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. This
connector may be replaced by the Flexible Conduit Adapter Kit (part number 70-228-02)
as described in “Flexible Conduit Adapter Kit Installation” on page 19.

LIMITER/
PROTECT
When the output wiring is shorted together
When audio clipping occurs, the corresponding channel’s LED 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.
