Product Information

THX-Certified Select Receiver Fills Big Rooms with Sound

With 220W per channel on tap, the TX-NR777 has ample power to push a full-scale speaker system to THX Theater Reference levels without breaking a sweat.

High-current amps control speaker drivers for accurate reproduction of Dolby Atmos and DTS:X, with VLSC cleansing signals of subtle noise to make Hi-Res Audio even more transparent. Streaming network audio, along with external analog sources, is sharable to NCP-302 wireless speakers over FireConnect powered by Blackfire. Music selection and multiroom management is centralized in Onkyo Controller, or stream music over AirPlay, DTS Play-Fi, or Chromecast built-in. Elevating the 4K Ultra HD experience with object-based audio, the TX-NR777 also supports Dolby Vision, HDR10, HLG (Hybrid Log-Gamma), and BT.2020 pass-through for the ultimate in sound and vision.


  • THX-Certified Select reference sound
  • Supports 5.2.2-channel Dolby Atmos and DTS:X playback
  • Dynamic audio amplification with 4-ohm speaker driving capability
  • 384 kHz/32-bit DAC and VLSC filtering for superior clarity
  • Ready for Chromecast built-in and DTS Play-Fi platforms
  • 5GHz/2.4GHz Wi-Fi, AirPlay, Spotify, TIDAL, Deezer, Pandora, and TuneIn

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

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 and upmixes for convincing 3D playback through your object-audio-ready speaker system. Dolby Surround remixes legacy sound formats for multidimensional playback 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.

Stream Anything with DTS Play-Fi

DTS Play-Fi is a wireless protocol that works with almost any audio app on mobiles and PC. Flick whatever’s playing to the receiver, even different sources to different components at the same time.

FireConnect Wireless Multiroom Audio

FireConnect mirrors network audio and external analog sources connected to a master component—from streaming services to vinyl records—on FireConnect-compatible speakers in other rooms. Music selection, speaker grouping, and playback management across the home are built into Onkyo Controller app for iOS and Android.
