LED blinks once 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 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 amplier requires
servicing.
