Experience room-filling sound with impressive musical detail and transparency. The NAD C 375BEE features a sophisticated design and beefy construction to bring out the best in all your music from the lowest, wall-shaking pedal notes of a pipe organ to the delicate reverberation of a solo acoustic guitar. This integrated amp delivers 150 full-bandwidth-rated watts to each of your stereo speakers for powerful, undistorted sound, even during your music's most demanding passages.
The C 375BEE employs many of the same high-end features found on NAD's top-of-the-line Masters Series components, including NAD's exclusive PowerDrive technology. This unique circuit automatically senses your speaker's impedance, then optimizes the amp's power supply settings to deliver the most dynamic power possible. This allows it to easily drive low-impedance loads, including many of today's high-end speakers, which often run closer to four ohms than eight. Plus, a patented distortion canceling circuit in the amp's output stage ensures your music stays clean and pure.
Along with all of its advanced technology, NAD gave the C 375BEE a big helping of good old-fashioned construction quality. This integrated amplifier boasts a heavy-gauge steel chassis for added durability and vibration resistance. Its power supply, the heart of any amplifier, utilizes an interference-canceling toroidal transformer and heavy copper buss bars to channel enormous amounts of current to the custom gold-plated speaker binding posts. Additional premium-quality internal components such as four pairs of discrete high-wattage output transistors per channel allow the C 375BEE to handle prolonged high-power operation effortlessly.
This integrated amp offers enough inputs to connect seven audio components. Its modular design even allows turntable owners to install an optional NAD phono module for listening to vinyl. (Or, connect NAD's outboard PP3 phono preamp.) Two sets of main speaker outputs provide hookups for an additional pair of speakers. Separate preamp input/line-level output jacks let you use the C 375BEE as an independent power amplifier or preamp for future system expansion, or to easily add a powered subwoofer. And the included remote gives you easy control of the amplifier and the other NAD audio components in your system.

Great component, extremely powerful, with clear, precise sound
This is the best sounding integrated amplifiers in its price range. It's sounds as good if not better than many amplifiers that cost twice as much and more. Keep in mind it's all about how you par it. I paired mine with a pair of Polk Audio LSiM707. The combination is outstanding. The amplifier can deliver more power than you'll ever need for these speakers. The highs are super clean and the lows are outstanding. This amplifier does not sound processed. It's super clean. The best thing about this amp is that it delivers high amounts of clean power when needed yet it delivers a pure delicate sound when required. I have to agree with many of the other reviewers that this amp makes good recordings sound incredible. However, it definitely points out the flaws in the poor recordings. If your listening space has good acoustics you will feel like the musicians are right in front of you. I would recommend getting the NAD DA converter too.
Pros: This is a bare bones no frills amp that has everything good audio requires. NAD spent the money on delivering great sound.
Cons: I know this is contradictory but I wish bass and treble controls were accessible via the remote. Our amp is in a media closet which is not in the same room. We do have an IR remote in the room so we can use the included NAD remote.
I think the basic specs say it all with this integrated amplifier: 150 of NAD's Full Disclosure Watts per channel with a THD of 0.009%. I like simplicity and I wanted an integrated amplifier that could deliver clean, confident power to my speakers and this amp does just that. I also didn't want to pay for any features that I wasn't going to use anyway. I wanted to listen to two-channel music, without all the bells and whistles of wireless music, fancy displays, and other things I consider gimmicks. I like that with this amp all my money went to build quality and good, clean sound. The amp feels solid, from all perspectives. Taking it out of the box it is immediately clear you're holding a well-built piece of equipment. The rear panel is laid out well. The controls on the front have a very satisfying touch to them. Much more importantly, the sound it delivers feels very solid too. I use this to power two Polk RTI-A9s, which people always say need plenty of power to sound good. Listening to several types of music I have never felt that the amp is lacking. Throughout the full frequency spectrum it easily and confidently delivers the music. I ordered this together with the Polk speakers, which were on backorder and therefore arrived a little later. Meanwhile I used it to power my old Yamaha bookshelf speakers. I couldn't believe how good they suddenly sounded with an amp that had full control over the drivers. I'm very pleased with his amp.
Pros: Plenty of power; 150 watts per channel continuous and up to 230 dynamic power. Very clean power with no distortion anywhere in the frequency range. Nice, understated looks. I should add, in all pictures it looks black, in reality it has a refined dark graphite look.
Cons: I had read some concerns about it running warm. I was surprised that with my 6 Ohm Yamaha speakers it ran warmer than with my 8 Ohm, power-hungry, Polk speakers. Overall though, NAD seems to have done a nice job with discharging that warmth. I have it inside a BDI cabinet that has ventilation openings and it never gets alarmingly warm, more like what you could expect from a piece of hard-working electronic equipment.
Works like the reviews said it would. Great sound and plenty of power.
Great sound, adequate power. Bass support could be better, but overall a good listening experience.
I just purchased this amplifier in June 2015. It has clean, crisp sound and plenty of power. I use it with an NAD CD player and a Bose sound system and it performs exceptionally well. It's worth the money I spent for it.
Pros: Solidly built, good heavy structure, simple to use. I really like the simplicity of the controls and the design of the rear panel and connections.
Cons: None that I can find
Needed stable power to drive 4ohm/86db ribbon speakers. Great fit for my ear at this price point. Setup took 5 minutes and I was listening to music. Volume knob
Pros: Enough his current power to deliver 4ohm speakers with ease.
Cons: Highest of highs slightly rolled off.
This is my first stereo integrated amp and NAD purchase but I am more than pleased with the product. This amp provides more than enough power to run my Klipsch RF-7ii speakers. The front panel is very simple and the buttons/knobs have a high quality feel. The amp runs warm even at lower volumes but is yet to get as hot as the Onkyo AV receiver it has replaced. I purchased an open box and received a flawless product. Thanks to my advisor Blake for the recommendation.
Pros: Tons of power!
Cons: A backlit remote and a matching blue light for the volume knob would have been nice, but honestly I'm just trying to find something to complain about.
While I would rate the basic features quite adequate, the as-received quality is not what it should be. After spending some critical listening and troubleshooting time, I found the Accessory Input (I was using for my DAC) has a noticeable gain difference between left and right channels. I fixed my problem by using other rear inputs, but for this money, things like this should not happen. This combined with the number of Refurb units one sees on Audiogon (for example), leads me to feel the manufacturing quality still has a long way to go. My problem is minor enough that I won't return it, but I am annoyed I had to suffer it.
Pros: Great basic amp with solid power and features.
Cons: Ongoing quality problems experienced by users - including me.
I was looking for an integrated amp for my newly acquired B&W CM10 speakers. Read many reviews, and then acquired an NAD C 375BEE, a Peachtree Nova120SE (which I left on for a day), and a Rotel RA-1570. The NAD was the clear winner. It was more musical and felt more lively. I found myself rooting for it because of the richness & the clarity I was experiencing. The warmth of the NAD sings, and who wouldn't appreciate that when listening to -- music. It also has a strong & articulate bass, whereas the other two are more mushy. Altho I do not listen to my music loudly having the extra power of the NAD is certainly nice to have when you want to raise the intensity. Even the remote control is a clear winner. I most definitely recommend the NAD. I compared these amps using the Oppo BDP-105D.
I replaced a 22 year old Hardon Kardon Reciver with a NAD 375BEE amplifier and it blew my face off! Very Happy! I'm driving 2 polk RTiA9 speakers and a polk 660 wi sub.
Pros: Outstanding power! A simple but great designed AMP!
After a lot of research trying to decide whether to purchase a reciever, integrated amp, or amp and preamp I came to the conclusion this product looked like the best product for the money available. My interest is focused on 2 channel stereo using Klipch RF 82 II' s I purchased myself for Christmas last year. I have been upgrading from my old late 80's Technics. I ordered this Friday morning and it arrived Monday afternoon in AZ. The service from Crutchfield was outstanding as was my adviser Tim. This unit is rated conservatively at 150w per channel matching my speaker rating. The clarity and tone separation is the outstanding sound I was looking for and I was not willing to compromise after my last system was used a good 25 years. I came close to ordering a lower output rating but felt I would be disappointed. This amp does not disappoint. I mostly listen to Classic Rock and some newer music like the Rod Hot Chilli Peppers using my iPhone and Pandora. I also listen to CD's. I have a 10 Klipsch sub that I purchased a few months after getting the RF 82's because I felt I was lacking the deeper base frequencies. With this amp and after breaking in the RF 82's, I don't even the sub anymore. Very satisfied with my choice and Crutchfield.
Pros: Outstanding quality, sound, and power. No audible distortion rated at .009 THD.
Cons: This puppy is heavy. The shipping weight was 42 lbs and think the specs say it's 33lbs. Not really a con because you get what you pay for. It is heavy though if you consider that con. Otherwise the only issue is nothing.
This amp sounds absolutely phenomenal from the minute you turn it on. It's the first amp I've ever owned, in almost 30 years, that I didn't have to touch the tone controls. I just put it in defeat, and left it there. I listened for almost 3 hours, playing various vinyl and CDs. My last amp, I used the tone controls as kind of a loudness button. Not with the 375 BEE. It sounds wonderful no matter what volume you listen at. If you've been on the fence about buying a 375, "Just Do It", you won't regret it. It's worth every penny and then some.
Cons: Can't find any.
I bought this amp to replace my Denon amp that was 25 years old. I am totally amazed how much difference in made in the sound. The mids and highs are much smoother. The bass has more punch. I have heard tube amps before, but did not realize that solid state could be made to sound this good. I'm totally impressed. My system sounds very high end now. I highly recommend it.
Pros: Excellent sound for the money.
Cons: Speaker wires have to be fed into the top of the posts and cannot be fed through the bottom. It is a little annoying, but minor.
This amp arrived yesterday, late afternoon, bouncing down our driveway with the sheep&cows all standing, watching in awe.. I opened box, did quick scan, and figured would wait until TODAY, to get a full day in and get it hooked up to listen & compare...My Wife knew better..Last night, about 7pm, got the last wire hooked up to my Technics 1200GLD which runs a Ortofon 2M Black cartridge..I fired up the twin tower Polk RTi-A9 speakers, started off with a classic 1970'ish 45rpm record, went to half volume, and heard some of finest notes and music reproduction had heard in quite awhile!!! ..Now, I am a bit oldschool, (was doing this, and playing vinyl many years before Crutchfield was born, ) but had used many amps, turntables, and speakers over the years, but when I called Crutchfield just a few short days ago, to explain what I was running, and to get advice for a new power source, they were SO HELPFUL, and quick with response and advice to my situation, that I did not hesitate, and placed order for this Amp that very morning..I am so glad I had.. I played vinyl ( Have over 10,000 albums&45's) until 9pm, and wife was getting anxious as was missing some tv show called survivor, or something like that...I played ALL genre of music, 40's, 50's, 60's, 70's&80's, Classic, Rock, Jazz,Soul & some big-band...Everything I challenged played so well, and with such rich, full sound ! I would recommend this amp to anyone..Price, Performance, & ease of installation is superb..!
Pros: Price is good, function & ease of use/hook-up is great
Cons: I have to replay 10,000 + vinyl records, to "HEAR" them all over again ! ! !
I had believed that amplification had little to do with sound quality and that, if you gave a set of speakers sufficient power, the speakers were 99% of the sound quality equation. Having said that, I switched over to this amp from a Yamaha RX-797 (an older top-of-the-line receiver), and was truly surprised. The best way I can describe the sound of this amp is "crisp". Each and every sound has its distinct beginning and end, no individual sound is blended with the next, nor is any frequency accentuated. I'm using this with a small pair of monitor speakers (5-1/2 in. & 1 in. drivers), and the level of control this amp has over the drivers is obviously much, much better than the Yamaha. All sounds and transients are reproduced so much more clearly. ...as Jeremy Clarkson would say: "POWER!!!"
Pros: Typical NAD quality build. Crystal clear power. Wonderful driver control. Bass is super crispy. Soft clipping. Front panel aux jack. This amp will drive ANY pair of speakers.
Cons: Gets quite warm. Volume adjustments using remote control are not very fine. Remote control only works with other NAD products. When listening with headphones (both speaker sets off), pre-out 2 is still active (this is a problem if you have a sub connected and you're trying to be quiet).
I've alwasy been more of a traditionalist using amps and pre-amps; however, after much review I decided to give NAD's 375 a try. I have to say, I was pleasently amazed at how clean the sound was. I truly could not tell the difference between some of the previous amp/pre-amp components I'd put together. Coupled with their 565 CD player, the sound has been very vivid with lots of detail. I paired them with a set of B&W CM9's. I'm very happy with the product.
Pros: Very well built, good quality, clean sound, suitable power
Cons: Wish it had digital audio inputs (i.e. fiber optic cables) and little bit more power (i.e. 175 or 200 watts).
Use this to push 2 paradigm studio 60's, also have a klipsh 300 watt self powered sub that I hooked to the b channels which seems to work really well that way, adds just enough but not too much. Had an Arcam 120 watts channel that was never this crisp and clear even when new. Was never happy with the paradigms before now.
My system has never sounded this good. The Gallo speakers, especially, seem to pair well with this integrated amp. I'm waiting for the NAD CD player to arrive in order to see if the sound can be made even better. I'm not a true audiophile, but I know good sound when I hear it without knowing much about the tech jargon.
I bought this with the hope it would power my Cerwin Vega XLS-215's and I was NOT dissapointed !! Rocks the house like none other. Half the time I can turn the Cerwin Vega Sub off. I would like to hear this with a pair of the Polk A9's thou. Very good Amp and would recommend to all who have big speakers to drive.
Pros: Easy set up, great sound. Liked two inputs for tape decks. I still have two and a EQ.
Extraordinarily good receiver. I pair this with PSB Synchrony Two B bookshelf speakers, staged using Jim Smith's "Get Better Sound", and the overall setup is marvelous. Source is usually 96khz recordings played on a Macbook through Audirvana, output through USB to a NuForce DAC, then out to the NAD. I try doing comparison tests, and just get lost in the music and forget what I'm supposed to be appraising. Be forewarned, if you have low-quality recordings this receiver will show no mercy, and the flaws will be evident. Good recordings have a presence and vitality that's really hard to beat. I bought a scratch and dent, have not been able to locate either scratch or dent, but it was arrived very securely packed with Crutchfield's usual speedy delivery. Expensive, and heavy, but if you take music seriously this is well worth it. It has the power to drive speakers like the PSBs, with no need for a sub in a smaller room. Bass is not tight, but I don't like tight bass anyway, too dry.
Pros: Everything above. Such a big step up from what I had before it's hard to describe.
Cons: Heavy, and the remote sometimes doesn't respond well. The remote seems under-engineered compared to everything else.
I needed to upgrade a Denon AVR system we using for a bar/restaurant sound system so I called Crutchfield and spoke with Brian about my situation. We weren't using the receiver portion of the Denon so he suggested the NAD C37BEE to accommodate our 5 possible feeds for music along with the Niles HPS-6 since we have five zones of music, each with its own volume control. This works perfectly and has plenty of power for our business. Thanks for the expert advice and making the order process so easy!
Pros: Easy to set up and sounds great! Fantastic individual products and a superb pairing.
Cons: The NAD came strapped for Pre-Out 2 which has a small volume control on the back of the unit and completely bypasses the front control. Not something I expected or was able to figure out by myself. A call to Crutchfield's tech and a little troubleshooting solved my problem.
I upgraded my speakers with pair of B&W 683 and run with Yamaha A-S 500 but not power enough! After research and review I order the NAD C375BEE from Crutchfield......about 15 minutes hook up...wow..........this amp has very clean sound and drive my speakers perfected! I even get rid of my sub woofer and don't need it any more! Very special thank to Crutchfield staff help me out to solve the problems that difficult for me to find the right amp for these monster speakers! Also special thanks to BRIAN (Tech staff) and Bill (a person take care my order) . This amp very powerful and highly recommended . Very very happy owner . Go NAD C375BEE
After 29 years, and the need for a second repair in the last 4, the time came to part with my trusted Carver M-1.5t amplifier. But what could replace such reliable and wonderful companion? I'm a believer in big power, but Bob Carver's new company, Sunfire, entered into the dark side of expensive. NAD is a company with a reputation for good-quality, no-frills stereo components, and the C375BEE intrigued me for I was sure its 150wpc rating was probably way down on the conservative side. I was not dissappointed. I'm back to enjoying wonderful explosive transients from my music collection. Some would consider my equipment consisting of this NAD paired with my BOSE's 901s, and my $120 CD/SACD (no turntable, sin of all sins!) as misguided, if not outright ignorant. As a bonus, I'll add that my speaker cables are plain 18 gauge zip cord wire.
This amp has a very clean sound-it truly reminds me of tube equitment when the sound was real and natural,very little to adjust,the sound is just perfect,great with bose 901s,I even got rid of my subwoofer,dont need it anymore,this amp reaches lows very well,clean and undistorted. Go listen to one and youll know what im saying. Yes the price is up there but you buy something like this once in a life time and it will outlive you and I and it kind of goes back to the saying you get what you pay for. If your looking for high end stuff here it is.
Pros: This amp is now married to my Bose 901 s,talk about a match made in heaven-I love the soft clipping feature included with this amp,i have it on but its such a clean sound I havent yet seen it work-its a power house of clean clean sound,this amp reminds me of super tube amp with perfect lows and highs. Great investment !!! Should have it for many years to come,very sturdy and solid built and you must respect its weight,if it weighed less you may wonder what your paying for.
I upgraded this amp from the smaller NAD 326BEE and all can say is Wow! The amp is so clean and transparent that it really should be bumped to their reference grade line-up. Its hard to describe the sound, but its clean , accurate with no coloration at all. Seems to drive my speakers much louder and with TONS more detail than my older onkyo 100x2 amp. Overall one of the best amps ive ever owned. They are running Dynaudio Focus MkII speakers at 4 ohms. Sound is so good its scary. Im happy i didnt buy one of those commercial spec amps from best buy. There is a major difference btw NAD and other main stream brands. You do need to give the amp a few days to break in to hear its full potential.
The 375 is in an entirely different class than most of it's comparably priced competition. It's not the power, it's how it's delivered. Many of the amps I've used recently are gutless when compared with the NAD. I've ran this amp with a wide range of speakers. From inexpensive Infinity's, $3K PSB's, Vandersteens', and power gobbling Magnepans. For the $ spent, it's the best I've used. I'm tempted to buy a second one for running them bridged. It's a great product. Audition one for yourself, I believe it will sell it's self.
This integrated rocks. No matter what I do or the type of music I listen to, there is no distortion and this amp will feed you as much dynamic power as your speakers require. I run this amp with the C375 CD and PSB Image T6 and a self powered JBL sub, and I have never heard such spacious detail in an amp at this price, or twice this price, before. It makes everything you listen to sound better, and wait until you hear the horns that it produces. Incredible!! Very, very happy owner.
I upgraded my speakers to the new 5000 series drivers. My integrated tube amp drove them well but they craved more power. After research and reviews, I ordered the 375 BEE from Crutchfield outlet. Ordered on a Tuesday afternoon and received on Thursday afternoon. My speakers are 4 ohm and this amp is rated at 150 wpc. That is conservative. It easy does 200 wpc and can output up to 400 wpc for brief periods when needed. The sound is detailed - mids are clear and might I say tube-like. Low end is excellent. For solid state it does not have any of the harshness of lesser solid state gear. Visibly it cannot match my tube amp for the wow factor but the sound quality is definitely better. I can drive this amp hard and instead of being fatiguing it simple creates massive amount of high quality sound that just hits your body and amazes you. Highly recommended and as always, Crutchfield does it the best.
I am rather surprised at what I got! I was expecting to return this amp because I doubted it would drive my speakers to the magic I fell in love with ... surprise!! It does an awesome job with the VS' Bass is back, stage has increased and holographic imaging is magnificent. Shoot, I may toy with adding a pair of Thiel CS 2.5's as an alternate set of speakers!! Thank you Crutchfield's and Jenny for incredible support and follow up, you guys are the best!
Purchased the NAD 375 BEE amplifier to drive a pair of low impedance (4 Ohm 86 DB Sensitivity) floor speakers. With is so much hyperbole from the exhalted extant, purchasing a better Amp can prove to be a daunting and expensive task. Based upon the laws of diminishing returns I sprang for this heavyweight, in return it rewards one with melodious dynamic unruffled power, fulfilling its purpose with aplomb. Exceedingly courteous purchasing experience from Crutchfield's

Soft Clipping: NAD's Soft Clipping circuit gently limits the output of the C 375BEE to minimize audible distortion when the amplifier is over-driven. While Soft Clipping can be left on at all times to reduce the likelihood of audible distortion from excessive volume settings, you can also turn the circuit off for critical listening if you prefer.
Bridgeable: The C 375BEE can be bridged to a single channel, more than doubling the power output. When bridged, the minimum recommended speaker impedance is 8Ω.
Tape Monitor: If you own a 3-head tape deck, the tape monitor loop allows you to monitor recording quality as the recording is made.
Phono Input: From the factory the C 375BEE has no phono input, but the optional PP 375 Phono Module can be installed, creating an input that will accept moving magnet or moving coil cartridges.
Front Input: A 3.5mm mini-jack input on the front panel is labeled MP (Media Player); there is also an RCA MP input on to rear panel which is automatically disconnected when the front panel input is used.
Pre-out/Main-in Loop: Factory jumpers connect the main amplifier input to the Pre Out 1 preamp outputs. This offers the flexibility of inserting an equalizer, surround processor (when using multiple amps), or another type of processor between the two stages.
Dual Preamp Outputs: The second set of preamps are convenient for bi-amping speakers or adding a powered subwoofer.
Remote Control: The SR 8 wireless remote will control the C 375BEE and NAD CD players and Tuners.

Wow. Spent a lot of time considering this purchase. I wanted to power speakers in my great room from various sources. Wanted plenty of power with decent sound and RS-232 control (this amp is located in the basement). Pretty good for the money. Checked off all the requirements on my list. [ Paul Sep 10, 2016 ]
clarence did a great job reviewing the technical solutions that were available based on my audio configuration. Clarence's Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=70 [ brian Feb 24, 2016 ]
reputation, quality build, continuous power ratings, drives 4 ohm speakers, have other NAD products that I like. [ David Feb 11, 2016 ]
Speaker manufacturer recommended [ Charles Dec 16, 2015 ]
Reviews. Good value. Power reserves. Sound quality. Ability to power low resistance speakers (planar-magnetic). [ ANN-KATRIN Dec 10, 2015 ]
YES, the only input I am using with this NAD amp is from a ASUS PCI-Express x1 XONAR ESSENCE STX/90 soundcard I installed in a Dell PC. It works excellent. [ TERRY K Sep 01, 2016 ]
Yes. I use it for hi res music but you must purchase the DAC module. [ Gregory Sep 01, 2016 ]
Yes... If you order the unit with the optional DAC module installed. You need the DAC... I opted for another manufacturer's external DAC component. That component has usb and tos-link interfaces with which to connect to your computer. It's pretty straightforward. Good luck [ Mike Sep 01, 2016 ]
NAD makes a add-on module, the MDC DAC 2, which can be installed in the back of the amplifier (you should have this done by the dealer at time of purchase). This module has a digital to analog converter and USB & optical digital inputs for connection directly to a computer. If you already have a DAC (such as a Dragonfly), you can run the output of that into one of the 7 line inputs on the amp. [ Steven Aug 31, 2016 ]
You will need a digital to analog converter (DAC) that can change your optical digital signals into RCA analog signals. [ CHIH May 17, 2016 ]
You are going to need a DAC. Most digital-analogue converter (DAC) have one or two optical ports (also known as optical drive or toslink). Plug the DAC, which you can also have your computer devices connected to, to the AUX analogue input (red and white RCA). I personally have the Cambridge DacMagicPlus....But, there are other brands out there just as good and slightly cheaper. After doing this type of connection, you will notice a superior sound coming out of your NAD. [ CRISTIAN May 17, 2016 ]
Dave I am afraid to say your question is way to technical to for me. I have a pair of Polk Tower RTiA7 speakers on Ch A, pair of Polk LSiM703 bookshelf spkrs on Ch B and a Polk DSW Pro660wi subwoofer. My system is in a raised center heighth barn 30ft x 40ft, 25 ft. high ceiling in the center. The sound is incredible, 60s 70s rock, jazz and blues. CDs Ipod and siruis XM feed the NAD. [ Frank Apr 21, 2016 ]
Not sure where you read that it put out the same power reguardless of load, but according to the NAD website it puts out 250, 410, and 600 watts of dynamic power at 8,4 and 2 ohms. All l can say is that I have a set or referbished Polk SDA 1b speakers that run about 2-4 ohms and the 375 will drive them to ear bleed levels. Even the little 326bee drives these low impedance loads very well. I'm very happy with both my NAD amps. [ DAVID L Apr 20, 2016 ]
It did not like my formula: I in amps (A) is equal to the square root of the power P in watts (W), divided by the resistance R in ohms (?) [ Robert Apr 18, 2016 ]
Not exactly sure but from what I understand if you run it at 4ohms speakers on an 8 ohm setting it will heat up the amp and that would apply if you mixed speakers of different resistances as electricity follows the path of least resistance. I believe it protects the amp form overheating and tripping an overheat, think of it as water the amps equals (flow) and is just a formula I (A) = ?P (W) / R (?) [ Robert Apr 18, 2016 ]
Yes,,,,,You have to use the pre-outs....You will noticed that it came with a circuit breaker or a bridge-like piece connected to it.....You have to remove it (but don't throw it away). If the subwoofer uses one cable, you will need a Y-RCA cable adaptor to connect on the NAD. If the subwoofer also uses RCA cable connectors, get a Y-RCA adaptor as well for it. But, you can easily figure out which is the best connection to go with. I am using two cables one for the red and another for the white RCA input on my NAD and Klipsch subwoofer. As I mentioned before, you will see pre-out 1 and pre-out 2 [ CRISTIAN May 17, 2016 ]
Yes [ Spencer Mar 21, 2016 ]
I checked the manual and there does not appear be a specific output listed for subwoofers. There are 2 sets out speaker outlets but do not know if this would work. I use a Bose system and the subwoofer and speakers are integrated as a "unit" requiring only the 2 (left and right) speakers be plugged in and the subwoofer works with them that way. I hope this helps. [ BENJAMIN T Mar 20, 2016 ]
There is not a dedicated sub output. I assume you are talking about a pre-amp level out to the sub. I run this amp with another power amp to another set of full range speakers so that takes the extra preamp output. I also run two powered subwoofers by splitting the output that goes to the built in amp of this unit. I send the each channel of the main pre-out to a splitterand one side of each splitter goes back into the Nad Amp and the other side goes to each subwoofer amp. This works just fine and allows me to balance the ouput to the second full range amp while running the subs. If you do not need to use the second amp output you could easily run your subwoofer off of the second pre-amp outputs. [ VINCENT Mar 18, 2016 ]
It cannot power both sets of those 4 ohm speakers at the same time. 8 ohm speakers are needed to do that. [ Paul Dec 09, 2015 ] Staff
The NAD 375 is far superior to that Sony. Stay with the NAD, but get a DAC [ CRISTIAN May 17, 2016 ]
After looking at the specs for your Sony 1050, I find it has two channel stereo line level outputs, and should work with the 375. But if you want the best performance from your 375, you'll want to use it in a stand alone two channel stereo system. I own a 375 and it's a phenomenal sounding stereo amp for music. Either way, you'll need separate speakers for your 375, and it sounds best with modern higher end models, and likes 4 ohm loads, to really come alive. [ DAVID L May 03, 2015 ]
