FRONT PANEL:
1. Master Power Switch / Indicator LED
Front panel pushbutton power switch turns the amplifier on and off. When the switch is on and the indicator LED is red,
the amplifier is in standby mode. The remote turn on switch (located on the rear) is either in the “trigger” or “auto”
position. When the LED is blue, the amplifier is fully active. The master power switch will turn off the amplifier no
matter which power mode has been selected.
2. Zone Status Indicators
Each pair of channels or zones has a bi-color LED to indicate its operational status. These indicators provide quick and
easy troubleshooting of the system. If the circuitry determines that a channel must be shut down due to excessive heat
or low impedance (a short), only the channels that are affected will be turned off causing the zone LED to turn red. The
remaining zones will continue to operate and maintain a blue LED status. Once the condition has been corrected for the
zone in question, the status LED will return to blue.
Note:
When the power LED is red and the zone status LEDS are not lit (off) indicates the unit is in stand by mode.
REAR PANEL:
3. BUS Line Inputs / Outputs
The Amplifier has two common or BUS inputs that receives audio signals from standard line-level audio sources and
sends them to any or all channels. The BUS line outputs are direct feed-through to allow the BUS inputs to be fed to
other amplifiers. Be sure to use high quality RCA cables that feature low impedance, shielding and high quality
connectors.
4. Remote Turn-On Switch
This switch selects the turn-on stimuli that will put the amplifier in ready mode. “Trigger” setting relies on 3-30V AC/DC
voltage going into the trigger input to activate the amplifier. “Auto” setting senses a signal on the RCA line-level inputs
and automatically puts the amp in ready mode. “On” setting puts the amp constantly in ready mode so that it can be
controlled by the master power switch on the front panel. In “Auto” mode, the amplifier will take approximately 15
minutes to return from ready to standby mode.
5. Trigger Input / Output
The trigger input is a handy feature when connecting the amplifier to an automated audio system. The 3.5mm mini-plug
jack will accept a 3-30V AC/DC output from another device, or from a separate power supply. When the trigger input is
energized, the amp turns from standby to ON mode. When using the Amplifier with a receiver without a trigger output,
the voltage can come from a 12V wall wart (3.5mm tip-positive connector) plugged into the receiver’s switched outlet
and the trigger input. The Amplifier can also provide an output trigger voltage (12DC @500mA max.) to turn on and off
other devices in the audio system. When the amplifier turns off (standby mode), the voltage will drop to zero.
