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
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
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

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.
FireConnect™ Wireless Multi-room Audio
FireConnect™ mirrors network audio and external analog
sources connected to a master component—from streaming

speakers in other rooms. Music selection, speaker grouping,
and playback management across the home are built into
Onkyo Controller app for iOS and Android™.
Note: 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
