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.
