About the Onkyo TX-NR797 (2019 model)
Fun for the whole family
Fun for the whole family
My living room's home theater system spends most of its time belting out high-octane movie soundtracks while my subwoofer thumps its floor-shaking approval. But every now and then, my four-year-old wants me to stream "Baby Shark" while she runs around chomping her sharky jaw-hands. At the heart of all of this fun is an Onkyo home theater receiver.
That's the beauty of a state-of-the-art model like the TX-NR797 — it excels at reproducing high-quality audio and video for movies and TV shows. But packed inside are a ton of wireless music options that everyone in the family can enjoy. And with multi-zone capability, this receiver can handle movie night in one room, and play music in another at the same time.
The TX-NR797 is packed with wireless music streaming options that make listening to your favorite tunes a breeze.
Key new features for 2019
The TX-NR797 retains the entire feature set of last year's model, and also offers some fun new additions. Apple AirPlay 2 lets you stream content directly from your iPhone® or iPad®. You can also ask Siri to play songs from Apple Music.
The '797 sports a speedy new quad-core networking processor, an improved on-screen display, and a new remote control to help make your experience smoother and more enjoyable.
A free future firmware update will even add IMAX® Enhanced, a new audio decoding feature that reproduces the full dynamic range of specially encoded IMAX movie soundtracks from compatible sources.

32-Bit Architecture: The Onkyo TX-NR797 AV receiver utilizes 32-Bit architecture with Dual 32-Bit DSP Engines and a 384kHz/32-Bit Hi-Grade DAC for exceptional sound quality. The Onkyo TX-NR797 employs powerful and highly accurate 32-bit DSP (Digital Signal Processor) engines for better surround sound reproduction. The AV receiver also incorporates a premium-quality AK4458 digital-to-analog converter from Asahi Kasei for all channels. This 384kHz/32-bit DAC implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of of your high resolution multichannel audio formats - including Apple Lossless, FLAC, WAV, DSD, LPCM, Dolby TrueHD and DTS-HD.
Advanced Circuitry: The Onkyo TX-NR797 incorporates a variety of advanced circuitry to eliminate jitter & distortion for cleaner, clearer sound reproduction.
- Vector Linear Shaping Circuitry (Front Channels Only): Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the signal in its original form following processing. Unlike conventional filters, VLSC removes pulse noise generated in D/A conversion, allowing the sound wave to be reproduced with extremely high fidelity for a smooth analog signal. The signal's data is converted between sampling points and joined with analog vectors in real time to produce a smooth output wave form. The result is a virtually noiseless, smooth, analog signal that brings out even the most subtle of nuances in music sources.
- PLL Jitter-Cleaning Circuit Technology: PLL (Phase Locked Loop) jitter-cleaning circuit technology reduces jitter by comparing the input and output phases of the digital signal and creating an accurate clock waveform. This enhances the precision of digital signal processing and noticeably improves audio quality. Jitter-cleaning technology works for S/PDIF audio signals only.
AccuEQ Advance Calibration w/ AccuReflex: The TX-NR797 incorporates AccuEQ Advance calibration technology and comes with an auto calibration microphone. AccuEQ Advance calibration technology reveals the true potential of your speakers by eliminating standing waves from your listening space using multipoint measurements (up to 9-points). These acoustic peaks distort the audio image and prevent your loudspeakers from voicing the sound as their designers intended. AccuEQ Advance also utilizes Partial Band Equalization and only corrects frequency response below a certain point, leaving high-order harmonics untouched - so your speakers are free to reproduce the emotion in the recording faithfully and naturally.
- Speaker Measurement: The first-round of AccuEQ Advance measurements set the distance, sound pressure level, and crossover of your speakers. Distance and level calibration ensure all channels are treated equally. Crossover measurement selects the correct point to roll off low-frequency sound to the subwoofer for seamless speaker integration.
- Room Measurements: In the second round of AccuEQ Advance measurements, your room's sonic characteristics are evaluated. Using this information, AccuEQ Advance is able to prevent standing waves from forming by adjusting frequency response. AccuEQ Advance even listens and compensates for the subtlest background noise (such as the hum of an HVAC) to ensure a higher degree of measurement precision.
- AccuReflex Measurements: AccuEQ Advance also incorporates AccuReflex technology to align the phase of up-firing "height" speakers with the sound coming directly from your other speakers. Any delay is resolved so that everything arrives at your ears at the same time. The result is cohesive reproduction of object-based soundtracks.
Note: You can choose to bypass AccuEQ Advance for your front speakers or all speakers, and manually set the distance, crossover, EQ, and level of each speaker.
IMAX Enhanced Technology (via firmware update): Get the most premium at-home entertainment experience with IMAX Enhanced; the latest technology program from IMAX that sets a new standard for image, sound, scale and content quality. This new certification and licensing program combines IMAX digitally re-mastered 4K HDR content and DTS audio technologies to offer a new level of quality in immersive sight and sound experiences in the home. IMAX Enhanced lets you experience premium content digitally remastered by IMAX, so you can watch the highest-quality 4K movies with immersive audio delivered by DTS. Not only will IMAX Enhanced content look and sound amazing, but other audio/video content will also look and sound great too.
- Remastered 4K/HDR Video: It utilizes a sophisticated, advanced algorithm designed to produce the highest-quality, sharpest 4K HDR images. This advanced process accurately reduces noise and grain under the filmmaker's guidance to best optimize the content for a much higher quality, higher brightness 4K HDR display format. Select IMAX Enhanced titles that were shot with IMAX cameras or specially formatted for IMAX theatres will also include an expanded aspect ratio for the film's home release to show your more picture on your TV. IMAX Enhanced certified TVs must be at least 65" with support for HDR10 and dynamic, as well as specific calibration, resolution, color, brightness, contrast, and scale of image capabilities.
- Remastered DTS:X Audio: IMAX and DTS will also partner with award-winning Hollywood sound mixers to use a special variant of its DTS:X codec technology integrated in home audio equipment to deliver an IMAX signature sound experience that is dynamic, immersive, theatrical, and powerful. IMAX Enhanced supports both 5.1 and 11.1 formats, but the recommended speaker layout for an IMAX Enhanced system is 7.2.4 with seven horizontal speakers, two subwoofers and four height speakers; 5.1.4 is the minimum layout for IMAX Enhanced. However, due to various constraints you may opt to install only a 5.1ch speaker system. In such cases, DTS Virtual:X is required to properly render and remap audio to the available speakers.
- Available IMAX Content: IMAX is working with its global studio and other content partners to build a steady stream of IMAX Enhanced versions of movies and other programming using the newest, proprietary post-production process developed by IMAX. IMAX will be announcing and releasing IMAX Enhanced versions of a wide range of films both for 4K/HDR streaming and Ultra HD Blu-ray Discs.
- To take full advantage of IMAX Enhanced, you need an IMAX Enhanced certified 4K/HDR TV (65"-up) or Projector and an IMAX Enhanced certified DTS:X enabled AV receiver or soundbar.
- IMAX and DTS developed the IMAX Enhanced program out of their decades of combined expertise in image and sound science to make it easier for consumers to select the products and content that will deliver the highest-quality, sharpest 4K HDR images and powerful, immersive sound at home.
- To qualify and carry the IMAX Enhanced logo, the highest-end TVs, AV receivers, projectors, and soundbars must meet stringent performance standards established by IMAX, DTS and Hollywood's leading colorists in order to create a consistent and higher bar for image and sound performance on premium devices.
THX Certified Select: THX Certified Select guarantees the same high-volume sound you experience at a commercial theater in your home. To gain certification, amplifiers must pass the industry's most severe bench-tests covering every aspect of audio performance to satisfy THX requirements. THX spends 40-60 hours on 2,000 bench-tests in 75 categories covering 14,000 data points ensuring that the receiver is capable of meeting rigorous audio and video performance standards for reference level, distortion-free playback. THX delivers superior sound quality for movie, music, and gaming soundtracks through the use of the following advanced technologies and listening modes.
- ASA (Advanced Speaker Array): ASA is a technology patented by THX to provide a broad surround sound experience by adjusting the side and back surround speaker sounds respectively. When installing the surround back speakers, first select the distance between the two surround back speakers in the THX Audio settings. This setting optimizes the surround sound environment.
- Adaptive Decorrelation: In a movie theater, a large number of surround speakers help create an enveloping surround sound experience. If a home theater only has two sidewall surround speakers, the surround speakers may sound similar to headphones lacking spaciousness and envelopment. Surround sounds will also collapse toward the closet speaker as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround channel's time and phase relationship with respect to the other surround experience as in a movie theater using only two rear speakers.
- RE-EQ & Timbre Matching: Many movie soundtracks are mixed in studios for playback in large cinema auditoriums with an array of speakers. When played on home systems, they may appear abrasive and edgy. Re-EQ establishes a more accurate tonal balance when enjoying movies in your home. Your ears hear different tonal qualities in sounds coming from different directions. Timbre Matching restores the frequency balance between your front and surround speakers ensuring seamless and smooth panning between the front to back of the room.
- Boundary Gain Compensation (BGC) & THX Loudness Plus: Sitting near a wall may result in distorted bass response. BGC corrects the way low frequency sound is perceived when seated near a wall. This results in a more accurate bass response. THX Loudness Plus is a volume control technology that automatically adjusts the front-to-back speaker level relationship as you turn the volume down. With THX Loudness Plus home theater audiences can now experience surround sound at any volume level.
- Listening Modes: Choose between 4 THX Listening Modes - THX Cinema, THX Game, THX Music, and THX Surround EX. THX Cinema recreates the ambiance of the movie theater by positioning the 5.1, 7.1and immersive mixes to submerse you in the movie's soundtrack. THX Game distributes the sound effects and dialogue generated by the game engine by placing the audio from a 5.1, 7.1 or immersive mix to the appropriate "action" location - creating 360-degree gaming experience. THX Music emulates the original studio environment for the 5.1, 7.1 or immersive mix for an accurate and increased sense of spaciousness and localization - placing you directly in the recording session. THX Surround EX decodes the third surround channel from the traditional two surround channels to create a more immersive entertainment experience.
Note: THX Certified Select is suitable for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

Immersive Surround Sound: The Onkyo TX-NR797 AV receiver goes beyond regular surround with the latest immersive surround sound formats, including Dolby Atmos and DTS:X. The Onkyo AV receiver also supports Dolby Surround & DTS Neural:X to enhance 2-channel and multichannel decoding formats. In addition, it supports Dolby Atmos Height Virtualization (future firmware update) and DTS Virtual:X for multi-dimensional sound from a standard 5.1 or 7.1ch setup.
- Dolby Atmos: Dolby Atmos surround sound technology dispenses with channel-based coding in favor of more advanced object-based coding, giving the soundtrack designer the ability to precisely place sounds anywhere in the 3-dimensional space. The TX-NR797 has the processing power to run a more enveloping 7ch or 9ch Dolby Atmos layout using 5.1.2, 5.1.4, or 7.1.2 configurations utilizing ceiling mounted or Dolby Atmos-enabled speakers (sold separately).
- Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch or multichannel movie soundtracks using your existing 5.1ch, 7.1ch, or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
- Dolby Atmos Height Virtualization (via available firmware update): Dolby Atmos Height Virtualization provides immersive audio without height-channel or overhead speakers, creating virtual height effects in a 5.1ch, 7.1ch or 2.1ch speaker arrangement. Dolby Atmos Height Virtualization applies carefully designed "height-cue" filters to the overhead audio components of your content's soundtrack before they are mixed into your loudspeakers to create the sensation of sound above you.
- DTS:X: The latest immersive surround sound system, DTS:X features object-based audio coding that lets the soundtrack designer place sonic elements anywhere in the 3D acoustic soundspace, and provides for overhead speakers to deliver a stunning surround sound experience. Along with DTS:X decoding, the TX-NR797 features DTS-HD Master Audio decoding and other DTS audio technologies.
- DTS Neural:X: DTS Neural:X is an advanced spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. DTS Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.
- DTS Virtual:X (via available firmware update): DTS Virtual:X bridges the gap between DTS:X and the reality of so many consumers' homes that cannot accommodate overhead speakers, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. DTS Virtual:X can be used with any content (from 2ch to 7.1.4ch soundtracks), while delivering virtual height & virtual surround processing based on psychoacoustics (not reflective surfaces).
Onkyo Original DSP Modes: Onkyo's Original DSP Modes, combined with Dolby Digital & DTS processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. You can choose from the following:
- Orchestra: Suitable for classical or operatic music. This mode emphasizes the surround channels in order to widen the sound image, and simulates the natural reverberation of a large hall.
- Studio-Mix: Suitable for rock or pop music. Listening to music in this mode creates a lively sound field with a powerful acoustic image, like being at a club or rock concert.
- TV Logic: Suitable for TV shows produced in a TV studio. This mode enhances the surround effects to the entire sound to give clarity to voices and create a realistic acoustic image.
- Unplugged: Suitable for acoustic instruments, vocals and jazz. This mode emphasizes the front stereo image, giving the impression of being right in front of the stage.
- Multichannel (Multich)/Game: Multichannel mode is suitable for playing sources recorded in multichannel PCM. The receiver also offers four different Gaming modes - RPG, Action, Rock, and Sports.
- Stereo/All Channel Stereo (AllCh Stereo): In Stereo mode, sound is output from the front left and right speakers and subwoofer. In All Channel Stereo Mode, stereo sound is output from all speakers - ideal for background music.
- Mono/Full Mono: In Mono mode, when the input signal is analog or PCM, the left and right front speakers output the sound in monaural. In Full Mono mode, all speakers output the same sound in mono, so the sound you hear is the same regardless of where you are within the listening room.
- Theater-Dimensional (T-D): In this mode, you can enjoy a virtual playback of multichannel surround sound even with only two or three speakers. This works by controlling how sounds reach the listener's left and right ears
Direct Mode: The Direct listening mode can be selected for all input signals. In this mode, processing that affects sound quality is shut down, and sound closer to the original is reproduced. The sound is reproduced with the soundfield based on the number of channels in the input signal. For example, a 2ch signal is output only from the front speakers. Note that other sound adjustments are not available when this mode is selected.
Audio Enhancements: The Onkyo TX-NR797 receiver provides various audio enhancements to deliver a high-quality listening experience every time.
- CinemaFilter: The CinemaFilter softens overly bright movie soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your home theater) with lots of soft seats and thick curtains on the walls. Home theater settings often lack these high frequency absorbing wall treatments, making the soundtrack sound too bright. CinemaFilter accounts for this and for many movies sounds more natural at home.
- Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function only works with PCM digital audio input signals with a sampling rate below 48kHz, analog input signals, and Bluetooth audio.
- Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High. This feature only works with Dolby Digital Encoded software and the depth of the feature will vary based on the individual software package.
- Stereo Assign Mode: At the touch of a button, Stereo Assign Mode switches playback from your Front speakers to either the Surround, Surround Back, or Height speakers. This mode is deal for ambient listening, such as background music, or any time you want to create a relaxing atmosphere.
Dialog Improvements: The receiver offers a variety of dialog enhancements that make it easier to hear dialog and vocal when listening to movie and music soundtracks. The Vocal mode emphasizes movie dialog and music vocals, so you can hear them more easily amongst the movie effects and musical instruments. The Vocal mode can be set from 1 (low) to 5 (high). Dialog Control allows you to boost the dialog in a DTS:X soundtrack to make dialog more intelligible in noisy environments. Center Spread expands the center channel signal to left and right front speakers to create a wider frontal audio image for the listener, when in Dolby Surround mode.
Bass Management: The Onkyo AV receiver offers Phase-Matching Bass, Double Bass, and Tone Control to get the most bass impact out of your system. Onkyo's Phase-Matching Bass optimizes low frequencies while preserving mid-range clarity. This means that powerful bass plays back with clear vocals; it doesn't overpower them. You can also activate the Double Bass function in order to boost bass output even more by feeding bass sounds to the front left/right speakers, center-channel, and powered subwoofer. In addition, you can independently adjust the Bass (20Hz) and Treble (20kHz) of the receiver's Front L/R channels from -10 to +10 dB.
ARC (Audio Return Channel): The receiver's main HDMI monitor output features ARC (Audio Return Channel). This feature allows audio to be sent from your compatible TV to your receiver through the same HDMI cable already being used to send audio and video to your TV. This eliminates the need for extra cables connected to your television. The receiver's sub HDMI out does not support HDMI.
Volume & Level Setup: The Onkyo AV receiver provides the following volume & level settings.
- IntelliVolume: With IntelliVolume, you can set the input level for each input (-12 to +12dB) selector individually. This is useful if one of your source components is louder or quieter than the others. This function does not work in Zone 2 and Zone 3.
- Maximum Volume: Use this feature to set the receiver's maximum volume level for the Main Zone, Zone 2, and ZoneThis feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from 50-99, or Off (disabled).

HDMI 2.0b: The Onkyo TX-NR797 has seven HDMI 2.0b inputs (6 rear/1 front) and two HDMI 2.0b outputs. The dual HDMI outputs can simultaneously output the same audio/video signal to two TVs, or you can assign the second HDMI output to Zone 2 to display a different HDMI source (1-2-3 inputs) in another room; video is output at the resolution supported by both TVs. Thanks to its HDMI 2.0b specification, the receiver can support 4K/60 Hz Ultra-HD video, HDCP 2.2 compatibility, 4:4:4 color sub-sampling, High Dynamic Range (HDR), and BT.2020 Wide Color Gamut.
- 4K/60Hz w/ Upscaling: The TX-NR797 supports up to 4K (3840x2160 or 4096x2160 pixels) video @ 60 frames per second on all of its HDMI inputs and output. It will also pass a 480p, 720p, 1080i, or 1080p video signals via HDMI (not compatible with 480i video signals). The receiver can even upscale 1080p HDMI input video sources to 4K Ultra HD (3840x2160 pixels) through its main HDMI monitor output (the sub HDMI output does not support upscaling).
- HDCP 2.2 Compliance: The receivers HDMI inputs and HDMI monitor outputs support the latest HDCP 2.2 certification, which fully complies with the latest copyright protection standard for 4K video transmission. The unit will offer HDCP 2.3 support via a future firmware update (no ETA).
- 4:4:4 Color Subsampling: The receiver's HDMI inputs and HDMI monitor outputs support RGB/YCbCr 4:4:4 (8-bit), YCbCr 4:2:2 (12-bit), and YCbCr 4:2:0 (8/10/12-bit) color subsampling in 4K @ 60Hz/50Hz; or RGB/YCbCr 4:4:4 (8/10/12-bit) and YCbCr 4:2:2 (12-bit) in 4K @ 24/25/30Hz. With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail.
- Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
HDR (High Dynamic Range): HDR (High Dynamic Range) video provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. This receiver supports two HDR formats - HDR 10, Hybrid Log-Gamma (HLG), & Dolby Vision.
- HDR 10: HDR 10 is an open standard and currently the most popular HDR format on the market. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
- Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
- Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata technology which sets individual color and brightness levels for each and every scene. Dolby works directly with filmmakers at major Hollywood studios to create superior HDR video masters of blockbuster movies.
Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K/HDR performance.
Analog Video Inputs w/ HDMI Conversion: The receiver features two composite video inputs and one component video input which support 480i video signals only (the component video input is not capable of high-definition video). All analog video input signals are converted to digital and sent via HDMI to your TV at 480i (no upscaling). Only the receiver's main HDMI monitor output supports analog-to-HDMI video conversion (the receiver's sub HDMI monitor output does not support this feature).
Other HDMI Features: The TX-NR797 AV receiver's HDMI connectivity also offers 3D video pass-through, Deep Color & x.v. Color support, as well as an auto LipSync function.
- Deep Color & x.v.Color Support: The AV receiver supports Deep Color and x.v.Color content, which can display a larger color range than standard-definition schemes. The result is a more lifelike, vibrant picture
- 3D-Ready: All HDMI jacks will accept 3D video from your 3D-ready Blu-ray player and output the video signal in 3D to your 3D-ready flat-panel television.
- AV Sync: The AV Sync feature can automatically synchronize HDMI audio and video (for any HDMI jack) that has gotten out of sync due to the complex digital video processing being performed by your HDMI-compatible TV. With AV Sync, the audio delay required to synchronize the audio and video is calculated and applied automatically by the AV receiver. You can also manually correct the audio delay using AV Sync.
HDMI Through: When enabling the HDMI Through function, regardless of whether the AV receiver is "O" or in "Standby", both audio/video streams from an HDMI input will be output to your television, via the receiver HDMI monitor output. You can select between three HDMI Through modes.
- Auto: Detects the signal and automatically selects the input sources.
- Source: Selects the HDMI input source for which the HDMI Through function in enabled.
- Last: The HDMI Through function is activated on the input source selected at the time of setting the AV receiver to the "standby" mode.
Video Select: It is possible to play audio and video from different sources simultaneously. For example, you can play audio via Bluetooth and video from your BD/DVD player. This function is only effective when an input with audio only (Network, Bluetooth, or Tuner) has been selected initially.
