Onkyo TX-NR708

HDMI 1.4 with Audio Return Channel

The HDMI output incorporates the ARC “Audio Return Channel” function. If your TV is equipped with HDMI 1.4 ARC, this feature allows you to retrieve the sound from TV channels in the amplifier via the single HDMI cable connecting the 2 devices.

Audyssey MultEQ XT

Automatically measures and corrects distortions caused by room acoustics and calibrates speakers to achieve the best audio balance throughout the listening area.

Audyssey Dynamic Volume

Enjoy consistent volume when changing channels or audio sources.

Audyssey Dynamic EQ

Regardless of the listening volume, this technology maintains a coherent bass response, good balance, and well-perceived surround effects.
