The latest, convenient HDMI technology

With HDMI, you can use this receiver to watch 3D video from a Blu-ray disc. Other convenient features include an Audio Return Channel for TVs with DVD player or Tuner built-in, for example, and Standby pass-through.

Connect your portable device

If you have a mobile device to play audio from, simply connect it to the receiver using the 3.5mm mini-jack on the front panel.

Intelligent speaker calibration

Surround speakers can hardly be ideally positioned. MCACC therefore analyses the existing sound field using a microphone (included), just like a sound professional, and adjusts the sound timings to precision-tune the system to your room.
