TRIGGER CONNECTIONS
This amplifier features several trigger inputs and outputs. The trigger inputs activate when
a +3 ~ +30 VDC@1mA voltage is applied, while the trigger outputs deliver ether +11.5
VDC@1mA ~ +10 VDC@5mA or +12 VDC. Each trigger output is used for activating another
trigger-enabled devices, such as a motorized projection screen.
Line/Bus Trigger In
Each zone has a Line/Bus Trigger In, which is a 3.5mm TS plug.
Normally, the zone outputs the audio signal on the zone's LINE IN
(10) RCA audio inputs, but outputs BUS AUDIO when a +3 ~ +30
VDC@1mA voltage is applied.
Master Control In
The amplifier has a single Master Control In (13), which is used to
turn the amplifier on or off. To use the Master Control In (13)
trigger input, place the POWER switch (16) in the OFF position,
then whenever a +3 ~ +30 VDC@1mA voltage is applied, the
amplifier will power on. When the voltage is removed, the
amplifier will power off.
