a
AC power connector — Connect a standard IEC AC power cord here for power
input (100 VAC to 240 VAC, 50/60 Hz) to the internal, autoswitching power supply.
b
Power switch — This rocker switch turns power to the amplifier on or off. The off
position also disables remote standby (see d).
c
Power indicator LED — This LED lights:
• Green when the amplifier is receiving full power.
• Amber when the amplifier is in standby mode. Standby mode turns off all
outputs from the amplifier, although the amplifier is still receiving power.
d
Remote standby connector — Connecting pin 2 to ground (pin 1) places the
amplifier in standby mode. Standby mode turns off all outputs, although the amplifier
is still receiving power.
NOTE: The amplifier automatically enters standby mode after 25 minutes of
inactivity (+/- 5 minutes).
Use the included 2-pin, 3.5 mm captive screw connector to jumper the pins.

e
Limiter/Protect indicator LEDs (channels 1, 2, 3, and 4) — These LEDs
(representing output channels 1, 2, 3, and 4) light red under four circumstances:
• When audio clipping occurs, the LED of the corresponding channel blinks once
per clip occurrence.
• When the amplifier overheats, both LEDs are lit. The LEDs are not lit after the
amplifier cools down and recovers from the overheated condition.
• When DC output is detected, the amplifier is malfunctioning and the LED for
the corresponding channel is lit. When a malfunction occurs, power down the
amplifier and power it back up. If the LED still remains lit, the amplifier requires
servicing.
• When the output leads are shorted, the LED of the corresponding channel is lit
until the short is removed.
f
Signal indicator LEDs (channels 1, 2, 3 and 4) — These LEDs (representing input
channels 1, 2, 3 and 4) light green only when an input signal is detected on the
corresponding channel.
