Bluetooth technology does not have a very far range in any device. I find that as long as my phone is in the same room as the receiver there are no pauses in playback. I use an Apple TV connected via a toslink cable for wireless listening with Apple Airplay. Airplay is sonically superior to Bluetooth and it's range is only limited to the size of your wi fi network. I can listen wirelessly with Airplay from any room in my house with no playback issues whatsoever. My favorite part of this receiver is the phono stage. I have a Pro-Ject Debut Carbon hooked up and the rig sounds remarkably robust yet detailed at the same time. In fact the sound on this receiver sounds great from any of it's many connections. I wasn't expecting to, but I've even been listening to the VTuner radio. I was pleasantly surprised by the sound quality of this internet radio. I will hang on to this gem for a long time.
This stereo receiver/amp With DAC , is simply the best for the price. they easily power my new Focal Chorus 726's and a sub woof......Has many backside ports and can be used in many ways.
Pros: Efficiency of the price..
Cons: Ummm...........I guess,....it wasn't Free.
Great system for running backyard speakers. Not equipped for surround but not needed in outdoor environment for my setup.
Pros: clean power
Cons: only one zone
This HK product is superb! I previously bought the HK 3770, and came back to buy this one with Bluetooth. The Bluetooth makes it! HK: sound tuner! Highly recommended.
OK so lets get serious! The HK3770 is a fantastic reciever. CD player I also purchased with this amp. The Onko C-7030, very smooth affordable player. The Cd is connected with a optical wire for best possible fidelity. The speakers are JBL 4312C control monitors, old school maybe but they sound great.They are professional studio speakers. They are tiled up on speakers stands & no rugs on the floor. I am a musician & have recorded my records, I just got my butt kicked! Lets talk about what I played to sample this, first classical recordings on the light side Mitsuko Uchida, Mosart, Emerson String Quartet Medelssohn String Quartets WOW just beautiful. Then Kevyn Lettau a jazz Cd, A reissue a super 24 bit XRCD fron JVC this was better than amazing. How bout a rock record the new remix & mast from Steve Wilson of Jethro Tulls Aqualung. Man I was crying This new mix (Just like the original as not to alianate the listiner)has no compression so is like if your the studio oh my. Then the new master of The Rolling Stones Sticky Fingers Holy Crap Then James Taylor new record Before This World. Man oh man all of this sounded just great I am happy camper. The radio also is important to me so I'm very good with the FM & the AM section. I also do an I pod classic for parties not as good because its MP3's but I get that. this amp has many other features ,Internet, Bluetooth (my son will stream his phone. The only thing is the manual you have to figure things out for your self. GREAT AMP !!
Pros: Sounds great lots of power loud or soft The amp itself looks great. I also thought that the price is right for the quality.
Cons: Manual does not tell you how to do things except to plug in.
Excellent product; sleek design, great stereo receiver
Pros: Put's out great sound for surround sound stereo system throughout the house
Cons: A bit over pricey
If you like Stereo Sound, You'll love this unit!
Pros: Excellent Stereo Sound with beautiful separation. Overall audio sound is fantastic at All volume levels!
Cons: Needs more setup/operation information. Cannot override the 8 hour auto shutoff.
I've had this receiver for almost 1 1/2 years. I told the Crutchfield sales rep who recommended this receiver that my criteria was a receiver that produced clear sound and could "play music" from my laptop music library. I had lots of problems the first week and could find NO helpful information on the HK website and certainly not from the almost worthless documentation that came with the receiver. The Crutchfield support team was patient and helpful, but because HK had/has so little documentation, their ability to help was limited. When I bought this I was under the impression that I could play music wirelessly. And I was able to do that, except that I had no control over what music it played. So, in order to play the music I wanted to play I used the bluetooth function exclusively. When I'd had the receiver about 6-8 months, the bluetooth became sketchy (that is, the music would skip--as in disappear--for seconds to minutes several times an hour) unless my laptop was right next to it as opposed to 10 feet away where I usually have it. I have since begun playing my music via a ZVOX (bluetooth) and have had no problem, so I must conclude it is the receiver not the laptop. So not only did I blow my money on a receiver, I also blew what I paid for the speakers.
Pros: When it worked, it was fine.
Cons: 1. After 6-8 months, bluetooth stopped working consistently (music skipped for up to a minute several times per hour). 2. Total lack of meaningful documentation.
So far, so good! I bought this to replace a cheaper receiver that I had my turntable hooked up to because I was moving the old receiver out to the garage. I think this one sounds much better than my old setup. I really love how this one has bluetooth integrated into the unit. The only criticism that I can think of is that the product manual is very bare bones. Some of the features and settings aren't really intuitive so it takes some time to figure out how to configure everything.
Pros: Bluetooth, sounds great, looks great
Cons: Documentation lacking detail - need to figure out how to use some of the features or configure some of the settings.
Easy setup, crisp clean sound with my Klipsch La Scalas.
Pros: Clean design, easy setup nice remote. Love the Bluetooth
Cons: Presets would be nice on the panel. Better included manual would help. I have a DbX box that I need to make part of the tape circuit. Will figure it out eventually
I provided the top rating on the equipment, but some things that were not desirable. In the box, was only a "starter" user guide that was far from being what is needed to use the equipment, and no mention of how to get a real user manual, sol had to call Harmon Kardon to get a user manual sent by email in PDF format. The sheer power prduced is good, but the FM tuner does not pick up stations I think it should. Only one output on the receiver, labeled "record", but found out it can be used as a normal output for other devices. Do not care for the "stereo" button which has to be ;pushed frequently to get the remote to operate properly to control the receiver. Use it to drive 2 Klipsch RF-82ll floor standing enclosures and it does the job very well.
Pros: good power
Cons: Manufacturer could do a better job providing a good user manual, either in hard copy or a disc.
Didn't have the space for all that movie experience stuff.....just a plain receiver and speakers that would fit in the confines of a California Closet shelf setup... the HK 3770 sounds great...a previous reviewer was right.....lose that remote and you're toast..and the buttons on the receiver and remote are not intuitive...and you have to go to the HK website to get the manual....these things should have everything you need to know in the box..(oops, just hinted that I'm old)...paired it with a DT Pro Monitor 800 based on the Crutchfield rep recommendation due to size limitation of where in California Closet these had to go...and a Infinity Primus PS 38 (the only subwoofer that would fit in the largest cubby hole of the California Closet....and it sounds great !!!! Jazz, Classical, Latin...it all sounds great...
Pros: Sounds great....
Cons: Dependence on a remote that is not intuitive....buttons on the receiver are not intuitive...have to download manual from website...
This receiver sounds and looks awesome. It makes work a pleasure because I can enjoy all the great sounding music.
Pros: Fast blue tooth connection.
I use this to drive several sets of speakers including ceiling mounts in the great room, outdoor by the pool, and in the garage. I'm only using stereo and Bluetooth with my Apple devices at this time. Everything works great. The product arrived as promised and I have been very satisfied with it's performance.
Pros: Easy to use, looks good, great performance.
Outstanding Product all is good
Pros: sounds great easy to use!!
Very nice receiver, is very quiet and clear sounding. Pays phono vinyl with great clarity. Have a dvd player and cd changer plugged in also. Am very impressed with the unit.The component buttons on the face are a little small and hard to read, so the remote comes in real handy.Overall very nice piece.
Pros: Sound is very nice. Have a pair of Bose 301 and a pair of Bowers Wilkins with a Yamaha subwoofer plugged in . Handles power nicely with plenty of volume to spare.
Cons: The usb section does not shuffle the whole flash drive. Will only do one file at a time. That is my only peeve.
Very impressed with the performance of the HK 3770. I think the sound is very clear and true with no noise. Not even close to breaking a sweat. A little disappointed with how it handles music on USB thumb drives. It does not advance to the next folder when the last song of the current completes. It does play the music off the thumb drive excellently though.
Pros: Great sound. No noise. Simple set up and use
Cons: Doesn't continue to the next folder when the last song completes in the current.
This receiver is amazing. Everything works great. The power to my Polk Audio speakers is amazing. The best part about this is the network radio stations and bluetooth. Once I hooked up my network cable I could listen stations around the world. There a lot of good genre stations to listen to. Whatever you want, you can find it. The other cool thing is the ease to hookup to my Iphone via BlueTooth. I was worried about the hassle of pairing the receiver and our iPhones. It did it all by itself. Too easy !!
I looked for a replacement for an old Kenwood Amp and tuner. Was amazed at how little is available for a basic Stereo system, that can handle inputs for phono, tape decks etc... This is the perfect match for "old Tech" and new with the option for Bluetooth, Network and Input for phone or Ipod. Distortion is non existent, so upgrading to some Klipsch speakers to go with it. Crutchfield CS was very knowledgeable and helpful in assisting me to choose this receiver. Ordering and delivery was absolutely hassle free.
Pros: Light weight, assume circuitry has changed drastically from the old heat sinks etc... Remote covers about everything. Just got it, so still learning.
Cons: Full operators manual had to be downloaded from HK. Manual that comes with unit is very brief, does not cover remote too well. Only con so far.
Does every thing as expected. Performs well with my vintage Polk SDA speakers and my pono player
Its been 25 years since I've purchased a preamp/amp set or receiver in this case - things have changed a great deal. This receiver has all the latest tech incorporated in it, and the sound matches the tech level - outstanding. Its not intuitive to use for the older crowd but once you spend the time understanding how things work, it has some great features / benefits.
Pros: Outstanding features, up to speed with related products (smart TV's, DVD/CD players) Plenty of power High quality appearance
Cons: Only compatible with Apple products - would like to see Anroid compatibility too No wireless option for connectivity / networking
The receiver is just what I wanted: a non-surround, simple machine. Too many other receivers had many more features than I would ever use. This plays the radio and all my bluetooth phones and pads. The look is very sharp, it is super simple to use, and it sounds great (most important).
I've had this HK receiver for about 3 weeks now. It was easy to set up with a CD player and the TV (stereo output.) It was easy to connect it to my home (wired) internet via ethernet cable and the Bluetooth connected quickly. Most importantly, it sounds good. As a couple of other reviewers have noted, there is one significant drawback that prevented me from giving it 5 Stars. The buttons on the receiver are very small and hard to see. Somewhat irritating is that the labels for the buttons are also small and hard to see. If you plan to put this in any sort of cabinet that would cast a shadow on the front of the unit, forget it, you won't be able to see what you are doing. You are basically completely dependent on the remote, which is, thankfully, laid out fairly well. As another reviewer mentioned, guard the remote with your life, because if you lose it or it breaks, you have a big problem.
Good clean sound with nice features such as blue tooth, phono input, sub woofer out put etc. Works well w our Bose speaker set up. Good separation
Pros: Clean sound, nice crisp base and clean clear treble. a lot better than what I expected from a 20-20,000 unit
Cons: Doesn't seem to have left-right balance, at least I haven't figured it out yet. A little scary that you have to have the remote to run it, my kids are good at losing them. More info from the mfg on function and use of control options would be helpful. Miss my EQ capabilty I had on our old system but the HK is pretty good with out it
I love this receiver. It brings old school power to modern devices with the Bluetooth capability. It brought my Boston Acoustic tower speakers to life! Sleek design and easy operations. I wanted this for my music, but our TV sounds great without surround sound.
Pros: Pure HK power and Bluetooth capability.
Cons: Little hard to see some of the function buttons on the face of the unit inside the entertainment center.
Using as a wt room radio
Pros: Nice sound, clear highs
Analog decoder for phono input, CD's, etc... plus new digital advantages. Bluetooth is a handy tool.
Pros: Terrific stereo separation
Cons: none, so far
Coming from a 2-channel dinosaur, this receiver rocks. Well balanced tone without any adjustments, Bluetooth works as advertised with an iPad, radio reception is great, and can satisfy the vinyl soul as well. Really don't need the sub with this machine; drives my Klipsch RF 82s smooth as a greasy goose on a hot rock. Thanks Crutchfield & HK!
Pros: See above
Cons: Zero zilch nada
So far, so good.
Great looking and sounding amplifier! Easy to set up and operation is simple and to the point. Though the unit weighed much less than I anticipated, the sound leaves nothing to desire. Paired this with two Polk RTi A7's and the highs and lows are extremely clear and the unit delivers plenty of punch.
This amp sounds great and has plenty of power to push our old Cerwin Vega speakers with 15" woofer, 8" mid and 3 tweeters. It gets way too loud before any perceivable distortion. One small gripe is the lack of tweakability: not much in the way of customizing EQ. There also aren't any different modes, like for movie or music settings. But, so far we are loving the sound anyway.
Pros: Great sound. Plenty of Power for large speakers. Looks good. Good price. All the inputs we needed. Bluetooth works great.
Cons: Lack of EQ control. Lack of sound presets for different sources.
Needed a receiver to run 4 speakers and work with my IPOD. Does everything I expected it to do. Detects IPOD at twice the speed of the $1200.00 receiver it replaced. Love it.
Pros: Simple config
I have this receiver paired with two infinity primus floor standing speakers and an infinity primus sub. I was primarily interested in a system for music so the 2.1 setup works for me. I am still amazed at the clarity and detail this amp reproduces even at high volumes. Plenty of options for inputs is nice, though I mostly use one Aux in from my computer. Bluetooth is a plus though and works very very easily. I mostly listen to electronic, metal, alt rock, and oldies, all of which sound great. Don't regret my purchase at all.
I have been enjoying this receiver about a week now. I am not completely tech savvy when it comes to things like networking a million devices but I can say that as far a bluetooth is concerned and and the basics of an old time analog receiver, I am very happy. I only have bluetooth devices and a couple hundred LPs which is what I use most. LPs sound great on this system. I don't have CDs but I am sure they would sound great too. I also use it for sound on my television, so I have great control and clarity when it comes to watching movies and such. Each input remembers it's own settings in regards to bass and treble which is also very cool. I do recommend this product to anyone who wants a great quality receiver but is not interested in having a big surround set up yet would like lots of new tech options. I plugged in my internet into the back of the unit from my router and now have many hundreds of digital radio channels from every corner of the world. There is much to say so I recommend looking at the specs and if you do not know a lot about networking, you may need to find a friend that does to help you out with sharing your computer files wirelessly with the receiver. Thanks.
Pros: Pros are the massive versitility and new technology while getting away from the surround sound thing and getting back to the basics of a STEREO two channel high powered receiver. For me a phono input is always one of the essenital requirements. I cannot imagine this unit being a dissapointment to anyone.
Cons: In regards to the cons of this unit, it is heavily dependant on the remote control. There is precious little you can do without the remote in fact. That includes adjusting bass, treble,and even balance, not to mention all the higher technologies that cannot be adjusted without the remote control. So, if you buy this unit, you will need to treat the remote with a lot of care as you are going to need it to work throughout the lifetime of the receiver.
I grew up with 2 channel stereo's. Raw power and everything was big. Old school meets new technology. Everything from the past, but better. This HK is simple to hook up, 15 minutes maybe. Simple to use and really kicks!! This is used for outdoor sound paired with NHT's, WOW!!
Pros: Plenty of power. Simple easy, out of the box music in 15 min or less.

High-Resolution 24-bit/192kHz DAC: This stereo receiver is equipped with a 24-bit/192-kHz DAC for excellent sound quality reproduction that is natural sounding.
Harman Volume: Harman volume is an advanced digital signal processing technology to control playback volume. It evens out the volume level on everything you watch, improving your listening experience. Once you choose the volume level, Harman Volume does the rest. It helps you avoid volume increases from commercials, volume differences when you change channels or switch sources, and brings out the dialog.
Analog Inputs/Output: The Harman/Kardon stereo receiver features five analog stereo RCA inputs to connect up to five audio components, and one stereo RCA record output to connect to a CD-recorder and other recording device. Included in the five analog inputs is a Phono input (MM) for vinyl playback.
Digital Inputs: The HK3770 receiver is equipped with two optical (toslink) digital inputs and one coaxial (RCA) digital input for connection of a TV or media streaming device.
Phono Input: In addition to the five analog inputs, the stereo receiver is fitted with a Phono input (MM) for vinyl playback.
A & B Speaker Terminals: This receiver features two sets of speaker outputs (A & B), each with binding-post terminals. You can independently turn on or off each pair of speakers, as well as play both pair of speakers. The speaker pairs are wired internally in parallel. These binding post terminals will accept bare wire (up to 10AWG), pin-connectors, and banana plugs (single or dual).
Subwoofer Output: The stereo receiver is equipped with a mono subwoofer output for connecting a powered subwoofer. The output is full-range, so you will need to connect a powered subwoofer with a built-in crossover.
Headphone Jack: There is a full-size (1/4") headphone jack on the front panel. When headphones are plugged in the speaker outputs are automatically muted.
Ethernet LAN Port: The H/K stereo receiver is fitted with a RJ-45 Ethernet (LAN) port to connect the receiver to your home network to access your DLNA music server or Internet Radio.
Internet Radio (from vTuner): You can also listen to Internet radio stations using the vTuner Internet Radio Station database service particularly customized for this unit, providing a database of numerous radio stations around the world. You can search for Internet Radio stations by Location, Genre, New, Popular, or Podcast. You can store up to 30 of your favorite stations.
DLNA Certified: The HK3770 is DLNA (Digital Living Network Alliance) 1.5 and Windows 7/8 compliant for audio networking. This means it's easier for you to access and enjoy digital music stored on your PC. Compatible music files include MP3 (32-320kbps; 8-48kHz) and WMA (5-192kbps; 8-48kHz). You can use your PC to play music content through your audio system, or use the H/K receiver to browse and play music files on computer's hard drive.

Front-Panel USB Port: This stereo receiver is equipped with a front-panel USB (type-A) port that allows you to enjoy playback of MP3 (32-320kbps; 8-48kHz) and WMA (5-192kbps; 8-48kHz) music files from a USB mass storage class memory device; such as select Android smartphones (Froyo/Gingerbread OS only), portable MP3 players, or USB thumbdrives (not compatible with USB HDDs). The USB device must be formatted in FAT or FAT32. Using the unit's front-panel display and included remote control, you can browse your stored music files on your connected USB memory device. USB portable audio devices that can be charged via USB will be charged when plugged into the network stereo receiver's USB port (5V/0.5A).
Note: This unit does not support AAC or Apple lossless files.
iPod/iPhone Direct: The USB (type-A) port on the front-panel provides convenient connection for your iPod/iPhone so you can listen to your stored music and music apps through the H/K stereo receiver. The iPod/iPhone USB digital connection means that the digital audio signal from your iPod/iPhone is transmitted directly to the system, minimizing noise interference and allowing use of the receiver's DAC, not the DAC in your iPod/iPhone. This results in more precise sound reproduction. You can choose to control your Apple device from its clickwheel/touchscreen or from the receiver.. Basic playback functions (such as Play/Pause, Previous/Next Track) can be controlled by the receiver's remote. Song/artist information on your iPod/iPhone will display on your connected the unit's front-panel display. Your iPod/iPhone's battery will be charged while connected to the receiver. Using the Lightning- or Dock-cable that came with your Apple device to connect directly to the H/K stereo receiver, iPod/iPhone compatibility is as follows (as of 9/25/2014):
|Apple Device||Generation||Tested Version||Media Type||Control Type||Display Type||Charge|
|Audio||Video||Remote||iPod/iPhone||Artist/Song Text||Track Info|
Note: Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset the unit and your iPod/iPhone to regain functionality. If this doesn't work, you may need to wait until a newer software update is available.

You'll be able to wirelessly stream stored music and music apps from your Bluetooth-enabled Apple device, Android smartphone/tablet, portable audio player, laptop, or PC to the H/K receiver. You will also be able to control basic playback functions (Play/Pause, Fast Forward/Rewind, Previous/Next Track) using the receiver's remote control. Advanced music operation will still need to be handled from your Bluetooth-enable device. There is no song/artist information display on the receiver's front-panel display. Continue to use your Bluetooth device's screen to view song/artist info.
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the H/K receiver.
Remote Control: The HK3770 comes with an IR remote control for wireless operation of the receiver and your connected USB or iPod device.
H/K Remote App: Downloading the free Harman/Kardon Remote app from the iTunes App store onto your Apple iOS (5.0+) device or from the Google Play Store onto your Android (2.2+) device lets you control the HK3770 receiver from your smartphone or tablet device. You'll also be able to control your Apple iOS or Android device's stored music from the Harman/Kardon Remote app.
IR Input/Output: There is one minijack (3.5mm) remote input and one minijack (3.5mm) remote output on the rear panel of this unit. If the receiver is placed behind a solid or smoked glass door, the obstruction may prevent the front panel IR sensor from receiving commands from the remote. If the unit is positioned so the front panel IR sensor cannot receive commands from the remote, an optional IR repeater system (sold separately) may be connected to the Remote IR In jack and positioned to accept commands from the remote. The Remote IR Out jack can be connected to the remote input jack of compatible equipment to relay commands to that equipment.
Trigger Output: This minijack (3.5mm) output sends a 12-volt DC turn-on signal to another component that accepts a 12-volt trigger, such as a CD player or powered subwoofer.

This receiver replaces a much older one that is no longer working very well. Since it will be the hub of my old-school component system, I didn't need a lot of digital bells and whistles. The Bluetooth feature is all I need to stream from an iPad or iPod. The 120-watts are the big selling point, as this unit will be in an open-floor plan kind of space with cathedral ceilings. I'll be able to hear this throughout my unit with one pair of speakers. [ Christine Apr 18, 2018 ]

Music is a significant part of my life (still have my 1st amp-Technics SU8077-now part of the garage system). 2 years ago my wife and I became disatisfied with the quality of audio (esp. the music) when watching movies. I have a good Bose speaker set up (Acoustimass-connected to a Sony receiver) that I felt was under utilized. So I called Crutchfield and expressed my desire to "feel" the music in movies, and also enjoy Five Finger Death Punch to Anugama. Looking forward to enjoying the music!! [ Steve Mar 15, 2017 ]

According to the owner's manual, the Harman Kardon HK 3770 receiver goes to standby mode automatically if the following occurs: --For digital sources (Optical/Coaxial), after remaining idle for 15 minutes --For analog sources (USB/FM/AM/Aux/Phono/DLNA/iPod/Bluetooth), after 8 hours with no user input (for example, adjusting volume, navigating through menu options and so on) There does not appear to be any way to turn that feature "off" either.

I have no idea what the upper limit is. My USB drive has about 5,000 MP3 files on it. Works great. [ Stuart Jul 01, 2017 ]
Nice idea. I do not know the Polk's power demands or efficiency. I am driving a pair of Sansui three way monitors, and a pair of two way speakers with no problem. Often both pair simultaneously. The amp feels like it is at least a real 100 or 150 wpc. [ STEPHEN W Apr 25, 2017 ]

This receiver has multiple analog input jacks. So long as you have an analog output source from your tv or dvr, it should work fine. However, there may be better choices for tv. I bought this unit specifically because I have built in speakers throughout my house, and only wanted stereo output. It has Bluetooth which allows me to stream music from my iPad. I recommend you call Crutchfield and tell them how you want to use the unit. They are very good at helping a person make the right selection. [ DANNY Feb 23, 2016 ]
I did not try directly. I did connect my Blu-Ray player using a digital cable and that works as expected for DCs, DVD/Blu-Rays, and streaming. I don't think my TV has Digital audio out [ CHARLES Feb 22, 2016 ]
Absolutely. It has both digital and RCA analog inputs, and I have a TV connected to it with the former. Note that because it is a stereo receiver, you won't get surround sound from TV, movies, etc. If that's important to you, you should look at an AV receiver, e.g., 5.1, or 7.1. [ Matthew Feb 22, 2016 ]
Yeah no problem works great. [ SHAWN Feb 22, 2016 ]
The following "placement tips" are listed in the Owner's Manual for this receiver: -Maintain a clearance of at least 12"(30cm) on each side of, above and behind the unit. If you install the Stereo receiver in a cabinet or other enclosed area, provide cooling air within the cabinet. Under some circumstances a fan may be required. -Do not obstruct the ventilation slots on the top of the Stereo receiver or place objects directly over them. -Do not place the Stereo recei ver directly on a carpeted surface. -Do not place the Stereo receiver in moist or humid locations, in extremely hot or cold locations, in areas near heaters or heat registers, or in direct sunlight.

No this is why I set it back for an upgraded amp. I require an out put for my Hafler power amp to run my Klipsch Cornwall speakers. [ Tim Sep 10, 2018 ]
No; this model does not offer the monitor loop required for use with the Bose 901 speakers. I usually recommend the Yamaha R-S700 for use with the Bose and it's been a great solution: http://www.crutchfield.com/p_022RS700/item.html I hope that helps!

No, Bluetooth feed to the receiver but wires to the speakers [ BRIAN Jan 16, 2016 ]
if the speakers are connected to the receiver you can pair them thru the receiver wirelessly [ DANIEL DEL Jan 16, 2016 ]
I would think this would be compatible with any speakers [ David Jan 05, 2016 ]
Not sure about those speakes. I am using standard in-wall speakers and they work fine. Very happy with the 3770 tho [ John Jan 04, 2016 ]
Enter an answer to this question.Does this unit have Bass Midrange and Treble controls? [ Tdjacw Nov 26, 2017 ]
It's all about the proper file-folder structure when you copy the content to the USB drive from your computer. Properly titled folders & files will be displayed on the Harmon Kardon and you can navigate them using the supplied remote control. You will find this information, and more, by clicking the "Details" tab on the receiver's main webpage. From there, you can download the Owner's manual (Under the "What's in the Box?" heading) or you can scroll down below the "Features & Specs" table to find our "Hands On Research" section. I hope that helps! [ Ryan Nov 20, 2015 ] Staff
yes [ KRISTEN Sep 19, 2015 ]
I have no idea. [ Richard Sep 02, 2015 ]
I don't believe so. You can stream music over Bluetooth, but you cannot control the amp over Bluetooth. There is a HK remote app for android. It doesn't use Bluetooth, but it will connect to the amp over WiFi. [ DANIEL J Sep 02, 2015 ]
Joe. In all Apple, so I can't answer for Android. There is an app for iOS called H/K Remote. I assume it is available on other platforms. It's functionality is questionable. If you want to achieve full, smartphone control of your HK3770, get a Harmony Remote with a Hub. That's all you need to run your AV from your phone, tablet or handheld remote. They just added perimeters for the HK3700&3770. [ BILL Sep 02, 2015 ]
I'm a Mac guy, but I figure this would work depending on the output settings on the PC. My question would be "why"? There are probably other outputs on the PC. Plus, I doubt you would be able to control the PC playlist using the HK remote. It would be an audio output only. I'm guessing it would work. [ BILL Jul 26, 2015 ]
Sorry, I don't know. I only use it for internet radio. [ David Jul 26, 2015 ]
Volume Is not stable when connected to iPod , the unit made most with plastic and most of all its made in China.... [ ALISON Jul 25, 2015 ]
Kim K: YES you can. The beauty of this receiver is that apart from Bluetooth and USB inputs (digital) it can also receive analog input ( phono, CD players, etc). I highly recommend this receiver for the clarity of its output. [ Pedro Jun 08, 2015 ]
Yes, any sound you can put over Bluetooth from your iMac or iPad/iPod will play. The bummer is you can only have one BT device at a time paired - that means if you have an iPad paired and you want a laptop paired, you have to disconnect the old and connect the new device. It's kind of lame, but overall it works. [ Aaron Jun 08, 2015 ]
I use my iPad to stream internet radio using Bluetooth. and it works great. I would think the iMac should work. Love this receiver. [ Alfred Jun 08, 2015 ]
Hi Kim, I am actually listening to music from my iTunes library from my iPad right now. It was the reason I bought this receiver. It works great and sounds very good sonically. As long as it's streams from your device Bluetooth, you should be fine. Jim [ JIM Jun 07, 2015 ]
Yes you can .. I play music from my PC and iPhone threw Bluetooth on it.. [ JAMES Jun 07, 2015 ]
I stream Pandora and other sources from my iPad using the USB input, it sounds better than Bluetooth, but Bluetooth should work the same. [ jon Jun 07, 2015 ]
I would assume there is a replacement from Harmon Kardon but I don't know the cost. I personally still have my original remote. [ David May 12, 2015 ]
We don't carry a direct replacement. You could contact Harmon about getting one here: http://www.harmankardon.com/contactus You can also find our all-in-one style remotes here: http://www.crutchfield.com/g_16000/Home-Remote-Controls.html [ Jeff May 12, 2015 ] Staff
Seems your question was misdirected to the customer forum [ BRENT May 12, 2015 ]
most of the times other companies have a multi device that can be programmed for any device by the companies device code. very simple around $40. there is a device program code book that comes with your new purchase. [ FELIX C May 12, 2015 ]
Hi Greg, we use it in our office and have no problems connecting from distances up to 60 or 70 feet away and could probably connect from farther, however there are no walls in our office so I couldn't speak to how much the walls of your home could interfere with the signal. [ NICHOLAS Feb 02, 2015 ]
Not sure about range but we've been outside on our deck maybe 100 feet away from receiver and have had no problems. I don't like using our smart phone with the receiver because whenever it rings or gets a text/email, the music turns off. We only use the Bluetooth when our internet is unstable. [ David Feb 01, 2015 ]
I'm not entirely sure the receiver determines that. I think it depends on how powerful your phone is since it is what is sending the signal. I believe the receiver is a passive listener. But in any case there are three standard ranges according to Bluetooth the company: ~3ft, ~33ft, ~300ft. I'd guess it was the middle one. Mine works at about 30 feet fine. It should work if you are within that range although walls/glass doors will shorten that distance some. Hope that helped :D [ Brett Feb 01, 2015 ]
Haven't' tested full range but works anywhere on the first floor of a 3500 sq ft house, probably a good 50' at least [ KEVIN Jan 31, 2015 ]
Good question. I decided to plot this out within the house. I was able to get 47 feet from the receiver before the signal started to sputter from an iPhone 5S. This was slightly indirect with some wall coverage. I can't speak to exterior wall interference. And with a backyard of snow, I aint going out to calculate a Bluetooth signal. [ BILL Jan 31, 2015 ]
I have mine installed inside the exterior wall of a three season room near our pool. Inside the room it is absolutely reliable with iPads and iPhones. About 30 feet away outdoors is where it starts cutting out [ BRENT Jan 31, 2015 ]
I use at fairly short range 10-12 feet ... I could not tell you how far as I have not tested that. And beside I haveno idea how far apart or how many walls exist between your pool and living room...or why if you are at the pool why you want music in your living room. The receiver sounds fantastic though [ Richard Jan 31, 2015 ]
Typically 30 feet, but depends on interference and objects between. [ Jason Jan 31, 2015 ]
Robbie D. Yes, balance and tone control are adjustable for each separate input. [ Robbie D Mar 01, 2015 ]
After reading your question, I looked for a balance control. Had this HK for a year now and never noticed that there is no balance control. [ David Dec 27, 2014 ]
Sorry, no balance control. This is avery straight forward stereo unit. There is no "mono" function that shows either. What goes in, go out exactly. [ ROBERT A Dec 27, 2014 ]
The 3700 and 3770 are essentially the same receivers. The major difference is the 3770 supports Bluetooth connections. I couldn't find a Balance Control on the 3770 anywhere. [ BILL Dec 26, 2014 ]
Josh: Might want to rephrase your question in English. I got the phono part. Yes, you can use a turntable. I can now play, what my generation used to call "records". Yea! [ BILL Oct 29, 2014 ]
Wish I could help, but I don't know what you're asking. I only use it for Pandora which is controlled by my Onkyo. The HK is for outdoor sound only. I can tell you it's an awesome receiver, Sorry, Dave. [ David Oct 29, 2014 ]
It is phono-ready, and can play almost any flavor of MP3 or WMA audio formats, except lossless WMA. There is no indication that it can play FLAC. The DLNA support seems to be pretty good. I have a dedicated NAS on the same network subnet at the HK receiver and I use the NAS to serve up highest quality MP3 (ripped with LAME-extreme VBR) and things sound excellent. this unit's strength is in the multiple ways of connecting to it - Bluetooth (3770), direct (internal) conversion from external media players, ethernet, analog RCA phone inputs, and optical inputs that I have my TV connected to. [ KEVIN Oct 28, 2014 ]
Sorry I do not understand the question. We play our playlists through the HK 3770 both wireless (Bluetooth) and plug in from our iPhones and iPads. Hope this is helpful. [ WILLIAM J Oct 28, 2014 ]
If you use the receiver as a media player (such as plugging a thumb drive with just music files) no, you cannot play flac. But connect anything that can play flac with all digital connections and it will. My setup is a small media computer with an optical audio port connected to the optical input on the receiver. In this setup the receiver doesn't have to read the files (the computer does that) it just processes the signal from digital to analog, amplifies it, and sends it out to the speakers (all beautifully I may add). So file type is irrelevant to the receiver this way. I hope that helps. [ Brett Oct 28, 2014 ]
I do not think it can output to bluetooth devices. [ JARED Aug 25, 2014 ]
To my knowledge, no. Bluetooth is input only. By the way, works great. Stream Spotify [ Ralph Aug 23, 2014 ]
Nope [ COLIN Aug 22, 2014 ]
No, you cannot. The Bluetooth its only available up as an input [ DANIEL J Aug 22, 2014 ]
I tried to do this with a small BT speaker I own and the menu on the HK will not recognize it which leads me to believe the BT feature is for input only. I think I get where you are going with this, using portable speakers around the house or out on the deck. I do this through Airplay compatible speakers. However, these are going to be more costly than any BT speakers. Even though this doesn't help your quest. I did find that pairing my iPhone with the HK-3770, allowed me to control limited playlist controls using the HK remote. Pause, play, previous & next track, etc. I thought that was a nice touch. [ BILL Aug 22, 2014 ]
Harry, The output is filtered. As far as I know it is a set crossover with no variability. You can change the "bass" setting under tone control, but that will affect your regular speakers as well. I believe the crossover setting on the HK is relatively high, as I use the crossover on my sub to attenuate down to about 80 Hz and the bass sounds cleaner. I see on your polk there are two inputs? I would recommend plugging into the non-LFE input and using the crossover on the sub to get it sounding how you want. The HK will still filter the signal but then your sub will filter it further, just make sure you are plugging into the Sub Out on the HK. Definitely took me a while to get my sub sounding how I wanted though. What helped me actually was calling Crutchfield Tech Support, they have professionals who are happy to help with questions like this, they helped me with setting my crossover and sub placement. Hope this helps! [ COLIN Jun 02, 2014 ]
I have no idea what your acronyms represent, but I do understand "booming muddy mess". I am also very disappointed that there seems to be no crossover control for my subwoofer. I have the same, uncontrollable, "booming muddy mess." I replaced my HK AVR140 with the HK3770. I considered the AVR140 to be a low-end HK receiver, but it had terrific bass control. I expected the same level of control on this receiver, but didn't get it. I've had better bass control on a rental, U-Haul truck radio than on the HK3770 [ BILL Jun 02, 2014 ]
