*Enabled with a future firmware update.

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 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.

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.

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 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.

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.
*Note: Some countries or regions have regulations that affect wireless signal strength and the use of Wi-Fi channels.

Clarify voice dialog in-program instantly

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.

Buying a Onkyo Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it’s repackaged with accessories included. When you consider that a factory-renewed Onkyo product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Onkyo repair center (you can look-up locations online here or call 201-785-2600)

Onkyo, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened it must be resold as refurbished and can’t be resold as new again. The history and reason why a product was returned is not provided to us, thus we can’t provide any additional details regarding its past. All products are processed by Onkyo certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Onkyo Factory Refurbished" product.

Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
