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
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.
52. Functional Earth Terminal [SIGNAL GND]
Hum noise may be generated when external
equipment is connected to the unit. Connecting
this terminal to the functional earth terminal of the
external equipment may reduce the hum noise.
Note: This terminal is not for protective earth.
