10
in the OUT position and is set for Bridged operation when the switch is in the IN
position.
12.
VOLTAGE SELECT: Slide switch for setting the input AC voltage level to nominal
120V or 240V operation. The switch is set to the 120V position at the factory and the
appropriate fuse is installed. If you change to 240V operation, the fuse must also be
changed to the appropriate type.
13.
MASTER CONTROL IN: 3.5mm jack for connecting a +3 ~ +30 VDC@1mA control
voltage to turn the amplifier ON. When voltage is applied, the amplifier powers ON
and when no voltage is present, the amplifier powers OFF. Note that the POWER
ON/OFF switch (16) must be set to the OFF position when using this feature.
14.
POWER IN: Three-conductor IEC 60320 C14 panel connector for connecting the
included AC power cord or an alternate power cord (not included) if operating the
amplifier in a country that doesn't use NEMA power plugs.
15.
MASTER CONTROL OUT: 3.5mm jack for connecting a trigger voltage controlled
device that is intended to be automatically turned on or off depending on the
amplifier's status. Whenever any zone is ON, the MASTER CONTROL OUT jack will
11.5 VDC@1mA ~ +10 VDC@5mA. When all zones are OFF, the output is 0
VDC.
16.
POWER ON/OFF: Rocker switch to turn the amplifier on or off. Note that when the
switch is set to the OFF position, the MASTER CONTROL IN (14) trigger can be used
to turn the amplifier on or off.
17.
FUSE: Fuse holder for the system fuse. If the VOLTAGE SELECT (12) is changed, the
fuse must also be changed. The proper fuse for nominal 120 VAC operating is T10AL,
250V, while the proper fuse for nominal 240 VAC operation is T5AL, 250V.
18.
REMOTE BYPASS: A six position DIP switch that determines whether the zone can
respond to IR remote control and RS-232 control inputs or not. When set to the OFF
position, the zone can respond to IR and RS-232 control signals. When set to the ON
position, the zone will not respond to IR and RS-232 control signals.
19.
RS232: Female DB9 jack for connecting an automation system or other controller for
bi-directional communications with and control of the amplifier.
