●Setting the Mute for the PA Input
The Auxiliary Muting function reduces the volume of the audio signals that are
coming into the auxiliary input terminals every time an announcement over the PA
system is made. This is accomplished by wiring the high impedance signal (70 or 25
Volt) from the PA system to the PA input terminals.
Adjust the audio level of the PA system that is connected to the ‘hot’ and ‘common’
terminals of the PA input terminal (15) with the PA input volume (16), as shown in
the diagram.
【notes】
The AUX mute for the PA input terminal operates independently from the
teacher voice mute settings.
Every time the PA system is activated, the announcement is reproduced
by all of the speakers attached to the main unit.
