0V - 5V output:
Switching on/off the music with a 0Volts or 5Volts switching output.
5V
+
Connect the positive contact of the 0Volts / 5Volts output to the connection ”POS” and the other
contact to the connection “NEG”. When the 0V/5V output sends out 0V, the music will play
normally, when there is 5V at this output, the music is muted. The alarm/music mute indicator
LED (28) at the frontpanel will light up to indicate the music is muted remote controlled.
18) When the music is muted through the alarm/music mute input (N), an alarm message, alarm
signal or evacuation message can be played via the priority input (O). Simply connect the alarm
message-, alarm signal- or evacuation message player to the priority input RCA connector. For
a correct operation, the level must be set in advance. This can be done as follows: turn all other
music sources off, put the VU-2 signal select switch (27) on position SUM, start the alarm-
message, alarm-signal or evacuation-message, turn up the level with the priority signal input
level potentiometer (P) until the green 0dB LED’s on the VU-meter (13) lights up sometimes. At
that moment the level is set correctly. Later when an alarm has to be given, the alarm system
can mute the music through the alarm/music mute input and the message player can be started
to play the message.
SUBSONIC FILTER
The two master outputs and the monitor output have a subsonic filter to protect the bass loudspeakers
from DC and subsonic signals. This filter cannot be switched off. The filter gives a reduction of 25dB at
10Hz.
