Harman Kardon engineers have built the AVR 3700 audio/video receiver for a premium home theater experience. No room is too big for this receiver, thanks to its high-current capability and 125 watts per channel. And speaking of the receiver’s channels: With 7.2 of them, the AVR 3700 empowers you to add a vertical dimension to the traditional five-channel surround-sound setup, with two front-height channels. The “.2” in “7.2” means that you can easily add a second subwoofer for ultimate bass in large listening rooms.

The AVR 3700 receiver can simultaneously play two different sound sources in two different zones. When you choose to connect your main system to 5.1 channels, you can use the receiver’s other two sound channels as an independent system in a second room. An included Zone II IR (infrared) remote control ensures that the people in the second zone can make their own choices without ever having to leave the zone.

Who knew that streaming audio could sound so amazing? The AVR 3700 lets you listen to almost any sound file stored on your home network. Access computer files wirelessly. Combine WiFi audio with AirPlay; you’ll make your iPhone, iPod touch or iPad sound better than you ever thought possible – and you won’t have to connect any additional cords or use an Ethernet cable.

Hear your networked media sources as never before in pitch-perfect surround sound. DLNA® 1.5 enables the AVR 3700 to stream audio from the devices on your home network using the receiver’s built-in Wi-Fi technology or an Ethernet connection, which allow you to enjoy audio and video at a quality that you would not have thought possible.

This free, downloadable software enables your AVR 3700 to enjoy DLNA compatibility with your Mac OS devices or Windows® operating system. And it helps organize and clean up the cover art on your music files.

The AVR 3700 uses a custom designed digital power supply that delivers the amplifier power and superior sound you expect from Harman Kardon without the need for hefty transformers. The result is the same power as conventional designs with a lower overall carbon footprint impact.

Harman Kardon’s EzSet/EQ system automatically sets key system parameters and fine-tunes the AVR 3700’s sound to your specific listening room with the press of a few buttons.

Your AVR 3700 doesn’t need a docking station. Instead, its front-panel USB port allows an easy-access connection point for compatble iOS devices. It even lets you access music stored on a flash drive. Furthermore, the included AVR remote gives you a convenient way to control many connected devices.

The AVR 3700’s 125-watt-per-channel amplifier is powerful enough for almost any system. But if you want even more power, the receiver has a full set of preamp outputs that let it serve as a fully-featured surround processor in combination with an optional, external power amplifier.

AVR 3700 is rated 3.090909090909091 out of 5 by 11.
Rated 5 out of 5 by from Superbly Powerful I purchased this about 3 months ago as a replacement for an AVR 8000. I too was concerned as to wether the newly designed amplifier in the AVR 3700 was still able to produce the same seamless power. It does. This receiver sounds just as beautiful with your favorite film as well as your favorite track. I cannot say enough good things. The on screen user interface is extremely intuitive and easy to use.

Rated 5 out of 5 by from Very good unit Hi, I have had this unit for about a week now and this is what i have learned so far. The good. Great looks plenty of power many options to customize your inputs outputs etc. very light unit compared to most harman gear i have owned preouts for all channels Remote is pretty good on this unit however when you use the light function it does not light up all the buttons ( 4 in the upper middle ) Wish list would have liked to be able to assign the unused surround channels to biamp my front speakers there is only 1 component input so make sure all your input gear can do hdmi after using the automatic setup bass was so heavy i had to manual adjust. not had to do that with my previous harman gear. would love to see app support like other devices for netflix hulu etc. no phono input no preout / power-in for seperate eq or processor ( probably not needed for most people ) Conclusion I would recommend this unit to any of my friends who want to spend $900+ on a very nice harman kardon AVR.

Rated 4 out of 5 by from Overall good value for the $ Purchased this in Sept 2015 to replace my older HK 247. It was an easy replacement, setup was simple. The first thing I noticed was much more detail in movie soundtracks, larger soundstage with more precise imaging. Audio dialog was less muddled and more forward. I could actually turn off the subtitles and lower the volume because I could hear the dialog very precisely for the first time since I have owned home theater equipment (more than 15 years). The difference was not subtle. Two things I don't like are the very bright volume nob, miss the old blue volume control and the lack of a switched plug on the back of the unit. Overall the features,quality, aesthetics and performance all offer good value for the $ in a very competitive market.

Rated 4 out of 5 by from Very Nice I picked it up a little over a year ago. When I removed it from the box, I remembered thinking that it felt a little light. I've got amps in storage that weigh more than 40 lbs., and I had this feeling that I may not have the power I like or need. Glad to say I was wrong; it does the job with ease. There are still things I'm learning about it; like I just decided to use the auto speaker setup mike last month, which turned out to be a huge mistake. Welcome to the 21st century; Airplay, Wi-Fi, control with iPad or phone, not to mention it's pretty nice looking in my audio rack. The only issues I have are ease of sound controls and inability to read the front buttons (should be lit, with everything else). Two thumbs up...

Rated 4 out of 5 by from Quality Reciever Love the look of this AVR. Was skeptical with the reduced weight and how it would compare to my old AVR354. It holds it own. Love the sounds and the power is there when needed. I run Klipsch speakers 5.1 and DefTech outdoor off zone 2. I have had zero issues with the power supply. Not sure how it would do with hard to drive speakers at unrealistic volume levels, but with my set up it has all the guts needed to do the job. The only thing I would like to see on this receiver is a little more room for speaker wire hook up. It is a struggle getting the wires in.

Rated 4 out of 5 by from Solid Performance, Software Bugs I purchased the receiver shortly after it came out. I have two cherry JBL Studio 880s attached to it and it really performs as well as I would have hoped. I purchased the receiver over the lower tier ones for the bells and whistles. Stuff like air play, wireless network connectivity and such. I'm really hoping for a software update however. During lengthy airplay streams over an hour or so the unit will occasionally drop connection with an airplay device, or while watching a movie on the computer while being connected over optical, the unit will put itself into sleep mode despite clearly being used and receiving a signal. All and in all I am satisfied, but these two particular issues detract from the premium experience I was expecting.

Rated 2 out of 5 by from Nice audio quality, poor 2-zone and settings I bought this AVR-3700 to make a 2 Zones system, with JBL 5.1 roof mount speakers for Zone 1, and Bose 251 speakers for Zone 2. Nice, until I started to setting it out: - Zone two audio source can NOT be a HDMI input. Only Analog inputs are accepted here. - Zone two has no high-pass filter settings available, and no gain/volume limit settings. - Cannot force the Zone-1 to use the 5 speakers when the source is 2-channel stereo. Denon receivers does this. Look's like some small software updates can fix this problems out, but the last software update for this is from 2014, and I bought it on 2015 Q4.

I have a Harman Kardon AVR 247.  Could you consider the Harman Kardon AVR 3700 a modern day, or up-to-date version of the AVR 247?

Asked by: Ed647
Yes, you can consider the AVR3700 can be considered the most updated version of our AVR's. The AVR3700 has a lot of function that the AVR247 does not have, i.e 7.2-channel wireless network-connected audio/video receiver with 125 watts per channel output. Apple AirPlay, High-Definition Dolby® and DTS® surround-sound decoding, multizone functionality and 4K video scaling.

Can I use this amp to connect my ffloor standing speakers bi-amp? With double wire! 

Asked by: Abdulrahman
Thank you for your question, you can use bi-amp configurations using external amplifiers but if you will be using the wire terminals on the back of the AVR 3700 you may not achieve the stereo configurations. you will then need to assign you will have to enable 5 stereo Channel, dolby digital will separate your audio.
