SCHEMATIC

The Rolls PA66 assigns a balanced microphone signal to up to six zones of a multi-zone sound system.

The zone that the microphone signal will be sent to is se- lected by pressing the corresponding front panel switch.

Each PA66 zone output has a contact closure terminal set that shorts together when the corresponding front panel switch is pressed. This feature is designed for paging ampli- fiers with relay switches inside that mute background music while paging.

The PA66 can be powered by any source of 9 to 20 VDC or

VAC, with at least 20mA of current available.
