This 9.2-channel Onkyo SMART A/V Receiver™ plays the lead role in your whole-home audio experience. Works with Sonos, Chromecast built-in, AirPlay 2, and DTS Play-Fi® are enhanced by high-speed 802.11ac Wi-Fi® while speaker outputs with DACs can power D/A audio in three rooms. With nine channels of high-current power on tap, roll up the volume to THX® Certified Select™ reference level and wrap your family in 5.2.4 channels of Dolby Atmos® or DTS:X® sound, or feel IMAX® Enhanced content as the filmmakers intended. Dolby Surround® upmixes legacy sound for height-enabled systems while Dolby Atmos Height Virtualizer creates a 3D sound-field using horizontal speakers. DAA features an upgraded power-train while anti-noise refinements result in a wider soundstage. AccuEQ Advance 9-point calibration eliminates standing waves so audio is expressed naturally. All this and more helps the TX-NR797 shape entertainment to your life.
SMART AV Receiver is the heart of your home entertainment system. Access streaming content from Amazon Music, Pandora®, Spotify®, TIDAL, Deezer, and TuneIn and share sound as part of a multi-room system via Works with Sonos, Chromecast built-in*, AirPlay 2, DTS Play-Fi®, and FlareConnect™.
* The unit may automatically download and apply an Over-the-Air software update during setup.
The TX-NR797 can join your existing Sonos Home Sound
System, or be the start of a new one, by pairing it with a Sonos Connect*. The AVR ties into the Sonos ecosystem, waking, changing inputs, and playing at the desired volume on command from the Sonos app*.
*Sonos Connect sold separately. Sonos app is available free for iPad, iPhone, and Android™ at the App Store and Google Play. Please confirm device and OS compatibility before installation.
Stream any music from your smartphone, laptop, or PC to the receiver with ease. Control playback with Chromecast-enabled apps you know and love from your iPhone, iPad, Android™ phone or tablet, Mac or Windows® laptop, or Chromebook™. If you have a smart speaker featuring the Google Assistant, you can cue, play, and control music playback by voice.
Note: The unit may automatically download and apply an Over-the-Air software update during setup.
IMAX Enhanced* A/V receivers feature DTS:X sound technology optimized for the IMAX® signature experience, reproducing the full dynamic range of IMAX theatrical sound-mixes available with digitally re-mastered IMAX Enhanced content. A pre-set IMAX Mode reproduces audio at the highest levels and delivers IMAX Enhanced content as the filmmakers intended. IMAX Enhanced versions of a range of films, from Hollywood blockbusters to documentaries, will be released for 4K HDR streaming and Ultra HD Blu-ray™.
*Enabled with a future firmware update.
THX Certified Select guarantees the same reference volume level of a commercial theater in rooms where the viewing position is about 10-12 ft. from the screen. To gain certification for reference sound within strict THX® sound-quality parameters, receivers must pass 2,000 bench-tests in 75 categories covering 14,000 data points.
When playing any Dolby® format, engaging Dolby Atmos
Height Virtualizer* enables a more immersive listening
experience, creating a virtual surround and height effect from
traditional speaker layouts without employing additional
surround or height speakers.
*Enabled with a future firmware update.
Dolby Atmos® and DTS:X® map sounds in the movie to their corresponding positions in your room, so audio is localized or free move among your speakers and around the audience in sync with the action on screen. This 9.2-ch receiver expands object-based sound-field coverage with a 5.2.4 or 7.2.2-ch layout. Enjoy classic titles through your height-enabled system with Dolby Surround® and DTS® Neural:X upmixers for legacy soundtracks.
Enjoy support for HDR (High Dynamic Range) video including HDR10, HLG, Dolby Vision®, and BT.2020. The 4:4:4 color space is also supported. Seven HDMI inputs, ARC-ready MAIN OUT, and SUB OUT pass 4K/60p and HDR video from player to compatible TV and projector and all terminals are HDCP 2.3 compliant.
High-quality AKM 384 kHz/32-bit D/A conversion is enhanced by VLSC™ filtering (Front L/R channels), an original technology that erases digital noise arising from D/A conversion. Enjoy the purity of Hi-Res Audio sources, CD, and streaming music.
Orchestrate playback of different audio sources in up to three rooms at once from your smartphone. The TX-NR797 has nine amplifier channels and two zone audio DACs supporting D/A audio distribution via Zone 2 and Zone 3 outputs, including HDMI®/SPDIF/NET/Bluetooth®, and supports a variety of speaker layouts including 5.2.2-ch Main + Zone 2, or 5.2-ch + Zone 2 + Zone 3.
Note: HDMI and SPDIF support PCM audio only. Zone 2 HDMI audio available on inputs 1-3. Zone 3 supports analog/NET/Bluetooth.
Connect an audio system via analog RCA input to the AVR's Zone 2/Zone B line-out. In Zone 2 mode, you can play the same or different D/A sources (including SPDIF and HDMI) in either or both rooms at the same time. Zone B mode is an ideal match for a supported wireless transmitter. Listen to any source-including the TV-through wireless headphones. Perfect for midnight movies and TV.
Refined over 70 years to deliver emotion in high fidelity, DAA features a custom High-Current Low-Noise Power Transformer, customized capacitors, and discrete amp output stages. Unique topology prevents phase-shift while high current improves speaker control for true dynamic speed. Driving 4-ohm loads through all channels, DAA has power to move.
The TX-NR797 adds new refinements that control noise, boost power, and improve S/N performance. A new HDMI® board has shorter signal-paths and large, carefully finished grounds for clean A/V signals. SoC is isolated to reduce interference noise. The power-supply line is strengthened in pursuit of power and the results are evident in improved speed, force, and localization across an expanded soundstage.
AccuEQ Advance room acoustic calibration uses nine-point measurement to remove standing waves that occur when sound from the speakers resonates with sound reflecting off the walls, altering its natural expression. During the process, background noise is ignored to ensure accurate equalization. AccuReflex optimizes 3D sound reproduction through height speakers by resolving phase-shift. Enjoy a cohesive 3D soundfield in rooms of any shape or size.
The TX-NR797 features a 12 V trigger output for an external component and an IR input for remote-control range extension. It supports IP control, RS-232C, and OSD output for custom installers. An optional rack-mount kit is also available.
A powerful SoC (System on a Chip) processes multiple tasks at once. It evolves network functions and supports the latest high-speed 802.11ac (2x2 MIMO) specification while compatible with 802.11 b/g/n dual-band routers.
*Note: Some countries or regions have regulations that affect wireless signal strength and the use of Wi-Fi channels.
Vocal Enhancer solves inaudible dialog in TV programs and movies. DSP technology identifies voice frequencies so you can adjust them using remote-control keys or controls on the front panel.
