Onkyo Announces Two New AVRs (TX-NR535 and TX-NR636), Featuring Proprietary Room Correction Software and HDMI 2.0

Onkyo A/V Receivers are wildly popular within enthusiast circles and frequently find themselves on recommended buy lists due to their exceptional build quality, near-spec bench test results, and tech inclusions. It’s hard to find an owner that isn’t willing to boast about the brand and glowingly gush about a positive ownership experience. Today we’ll preview two new Onkyo AVRs, the 5.2-channel TX-NR535 and 7.2-channel TX-NR636, both of which feature HDMI 2.0 connectivity and a new proprietary room correction suite.


Recently, we previewed several Pioneer/Elite receivers featuring the industry’s first proclaimed HDMI 2.0 connections. With the 4K rush in full swing, consumers should expect most manufacturers to shift their attention to HDMI 2.0, especially because of HDMI 1.4’s incompatibility with future UHD technology. Though Onkyo’s marketing material falls short of screaming “HDMI 2.0” due to complicated marketing restrictions associated with HDMI number specifications, the TX-NR535 and TX-NR636 both feature HDMI support of 4K/60 Hz video and 2.35:1 widescreen formats. The NR636 adds 4K upscaling and HDCP 2.2 compatibility, a DRM copy-protection standard that will be used with future 4K studio releases, 4K streaming, and UHD broadcast material.

In a surprising change of direction, neither the TX-NR535 and TX-NR636 carry Audyssey room correction. Instead, they feature a new proprietary correction suite called AccuEQ, which is used with an included microphone to analyze speaker distance, type, crossover, volume, and room reflections. Onkyo says that AccuEQ is designed to bypass the mains, focusing its attention on the frequency response of the remaining channels for a resulting balanced sound. This change in onboard room correction tech will surely furrow some brows, as Audyssey has been a mainstay on Onkyo products for years. At this stage it’s unclear if Onkyo will shift away from Audyssey on all future AVR products.


Onkyo touts the units’ customized high-current power transformers, extra-large capacitors, and discrete low-distortion amps as being designed to manage impedance fluctuations and sudden dynamic gains (the TX-NR636 features Onkyo’s Three-Stage Inverted Darlington Circuitry for the front main and center channels). These features enhance the AVRs’ ability to deliver quality sound from HD audio encoded movie material (DTS-HD Master Audio™ and Dolby® TrueHD), and gapless playback of hi-res audio file formats such as 5.6 MHz DSD, Dolby® TrueHD, 192 kHz/24-bit FLAC and WAV, and ALAC to 96 kHz and 24-bit depth. On the TX-NR636, audio processing power has been upgraded from one to two 32-bit DSP engines.

The power rating for the TX-NR535 is rather modest, rated at 65 Watts (8 Ohms, 20 Hz-20 kHz, 0.7%, 2 channels driven, FTC), while the TX-NR636 is slightly beefier at 95 Watts (8 Ohms, 20 Hz-20 kHz, 0.08%, 2 channels driven, FTC).

Both models feature built-in Bluetooth, Wi-Fi, and DLNA 1.5 networking. This allows users to stream music stored on smart devices and through music services such as Spotify, Deezer, AUPEO!, and TuneIn. Onkyo says that support for Spotify Connect will be added later this year through an available firmware update.

Onkyo has included a rich connectivity array, including 6 rear HDMI inputs, one rear HDMI output (with 4K/60Hz passthrough), and one USB input (which supports most lossless audio formats on flash devices). The TX-NR636 adds one front HDMI input with MHL support, an additional rear HDMI output, a MM phono turntable connection, and dedicated powered Zone 2 terminals for multi-room audio.

The TX-NR535 will be available in March with a suggested retail price of $499 while the TX-NR636 will be available in April at a suggested retail of $699.

Interesting move on the room correction issue. Coming at at time when the best of Audyssey (XT32) is really good (at least that's my understanding). I wonder if perhaps they'll keep XT32 on AVRs whose price can pay for it, and abandon XT and 2EQ for their own algorithm on the less expensive models.

I guess this is what happens when you keep trying to cram more and more features into a receiver without raising the price, something has to give. Hopefully they will keep Audyssey around for their higher end models.

Obviously we'll have to wait for reviews, but I think this will end up being an upgrade (or equal to) comparative Audyssey offerings used in this price point...and the receivers, themselves, look like solid entries on paper.

I've asked Onkyo if they plan on extending this change up the chain, but haven't received an answer yet.

Re: Onkyo Announces the TX-NR535 and TX-NR636 AVRs, Featuring Proprietary Room Correction Software and HDMI 2.0

From a quick scan over of the features it seems that the 636 is a 626 without Audyssey and gains in the HDMI spec Dept as well as 1 addl HDMI input (front) and 1 addl analog input (back). I guess we will have to wait and see Onkyo's next move as well as stay tuned for reviews of the proprietary "room correction" they are employing now.

Dual DSP may be an audible benefit however it could also just be to cover the newer audio/video processing?

Amp sections appear to be same based on a max 6.3 amp draw and nearly identical in weight including dimensions.

I would have written less but I didn't have the time.

I agree, I dont see any advantage to Audeyssey 2EQ over what this new "propritary" room EQ is so this could even be a good thing if it actually does some work to the sub channel. XT is still very powerful so even that would be a shame to loose.

Home theater:
Onkyo 805, Yamaha YDP2006EQ, Samson Servo 600 amp
3 EV Sentry 500 monitors across the front, 4 Mission 762i's Surrounds, SVS PB13U sub, Panasonic BDT220, Harmony 1100, Nintendo WiiU
Panasonic PT-AE8000 on a 120" 2,35:1 fixed screen

Living room system:
Sherwood/Newcastle R972, Mission 765's, SVS SBS02's, A/D/S MS3u sub, Yamaha YDG2030EQ
Yamaha KX-393 Tape deck, CDC 805 CD changer, Panasonic BD60, Sony turntable PS-T20
Panasonic TC-P50ST60, HD-PVR & WDTV Live, Harmony 900

That idea of not EQing the left and right channels is interesting.

I wonder if AccuEq is better than Audyssey. Although the AccuEq sounds like bare bones from the description on what it does.

Re: Onkyo Announces Two New AVRs (TX-NR535 and TX-NR636), Featuring Proprietary Room Correction Software and HDMI 2.0

On their Facebook page, Audyssey CTO Chris Kyriakakis seemed a little bitter about the Onkyo announcement:

"Signs of the times: In a cost-cutting move, Onkyo has decided to go with the "free" EQ provided by their chip supplier. Sadly, you get what you pay for."

Ouch!

Bare bones indeed; not even close to what Audyssey does.
