of ON/OFF, audio levels, active music channel, … and when later switched on, the Control Units power on with the same settings.
After a power loss, whether by disconnecting the power supply or because of a power failure, the status of the system once power is restored the Control
Units start up in their “ideal” state.
The audio inputs of each Control Unit can handle up to 6 music channel connections. The internal FM tuner is
set as channel 0. Channel #1 will synch up to the Master Unit’s FM tuner, which can be operated remotely from the Control Unit itself. The sound input
through the jack on the face of the Control Unit synchs up to channel #7.
