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amplierisreceivingfullpower.
• Amberwhentheamplier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:

per clip occurrence.
• Whentheamplier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amplierismalfunctioningandtheLED for

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.
