16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS
INSTALLATION CONSIDERATIONS
3-24 VOLT AC/DC OPTO-ISOLATED VOLTAGE TRIGGER
- The Power
switch on the front panel must be in the “On” position for the voltage trigger to
function. When a Trigger Plug is inserted into the rear panel connector and the
sensing circuitry detects a voltage, the amplifier is turned on. Once the Trigger
voltage is turned off, the sensing circuit instantly turns the amplifier off. The
amplifier is off when there is no 3-24V AC or DC voltage detected at the trigger
input. Voltage triggers can be suplied by automated switchers, some video
projectors, some surround sound processors, or something as simple as a
12 volt AC wall adapter plugged into the switched outlet of your stereo receiver.
Linear DC wall adapters are not recommended; the long discharge time of the
DC adapter’s filter capacitor will delay the turn-off of the amplifier.
Trigger sources must be 3-24VAC or DC, 20mA or greater.
Allow a minimum of 2” of depth behind unit
to accommodate cables and connectors.
If the cabinet rear is not open to fresh air or if
you’re using low impedance loads, install two
“boxer fans” to provide continuous air flow into
and out of the cabinet.
If the cabinet rear is not open to
fresh air, install two small “boxer
fans” to provide continuos air flow
into and out of the cabinet
Make sure that there is a minimum of 5” of free air
space above the amplifier and 3” on each side for
proper ventilation.
