. PRIORITY ADJUSTMENT VOLUME (PRIORITY MUTE)
It adjusts how much the volume of the INPUT 3~6, EXT IN, and PAM module decreases if your device is
operated under the following conditions.
If you minimize the volume, the volume size to decrease is set to maximum; if you maximize the volume, the
volume size to decrease is set to minimum.
1) If a signal is input into INPUT 1 and 2, the RM-05A or the CHIME is operated
2) If an external MUTE switch terminal is operated
3) If a signal is input into the TEL IN terminal
※ INPUT 1 and 2, RM-05A, and CHIME signals are output prior to the INPUT 3~6, EXT IN, and PAM
module signal.
10. PRIORITY SELECTION SWITCH
It is a switch to turn on/off the priority operation of INPUT 1 and INPUT 2. The corresponding channel will
perform the priority operation only when the switch is turned on. The priority is as follows
EM > TEL IN > INPUT 1/RM-05A, INPUT 2, CHIME > INPUT 3/4/5/6, EXT IN, PAM Module
11. EXTERNAL MUTE SWITCH TERMINAL
It is a terminal to connect with the switch to mute the sound of the INPUT 1~6, RM-05A, CHIME, and EXT
IN, module externally in the device. When contact closure is input into the external MUTE switch terminal,
the sound volumes of the INPUT 1~6, RM-05A, CHIME, EXT IN, and PAM module are turned down
according to the values adjusted by the TEL IN Priority Adjustment Volume and the INPUT 1 and 2 Priority
Adjustment Volume.
12. EXTERNAL CHIME (EXT CHIME) SWITCH TERMINAL
It is a terminal to connect with the switch to operate the 4-note scale chime in the device externally. When
contact closure is input into the external chime (EXT CHIME) switch terminal, the 4-note scale chime is
operated.
For the EXT CHIME switch, use a momentary switch by which the On/Off status is not fixed.
13. EXTERNAL EM (EXT EM) SWITCH TERMINAL
It is a terminal to connect with the contact closure for emergency broadcasting. When the corresponding
contact closure is input, the internally saved emergency broadcasting message is output. At this time, you
cannot adjust the output volume produced by the Main Volume Control.
Even if the Power Switch in front is turned off, the device is automatically turned on when the EM contact
closure is input. And then, the emergency message is output through the entire speaker zones without
considering the status of speaker selection switches in front. In this case, the device will be automatically
turned off and will return to the original mode when the EM contact closure is off.
14. MIX OUTPUT (MIX OUT) TERMINAL
It is an output terminal to record the sound output from the device or to connect with other amplifier(s) used
in parallel. You cannot adjust the signal output volume with the Main Volume Control. A balanced audio
signal is output (signal +, signal-, GND).
