5. Amplifier

9 channel Linear Class A/B Amplifier

Onkyo TX-NR797 features 9 channel power amplifier with Linear Class A/B design. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

Dynamic Audio Amplification: Onkyo TX-NR797 features Dynamic Audio Amplification which is Onkyo’s amplification philosophy that focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss. Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism - the “life” in music - is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction. Onkyo home theater receivers represent the culmination of almost 70 years’ experience in amplifier design. The unique elements of their amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.
WRAT (Wide Range Amp Technology): Onkyo TX-NR797 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.

THX Select™ (previously known as Select2) certified

Onkyo TX-NR797 is THX™ Select™ (previously known as Select2) certified. This means that it is made for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

6. Speaker Configurations

Onkyo TX-NR797's 9 channel amplifier can be assigned for different speaker configurations.

Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:

5.2.2, 5.2.4, 7.2.2 with internal amplifier.

DTS:X Configurations: The speaker configurations for DTS:X are the same as for Dolby Atmos:

5.2.2, 5.2.4, 7.2.2 with internal amplifier.

Configurations without height channels: There are also other speaker configurations available which do not include height channels:

5.2, 7.2 with internal amplifier.

2-ch Bi-Amp: Onkyo TX-NR797 allows you to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

7. Immersive Audio Formats

Dolby Atmos

Onkyo TX-NR797 supports Dolby Atmos with Surround Upmixer and Atmos Height Virtualization.

Surround Upmixer: If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.
Atmos Height Virtualization is a digital signal processing solution that leverages Dolby's deep understanding of human audio perception to create the sensation of overhead sound from the listener-level speakers.

DTS:X

Onkyo TX-NR797 supports DTS:X with Neural:X and Virtual:X.

Neural:X is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
Virtual:X bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
DTS Dialog Control: This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

IMAX Enhanced

Onkyo TX-NR797 is IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.

8. HDMI

Onkyo TX-NR797 features 7 HDMI inputs. It has 2 outputs: 1 Main and 1 Sub/Zone2.

4K/60Hz Passthrough: All inputs pass up to 4K/60p (RGB/YCbCr4:4:4) video signal.
4K Upscaling: Onkyo TX-NR797 can upscale 1080p to 4K from HDMI and analog sources.
Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Onkyo TX-NR797 will output them via HDMI. This means that you will need only one HDMI cable to connect to your TV.
BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35%.
HDCP 2.3 Copy Protection: All inputs and outputs are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
3D Ready: Onkyo TX-NR797 is able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Onkyo TX-NR797 supports HDR (high dynamic range) video formats such as HDR10, Dolby Vision and Hybrid Log-Gamma via HDMI ports. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.

9. Room Calibration

Onkyo TX-NR797 comes with AccuEQ Advance with AccuReflex™ room correction system and includes the calibration microphone.

AccuEQ: First, AccuEQ detects the presence of speakers and evaluates the impedance of each. Next, it pinpoints their distance relative to the main listening position using the mic and sets suitable sound-pressure levels. Then it selects the optimal crossover frequency so that deeper bass rolls smoothly off to the subwoofer. Finally, AccuEQ performs frequency response equalization based on room-acoustic and speaker data collected via microphone. The sound-field is now tailored around the listening position, resulting in a more immersive and realistic in-film experience.

10. Multi-zone Playback

Onkyo TX-NR797 offers multi-zone playback which allows you to play different input sources in 3 different rooms.

Zone 2

Powered Zone 2: You can use the unit's 2 amplifier channels by connecting Zone 2 speakers directly to the speaker terminals. The remaining 7 channels will be left for main zone amplification.
HDMI Output: Onkyo TX-NR797 offers HDMI output for Zone 2. This means that it can send two different HDMI signals to two displays.
Audio Line Output: If you have a dedicated integrated amplifier for Zone 2 you can connect it to the a/v receiver via line outs by sending fixed signal and then control volume on the Zone 2 amplifier.

Zone 3

Powered Zone 3: You can use the unit's 2 amplifier channels by connecting Zone 3 speakers directly to the speaker terminals. The remaining 7 channels will be left for main zone amplification.
