Product Description
Amazon.com Product Description
Harman Kardon's AVR 635 7.1-channel audio/video surround receiver includes the company's latest features and technologies on top of near-universal surround-format compatibility. Internally, the receiver is engineered for extraordinary sonic performance, featuring a discrete-output amplifier section that delivers seven channels of high-current (+/- 50 Amps), ultrawide-bandwidth amplification--7 x 75 watts into 8 ohms, 20 to 20,000 Hz with less than 0.07 percent THD--in addition to state-of-the-art 192 kHz/24-bit audio digital-to-analog converters and a high-power Texas Instruments 32-bit DSP processor.

Take a closer look at the AVR 635's connections. You can also view the unit's front panel and remote control in detail.
The AVR 635's wealth of cutting-edge technologies also includes quadruple-crossover bass management, automatic digital input polling, video cross-conversion (which converts all composite- and S-video sources to high-resolution component-video), bidirectional RS-232 connectivity with software and firmware upgradeability, A/V sync delay, and a slot-mounted tuner that may be upgraded at a future date to accommodate HD Radio.

Surround sound features include Dolby Virtual Speaker, Dolby Headphone processing, and Dolby Pro Logic IIx processing (which provides an expansive, full-range 7.1-channel program from any stereo or 5.1-channel source). The receiver handles all other popular formats (including Dolby Digital EX and Dolby Digital 5.1), all standard DTS modes (including 6.1 DTS-ES Discrete, DTS-ES Matrix, DTS Neo:6, Cinema 6.1/5.1, and Music 6.1/5.1), and even the latest DTS 96/24 high-resolution audio technology. In addition, the AVR 635 provides HDCD (High-Definition Compatible Digital) processing to deliver the best possible CD playback quality from HDCD-encoded discs.

You also get Harman's proprietary Logic 7 audio for enhanced multichannel reproduction from both matrix-encoded and 2-channel recordings. The latest implementation of Logic 7 provides improved post-processing for the rear surround channels.

The receiver's many audio and video connections include three wide-bandwidth, assignable HDTV-compatible component-video inputs. The AVR 635 also features multiroom/multisource operation with independent, simultaneous playback of two program sources, assignable back surround amplifier channels, A-BUS connectivity, and a Zone II remote. The A-BUS Ready system simplifies multiroom connectivity without external amplifiers. It uses a standard Cat5/Ethernet cable to connect the receiver's rear panel in one room to a Harman Kardon AB 1 A-BUS-compatible amplifier/control module in a separate room.

Along with its extensive video connectivity, the receiver offers a array of digital and analog audio connections, including multiple coaxial and optical digital audio inputs and outputs. It sports both analog and digital front-panel inputs, 6-/8-channel direct audio inputs, and 7.1-channel preamp outputs to accommodate a DVD-Video, DVD-Audio, SACD, or universal player.

The AVR 635 is also among the first receivers to include EzSet/EQ, which provides automated system calibration and room equalization, which greatly simplifies installation as it improves system performance by tailoring the output of the receiver to your speakers, compensating for the effects of room acoustics.

The receiver's quadruple-crossover bass-management system lets you choose from six different crossover frequencies for the front L/R, center, surround L/R, and surround back L/R speakers. Most receivers and DVD players have far more limited crossover filtering or none at all. Moreover, you can set different speaker-size configurations for different AVR 635 input sources according to your needs.

You get a high-quality FM/AM tuner with 30 station presets and a Listener Preference System that lets you specify a surround mode according to the program source. You can also set speaker-channel levels for each program source and DSP format (for example, the subwoofer level can be set differently for multichannel movie viewing and 2-channel CD music listening).

Customer Reviews:

Sound off !.......2007-01-10

Read other reviews first, then ordered. Really think the negative reviews are picky. What matters is sound, and this unit is incredible. Friends now want to hang out and watch movies, games, or just TV. Easy hook up and the setup for the speakers was a hoot! Play the beginning of 'Pitch Black' and you'll never go back!

Very worthwhile, one of the better high end mass fi receivers.......2006-09-11

This receiver is much better than similar products I've owned from Sony ES, Pioneer Elite, etc. I'm fairly demanding of audio gear (my other rig is a single-ended triode tube rig with no preamp or anything else to pollute the sound running into some speakers that cost more than my last 4 cars combined, to give you an idea!). This isn't the ultimate audiophile rig, but it does have an exceptional combination of quality, features, and convenience. I'm very happy with the sound quality. The manual could be better, but it is usable. The ability to configure the receiver to drive another room was a key feature for me; my better half wanted to be able to hear music or TV in the study, and this does it nicely. The audio quality from the tuner is surprisingly good; it makes me think there's far less market opportunity for the new HD tuners than I'd thought previously, but I'll keep an open mind! Downside: there is noticable wavering as it tries to lock onto a video signal when I change channels in my vcr tuner, and I haven't noticed it doing anything (positive or otherwise) for the video signal, but I'm just using composite so it's not a fair test. I like the extensive back panel connectivity, too; it enables a lot of flexibility in how one uses this product. I also found the EZ set self equalization easy to use but far less than satisfying. I finally turned it off, and went manual. Overall, I have to say I'm very happy with this item, and I honestly don't know of a better integrated receiver solution.

Very Low.......2006-08-07

I purchased this expensive receiver from Amazon/Etronics in early July and received it with the volume light not working and immediately returned it by UPS. I have not heard one word from Etronics since. It's as if my receiver does not even exist. I have sent a dozen emails but never a reply.

Bang for the buck.......2006-07-15

I teamed this reciever with HKTS-14 and the door to the house rattles in the jamb when things in my movies blow up. The children outside get quiet. The clarity and thump are beautiful, both with the door and the AVR. My old man has the best Bose system you can buy and while it is no doubt great, I've had his system up all the way and this HK is more crisp and I swear louder. And let's not forget afterwords I had enough money left over for a nice steak dinner.
I researched HT systems for weeks and like the other reviews state, I don't think you'll see a better AVR for the price.
One caveat, if you're going to try running high-end HDTV exclusively with this you may want to look at a newer reciever. The highest quality video in is composite video and there was some uneven wash with the color when the video goes through the AVR. It comes and goes, but I don't think it was made for the 1024 x 768 generation of resolution. This is the only issue that would keep a person from wiring every house they live in for the next 10 years with this AVR. But then, you're not supposed to be able to keep up with technology. That's the point.
But back to the fun stuff: the thing weighs 50 lbs. That's magnet muscle to move sound. HK's Logic 7 beats all the rest of the various Dolby, et al., settings for movies, of which there are probably close to 40. Since not much comes made for 7.1 surround sound this is a wonderful feature as it in theory breaks 5.1 into believable 7.1. I don't doubt it with this reciever, but I haven't tried it. The more useful feature in my mind is the Zone 2 setting for the two extra 7.1 speakers which allow you to play source independent music in another room or the rest of the house. HK has some system (see the website) to put the Zone 2 AVR controls in the wall next to your light switch to run speakers outside, your bedroom, the kitchen, it's amazing. This is the kind of set up the rich kids have at their houses.
All in all I have had Sony and JVC (which was great for what it was), been very well acquainted with Yamaha, Denon, and Bose, and HK is the clear choice if you are beyond your piecemeal college system but haven't convinced your wife or yourself that $5,000+ is a reasonable amount to invest in a HT system.

So that is what music and movies sound like........2006-07-14

All of the reviews for this reciever were spot on. I have not fine tuned any of the adjustments yet and can already hear the difference in music and movies.
