Dynamic Audio Amplification

Backed by 70 years of experience building high-grade audio components, the TX-NR676 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 210 W/Ch (6 Ohms, 1 kHz, 10% THD, 1 Channel Driven)/ 100 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. 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.

Powered Zone 2 and Zone 2 Lineouts

Powered Zone 2 speaker outputs let you send amplified network, S/PDIF, or analog audio sourced to a pair of speakers in another room. Line outputs can connect your home theater sources to a separate hi-fi system. Manage playback using Onkyo Controller.

Unlock Dolby Atmos and DTS:X Playback

Object-based soundtracks allow independently mixed sound to play through any speaker in your system. Effects move all around as they do in real life, so you experience 5.2.2-channel Dolby Atmos or DTS:X formats as the director intended. DTS Neural:X identifies spatial effects in multichannel soundtracks and upmixes for 3D playback, while DTS:X offers independent dialog volume control for movies. Dolby Surround is also included to upmix legacy multichannel formats for playback in a Dolby Atmos-enabled environment.

4K HDR, BT.2020, 4K/60 Hz, and HDCP 2.2 Support

Six rear HDMI inputs support pass-through of 4K HDR in both HDR10 and Dolby Vision formats; the BT.2020 4K Video Standard, 4K/60 Hz video playback; and HDCP 2.2 for premium content. Further, front HDMI is available for easy connection of a video camera or game console, while a rear Sub Output is ideal for connecting a projector.

Music Made Easy with Chromecast built-in*

Stream any music from your smartphone, laptop, or PC to the TX-NR676 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.

* Requires a future firmware update.

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.

Stream Anything with DTS Play-Fi*

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

* Requires a future firmware update.

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.

Wi-Fi, AirPlay, Spotify, and 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.

FireConnect Wireless Multi-room Audio

FireConnect mirrors network audio, analog, Bluetooth and USB sources connected to the TX-NR575 and allows distribution to compatible speakers and components in other rooms. Music selection, speaker grouping, and playback management across the home are built into Onkyo Controller app for iOS and Android.

Note: FireConnect is enabled with a firmware update. Sharing audio from external inputs depends on the model and is enabled with a future firmware update. Sampling rates of 44.1 kHz and 48 kHz are supported. FireConnect is a technology based on Blackfire provided by Blackfire Research Corp., USA.
