Power Selection: Switch to control the power-on behavior of the amplifier. When in
the On position, the amplifier is always on whenever the Power Switch (1) is in the
On position. When set to Auto, the amplifier will automatically go into standby
mode when no audio signal is detected and will power on when an audio signal is
detected. When set to the Trigger position, the amplifier will power on or off
whenever a 12-volt trigger is applied to the Trigger In (8). When set to the Auto or
Trigger positions, the Power Switch (1) on the front panel should be left in the On
position.

Trigger: 3.5mm jacks for 12-volt Trigger In and Out. The Trigger In can turn the
amplifier on or off and the Trigger Out can be used to control other devices.
9.
Speaker: Removable Phoenix connector for attaching the speaker wires. When
connecting a single speaker in bridged mode, the negative lead should be attached
to L- and the positive lead to R+. It can accept speaker wire up to 12 AWG.
10.
AC IN: IEC 60320 C14 panel connector for attaching the included power cord.
THERMAL PROTECTION
The amplifier monitors its temperature and will activate the thermal protection circuit if
the temperature exceeds a safe limit. This can occur if the amp has been operated at high
volumes for an extended period of time, if it has inadequate ventilation, or if the speaker
load is below the minimum impedance of 4 ohms. The amp will shut down when the
Thermal Protection circuit engages. You must turn off the amp's power switch and wait
until the amp cools down, then power the amp back on.
SHORT CIRCUIT PROTECTION
If the amplifier detects a short circuit on one or both speaker outputs, the Power LED (2)
will glow orange and output will be disabled. If this occurs, turn off the amplifier and check
the speakers and speaker wires for a short circuit.
