This unit has 6 discrete high quality amplifiers housed in one case. Each amplifier can be individually volume controlled and the source for each amplifier can be individually selected from one of four inputs. The in-wall control also displays the source selected on 4 LEDs. To switch between sources simply press the knob to step through the selections. There is also a built-in IR sensor on the control that relays signals from IR remotes back to the central amplifier unit.
Separate cable is run for the speaker signals.
Each of the 6 amplifiers is rated at 20 watts per channel. Variable loudness compensation boosts bass at low volumes to maintain a rich full sound at lower listening levels.
