Enjoy wireless audio streaming and object-based, multi-channel audio with the Onkyo TX-NR797 9.2-Channel Network A/V Receiver. The receiver features Dolby Atmos and DTS:X compatibility for object-based audio support. It outputs up to 100W of power per channel at 8 Ohms for room-filling sound. You can connect the receiver in a 9.2-channel setup or in a 5.2.4-channel setup for use in a Dolby Atmos or DTS:X object-based audio setup. AccuEQ sound calibration tailors the sound to your room's specific acoustics. Built-in Bluetooth connectivity lets you listen to music wirelessly from your favorite Bluetooth-capable devices.

The TX-NR797 is equipped with seven HDMI inputs and two HDMI outputs. One HDMI output supports ARC for the reproduction of display-based audio, such as your TV's built-in streaming apps. Onboard Wi-Fi and Ethernet connectivity allow you to connect the receiver to your network, enabling app control via the Onkyo Controller app or a variety of other network controllers. The on-screen display via HDMI helps you connect your receiver quickly and easily.

SMART AV Receiver

SMART AV Receiver integrates Amazon Music, Pandora, Spotify, TIDAL, Deezer, and TuneIn and supports multiroom audio with Works with Sonos (when connected to an optional Sonos Connect), Chromecast built-in (via a future firmware update), AirPlay 2 (via a future firmware update), DTS Play-Fi, and FlareConnect. Manage your music with just your voice via the Google Assistant (via a future firmware update) or Siri (with an Apple HomePod), enjoy the Sonos app, or use various Onkyo apps for simplified entertainment control around your home.

THX Certified Select Theater-Reference Sound

THX Certified Select helps ensure your home theater has the high-volume sound experience as a commercial movie theater. To gain certification, amplifiers must pass THX benchmark tests covering nearly every aspect of audio performance. THX Certified Select components suit rooms where screen-to-seat viewing is roughly 10 to 12' and room volume around 2000 cubic feet.

Dolby Atmos and DTS:X Sound

These two sound technologies mix audio in 3D space using object-based encoding as opposed to channel-based to help create the effect of sound moving all around you. Dolby Surround and DTS Neural:X find localization cues in legacy stereo or multichannel soundtracks and upmix them to simulate 3D audio.

Dynamic Audio Amplification

DAA features a High-Current Low-Noise Power Transformer, discrete amps, and capacitors. The circuit topology is designed to prevent phase-shift for enhanced sound clarity. High current through low impedance helps provide augmented control over the speakers for better detail resolution, faster dynamics, and more energy. Overall, this configuration can push 4 ohm loads with all channels driven.

Technical Design Enhancements Help Enhance Sound

The TX-NR797 has components designed to help control noise, boost driving power, and improve S/N performance. Its HDMI board features large, strong, well-finished grounds and short signal paths for clean and accurate A/V signals. Its SoC processor has its own board remote from audio signal paths to help reduce noise. Key aspects of the power supply line have been strengthened and upgraded to enhance driving power, which helps provide clearer separation and localization of instruments across a spacious soundstage.

Just Add Speakers for Whole Home Audio

Initiate playback of different audio source in up to three rooms at once from your compatible smartphone. The TX-NR797 has nine amplifier channels and two audio DACs supporting D/A distribution of different analog, network, Bluetooth, SPDIF, and HDMI audio sources (in select formats) via Zone 2 and Zone 3 outputs and supports a variety of speaker layouts, including 5.2.2-channel Main + Zone 2 or 5.2-channel + Zone 2 + Zone 3.

Quad-Core SoC with Wi-Fi 5 Support

The onboard quad-core System on a Chip (SoC) can perform multiple processing tasks at once. It provides network functionality with support for Wi-Fi 5 (802.11ac, 2x2 MIMO).

Zone 2 / Zone B Line-Out

The Zone 2 line-out lets you connect a component with an analog RCA line input to audio sources connected to the receiver, including digital audio via HDMI, optical, or digital coaxial. Zone B line-out is well suited for connecting your wireless headphone transmitter to enjoy your programming without disturbing anyone else.

Clear Dialogue with the Touch of a Button

The TX-NR797 features DSP-controlled Vocal Enhancer that identifies vocal frequencies and allows you to raise or lower them to your taste using the keys on the remote or via the tone controls on the receiver's front panel.

AccuEQ 9-Point Room Acoustic Calibration with AccuReflex

AccuEQ sets speaker parameters, such as size and distance, and sets their sound-pressure levels. It then selects the right subwoofer crossover setting and applies equalization to all your speakers. AccuReflex is designed to optimize object-based audio reproduction through Dolby Atmos-enabled speakers, resolving phase-shift caused by the path differences between directional and non-directional sounds. These features combine to help improve localization and provide a 3D soundstage with vertical movement and overhead dimensionality.

Connections for Custom Integration

The TX-NR797 features a 12V 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 rackmount kit is also available.

IMAX Enhanced, Available via a Future Firmware Update

IMAX Enhanced certification designates that the TX-NR797 meets certain audio and video performance criteria set by a committee of IMAX and DTS engineers and A/V technical specialists. These criteria include image, sound, scale, and content quality. Onboard IMAX calibrated modes are set and approved by Hollywood colorists to help provide enhanced picture and sound for HDR UHD content. This feature is scheduled to be made available via a future firmware update.

Virtual 3D Sound with DTS Virtual:X, Available via a Future Firmware Update

DTS Virtual:X is designed to create an immersive 3D soundfield from any speaker layout, regardless of whether height, surround, or rear speakers are installed. It uses DSP-based algorithms to place you at the center of a multidimensional soundfield with height and surround effects, and works in large or small speakers. DTS Virtual:X works in the 3D domain with DTS:X soundtracks, other DTS formats, and non-encoded stereo. This feature is scheduled to be made available via a future firmware update.

Dolby Atmos Height Virtualizer, Available via a Future Firmware Update

When playing any Dolby format, engaging the Dolby Atmos Height Virtualizer helps provide a more immersive listening experience by creating a virtual surround and height effect from traditional speaker layouts. This feature is scheduled to be made available via a future firmware update.
