Advanced Music Optimizer

Lossy files such as MP3 are convenient. However, signal data lost in the compression process results in comparatively low fidelity when played through a quality amp and speakers. Advanced Music Optimizer technology developed by Onkyo restores lost information for objectively better sound with these file types. Touch a key on the remote to enable Advanced Music Optimizer mode on a variety of input sources, including audio via Bluetooth technology and USB input.

Connect and power a media streaming device

A 5V /1A rear-panel terminal supplies power to selected HDMI media streaming devices, allowing you to affordably upgrade your home theater with on-demand network entertainment simply by adding one of these devices.
