IMAX Enhanced4 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.
THX Certified Select theater-reference sound
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.
Dolby Atmos Height Virtualizer
When playing any Dolby format, engaging Dolby Atmos Height Virtualizer4 enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers.
Dolby Atmos and DTS:X—setting sound free
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.
Ready for 4K HDR entertainment
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. Six 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 compliant5.
Rich analog sound from any digital source
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.
Whole Home Audio, just add speakers
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 outputs6, 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.
Versatile Zone 2/Zone B line-out
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.
Dynamic Audio Amplification
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.
New upgrades reduce noise and boost power
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 with AccuReflex
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.
Connections for custom installation
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.
Quad-core SoC supports 802.11ac Wi-Fi
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.7
