3. BUS Line Inputs / Outputs

The AMP1200 has two common or BUS inputs that

receives audio signals from standard line-level audioCLOSE UP OF CONNECTIONS 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 ampli -

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.

minutes to return from ready to standby mode.

5.Trigger Input / Output

The trigger input is a handy feature when connecting the

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 AMP1200 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 AMP1200 can also provide		9. Speaker Output Terminals
