51. Local Audio Control Input Terminals

[LOCAL AUDIO IN 1/IN 2]

Audio signals fed to these terminals are broadcast

to only the zones that this unit covers.

Each terminal is equipped with a control input,

which allows local broadcasts to be made.

It is possible to isolate the control input from this

unit by changing the internal jumper setting. (See

p. 63

for details.)

Input "IN1" has a higher priority than Input "IN2."

If the control input terminal of "IN1" is activated

while broadcast is made through the "IN2," the

broadcast is interrupted and changed to the

broadcast through the "IN1."

the local input has a lower priority than the BGm

or general-purpose sound sources. Activating the

emergency broadcasts to a part of zones where

local broadcasts are currently in progress causes

all local broadcasts to terminate.
