Harman Kardon receivers are known for combining a stylish design with sound that packs a punch. That's just what you'll get with their HK 3700, along with some pretty cool features for enjoying digital music. With connections for an iPhone®, USB thumb drive, CD player, and turntable, along with network connectivity, there are lots of ways to enjoy all your music with this versatile receiver. It's a great option for music lovers seeking a stereo system with classic sound and modern connectivity.
Harman Kardon has been working to make their receivers more energy efficient without compromising sound quality. The HK 3700 represents the fruits of their labor. It utilizes Harman Kardon's GreenEdge™ technology. Rather than redesigning the Class A/B 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 3700 is Internet-ready — connect it to your network router to open up lots of wireless listening possibilities. 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 and play locally-stored songs wirelessly through your system. App control requires a wireless home network and a wired connection between your receiver and your network router.
The USB port on the HK 3700'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.

Great value for money; good to the ear and to the eye
Sounds good and does everything I need it to do. Downside no bass treble, tone controls that I am aware of. Needs to come with better operating instructions
Pros: Good sound very powerful
Cons: Need better operating instructions. Because of the power I now need to buy new speakers LOL
I have seen 2 reviews now that say this has no balance control. I have never used a balance control in my life but if you need it, YES the HK 3700 has balance control. Select "stereo" from the handset, select "tone control", cycle through "bass" and "treble" (hit tone control each time) to "balance". Use the right left arrows to set balance. (It wold help if HK would revise the manual to show this.) In fact, fiddly controls are the main shortcoming of the 3700. As to the good stuff, never had a class D amp before. This runs cool (at least at the moderate volumes I generate) pushing a pair of Epos Epic 1s. Everything on my iPhone (60 gb), all classical, sounds newly minted. 320kbps MP3 now sounds very similar to my CDs. Wanted an HK receiver since I was a little shaver (and could only afford Kenwood and Sansui). I think it looks great--not that different from the HK receivers of my youth.
Pros: Digital in from iPhone Lightning connector, bypassing not only the headphone amp, but the Apple DAC. No humming or popping or fiddling with iPhone volume.
Cons: Unintuitive distribution of control between handset and receiver. Both handset and receiver buttons do not work in all modes. Manual needs a revision. Build quality seems short of NAD and Cambridge Audio.
After 3 decades my component system was at the end of its trail and I needed to simplify. The HK3700 so far has fit the bill. Clean sound. Powers all my analog sources, as well as iPod, and with a bluetooth adapter even streams my Nexus music files. I've grown to appreciate the remote. Speaker replacement/upgrade next.
Pros: Prompt delivery. Helpful support. Competitive price. Nice sound.
Cons: Manufacturer operating instructions not very helpful. Perhaps it's a generational gap between the analog (babyboomers) versus the digital (millenials+). Plastic face, although clean looking, not the same as the brushed aluminum face of my previous amp and tuner.
I really don't have any major gripes with the Harman Kardon 3700. Easy set-up, great sound quality, and a great handful of features like Internet radio, network connectivity, and all the jazz. My only issue, and it is partially my fault for not double checking, is that there is no auxiliary input, and no Bluetooth, both available on the 3770. Purely due to this fact, I'm thinking about upgrading.
Pros: -Great sound quality -Easy setup -Easily configurable features like Internet radio, network connection -Great aesthetics
Cons: -No aux input or Bluetooth, expected for the price point.
Lots of features for the price, I would recommend this unit. 5 stars for Crutchfield; I was able to compare units by feature, competitive on price, got the unit in days, even included cable labels!
Pros: 1) Good unit, LOTS of features for the price. 2) This was the only unit I could find the feature set I wanted in this price range. 3) iPod support and vTuner are very nice 4) This unit is replacing a 1991 Denon mid level receiver that is slowly dying, this is an acceptable replacement, more features, not as high quality, not as user friendly. I would recommend this unit with the following caveats:
Cons: 1) No instruction manual in the box only a quick setup. Have to download manual in order to fully setup unit. Poor instructions/menu flow, not intuitive. 2) Poor front panel interface, cannot setup unit without remote. Given what consumers are accustomed to today the software/user interface is right out of the 1990s. 3) Wifi support in consumer electronics can be added for a couple bucks, very odd choice to only support wired Ethernet but that seems to be the convention in home audio.
This receiver is just what I was looking for to replace a two channel Onkyo receiver that died too quickly after the warranty expired. I am using this mostly to listen to Internet radio. Setup was simple; I was able to add my favorite stations to V-Tuner via my computer without a hitch. Buttons on the receiver are a bit difficult to see, however the remote can perform all functions. The receiver easily drives my ceiling-mounted Klipsch speakers.
Pros: Easy setup, Internet connection via ethernet, V-Tuner has all stations I need worldwide, nice big & bright display, great remote.
Cons: Buttons on receiver are difficult to see, as it is on a shelf below my eye level.
First off I love the retro look, when it comes down to the functionality of the receiver there is nothing I have to complain about. It powers my two infinity floor speakers and my 8" sub perfectly. Nice size, not too heavy. Perfect receiver for someone not wanting to break the bank but who needs a decent amount of power.
Sleek design, plenty of power for my small office, message display is easy to read, remote control is handy.
Pros: Lots of features, sounds good, has subwoofer pre-out and USB/IPOD input.
Cons: Lacks L/R balance control. The push buttoms on the unit feel delicate. The remote control is handy but requires practice to readily manipulate.

Output Power: The Harman/Kardon HK3700 stereo receiver features a 85 watt x 2-channel (8-ohms, 20Hz-20kHz, THD 0.07%) amplifier for great sound quality with little distortion even at high volumes.
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.
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 HK3700 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. You can control playback of your streamed audio files from the network receiver's remote control. The receiver also supports ID3-Tag and META tag information so song title, artist name, and album name can be displayed from the unit's front-panel display.
AM/FM Tuner: The Harman/Kardon stereo receiver features a built-in AM/FM tuner with manual, seek, and preset tuning (auto/manual). You can store up to 30 AM/FM presets (in any combination). You're able to scan through these presets (5-seconds each) to help you search for your favorite music. You also can tune directly to a station using the numeric keypad on the included remote control.
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).
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.
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 HK3700 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.

Like the name brand and it fit my needs. [ Jackie Mar 29, 2016 ]
I needed a receiver with a sub-woofer output for my Bose speaker system, and a USB port to play my iPod. All other features are a bonus. My past experience owning a Harman Kardon amplifier was that it was premium equipment. [ Robert Jan 26, 2016 ]
Yes can drive 2 pairs 8 ohm speakers at the same time but will be at half power for each pair if both are on at the same time. [ Gerald Apr 20, 2016 ]
That is how we have it set up. Four speakers in one large room.... [ Karl Apr 19, 2016 ]
Yes, that's a safe assumption. It probably wouldn't drive 4 ohm speakers paralleled at 2 ohms though. [ TIMOTHY J Apr 19, 2016 ]
Yes, this has Speaker A and Speaker B channels, which can each drive a pair of 8 ohm speakers (together or independently) [ TOBIAS Apr 19, 2016 ]
Not sure--I'm only powering two Klipsch ceiling speakers. However, it's a great receiver. [ JEFFREY Apr 19, 2016 ]
I Used a standard network cable directly to the router. I listen to Internet radio almost exclusively now. Love it [ Scott Nov 05, 2015 ]
Since there's no built-in WIFI, you have to connect with an Ethernet cable from your router. [ JEFFREY Nov 05, 2015 ]
You should be able to with Ethernet connection and remote app on your mobile device. [ Gerald Apr 03, 2015 ]
I am not aware of a way to do this. Rhapsody requires client software to exist on the receiving device (i.e. the app you load on your computer). The Rhapsody client does not exist on the HK3700 so it cannot receive and play Rhapsody directly from the internet. And I am not aware of a way to stream Rhapsody from a PC to the HK3700, maybe someone else does. I use Plex to stream mp3 files on my Mac to the HK3700. But Plex cannot stream out from a Rhapsody stream in that I can see. On the web it looks like when using Rhapsody on a home stereo receiver you look for one that comes with the Rhapsody client built in. On my HK3700 I stream either from 1) computer resident files via Plex or 2) vTuner via the stations/sites they support. For me this is more than sufficient. [ JONATHAN Apr 02, 2015 ]
No answer for that. I use it mostly for streaming Internet radio, & it works flawlessly for that. [ JEFFREY Apr 01, 2015 ]
No [ SCOTT Apr 01, 2015 ]
Does this reciever have the traditional h/k sound quality [ Jon Mar 07, 2015 ]
The internet radio works very well, and it sounds great. [ DENNIS Apr 23, 2014 ]
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Jeff Apr 15, 2014 ] Staff
