Dynamic Audio Amplification
Backed by 70 years of experience building high-grade audio components, the TX-NR656 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 170 W/Ch (6 Ohms, 1 kHz, 0.9% 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.
The TX-NR656 Powered Zone 2 brings audio to speakers connected to the receiver into a second room. With the dedicated Zone 2 DAC, you can send internet audio sources to your second listening zone.
Supports Dolby Atmos® up to 5.1.2 Channels
Dolby Atmos moves sound around you in three-dimensional space, so you feel like you're inside the action. The TX-NR656's Dolby Atmos decoding transports you from the ordinary into the extraordinary.
Sound designers and artists mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels. Additionally, the Dolby surround up-mixer processes content not mixed for Dolby Atmos to fill the flexible speaker layouts of a Dolby Atmos system.
DTS:X is an object-based surround sound technology that includes height channels for a fully-immersive listening experience. DTS:X provides listeners flexibility, immersion, and interactivity. You will be able to personalize your audio experience, for example, by turning up JUST the dialog within a mix. DTS:X allows you to customize to your room layout as well as control dialog and dynamic range.

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 (MP3, WMA, FLAC, WAV, OggVorbis, AAC, Apple Lossless, DSD 5.6 MHz, LPCM, and Dolby TrueHD).
AccuEQ & AccuReflex
AccuEQ conducts two measurements- one to set the level, the other to set the distance and crossover for ALL speakers, including the subwoofer. In the second round of measurements, your rooms sonic characteristics are evaluated. Using this information, AccuEQ is able to prevent standing waves from forming by adjusting frequency response. 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. The new AccuReflex technology aligns the phase of upfiring "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.
FlareConnect Wireless Multi-Room Audio
FlareConnect mirrors network audio, analog, Bluetooth and USB sources connected to the TX-NR656 and allows distribution to compatible speakers and components in other rooms. Music selection, speaker grouping, and playback management across the home are built into the Onkyo Controller app for iOS and Android.
