​​THX Certified Select Theater Reference Sound

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. With 220 W per channel at your disposal, the TX-NR777 is ready to fill large spaces with heartpounding sound.

Made for Control and Custom Installation

The TX-NR777 includes system integration connectivity such as RS232 with support for 2-way communication with 3rd party home automation systems. An infrared (IR) input allows pass-through of IR signals to control other devices connected to the TX-NR777, such as a TV or Blu-ray player. The 12 volt trigger can be used to raise/lower a projection screen, power on/off an external amplifier or open/close the drapes with the touch of a button. A detachable power cord and an optional rack mount kit make for easy installation.

Dynamic Audio Amplification

Backed by 70 years of experience building high-grade audio components, the TX-NR777 amplifies accurate, noise-free signal processing with high-current power for dynamic speaker control. The result is pure, rich and authentic sound.

Onkyo's dynamic audio amplification delivers massive power at 220 W/Ch (6 Ohms, 1 kHz, 10% THD, 1 Channel Driven)/ 110 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.08% THD, 2 Channels Driven).

Smooth Analog Signal

Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the audio signal to its original form following processing. 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.

Powered Zone 2A/2B Audio Distribution

With a 5.2-channel layout in the media room, Powered Zone 2A/2B speaker outputs send amplified network, S/PDIF, and analog audio sources to pairs of speakers in other spaces. For 5.2.2 theater layouts, a line output is ideal for transmitting stereo sources available to the receiver to a hi-fi or amp and speakers set up elsewhere in the home. Multi-room playback is supported within Onkyo Controller app.

Note: Simultaneous playback of Zone 2A and Zone 2B is not supported, and speakers must be between 8–16 ohms impedance.

Unleash Dolby Atmos or DTS:X Home Theater

Object-based soundtracks allow independently mixed sound to play through any speaker in your system, moving above and around you with breathtaking realism. The TX-NR777 reproduces 5.2.2-channel Dolby Atmos or DTS:X formats, with AccuReflex correcting the phase of direct and indirect sounds for cohesive audio imaging with Dolby Atmos-enabled speakers.

Upmixing Solutions for Legacy Soundtracks

DTS Neural: X identifies spatial effects in multichannel soundtracks upmixes for 3D playback through object-audio-ready speaker systems. Dolby Surround also upmixes legacy sound formats so you can experience multidimensional playback of legacy sound formats in a Dolby Atmos environment.

Music Made Easy with Chromecast built-in*

Stream any music from your smartphone, laptop, or PC to the TX-NR777 with ease. Control playback with Chromecast enabled apps you know and love from your iPhone, iPad, Android phone or tablet, Mac or Windows laptop, or Chromebook.

*Available via firmware update.

HDR10, HLG, Dolby Vision, BT.2020, 4K/60 Hz, and HDCP 2.2

Six rear HDMI inputs support pass-through of HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision; the BT.2020 4K video standard; 4K/60 Hz video playback; and HDCP 2.2 for premium video content. Further, a front HDMI terminal is ideal for video camera connection, while the rear Sub Out is handy for projectors.

Onkyo Controller Supports Next Generation Network Audio

Onkyo Controller collects streaming services and network-attached audio into an intuitive smartphone app. Control playback, explore services, and distribute audio all over the home via FireConnect from one easy interface.

Wi-Fi, AirPlay, Spotify, Bluetooth

Selectable 5 GHz/2.4 GHz Wi-Fi assures stable connectivity so you can enjoy smooth streaming over AirPlay, the Spotify app, and the local network. Bluetooth wireless technology also provides quick and simple wireless streaming from your choice of music application.

Internet Radio and Streaming Services

TIDAL, Deezer, Pandora, and TuneIn are baked into the GUI, making it easy to select from a huge range of music and radio programs using Onkyo Controller.

384 kHz/32-bit Hi-Grade DAC

No matter what you're listening to, it will sound powerfully full, clean and clear. A premium-quality AK4458 digital-to-analog converter from Asahi Kasei implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of any audio format, including compressed, lossless, and hi-res audio.

AccuEQ & AccuReflex

AccuEQ conducts two measurements- one to set the level, distance and crossover for ALL speakers, including the subwoofer. Choose to include or bypass EQ measurement for front left and right speakers, and choose to automatically or manually set the EQ. Further, you can save your own manual EQ settings into three available presets.

AccuReflex technology aligns 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.
