    Dynamic Audio Amplification

    Power your speakers like never before with Onkyo’s Dynamic Audio Amplification. Sound comes alive thanks to accurate, noise-free signal processing and hi-current power that dynamically controls your speakers for precise, authentic audioreproduction.

    Powered Zone 2 for Audio Playback in Second Room

    TX-NR656 has Powered Zone 2 capability to bring audio to a second room connected to your A/V Receiver. Now with dedicated Zone 2 DAC, you can bring Digital Audio input sources such as Spotify to a second room.

    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.

    Bluetooth / Wi-Fi® with Pandora, Spotify, and AirPlay

    The TX-NR656 has AirPlay, Wi-Fi and Bluetooth technologies built in. Stream virtually any audio from a smartphone, tablet or PC to your home theater for powerful sound. With Spotify, Pandora, and TuneIn built-in, you can select a station and search for music available on these services via the Onkyo Remote app on your phone. The free Onkyo Remote app puts a range of streaming options at your fingertips, from universal hi-res audio via network-attached devices to internet streaming services to music on your smartphone and tablet. Further, Tidal and Google Cast will be operable with an upcoming firmware update.

    384 kHz/32-bit Hi-Grade DAC

    A premium-quality AK4458 digital-to-analog converter from AKM unlocks the full potential of any audio format with unique low-distortion filtering technologies for clear sound.

    Easy Connection Guide on Back Panel

    A firmware update enables any audio source connected to the receiver—from vinyl to streaming audio—to be sent wirelessly via FireConnect™ to an optional speaker* placed anywhere in your home. Stable, fast, and easy to control with a mobile, it’s the smart way to set audio frefree.
