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.
See
f of “Rear Panel Features” in this chapter.
b
Over Temp indicator LED — This LED lights red when the
amplifier exceeds the recommended ambient temperature for
optimal lifetime. The LED will turn off after the amplifier has
cooled down sufficiently.
Should the LED light, check the following:
• Verify that the placement of the amplifier allows for adequate
ventilation and airflow.
• Avoid placing other equipment on top of the amplifier.
• Verify that the operating temperature is within the specified
range.
Ñ
Limiter/Protect indicator LEDs (channels 1 and 2) — These
LEDs (representing output channels 1 and 2) light red under
four circumstances:

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 recovers from the overheated
condition.
• When DC output is detected, the amplifier is malfunctioning
and the LED for the corresponding channel is lit. The
amplifier requires servicing when this event occurs.
N These LEDs are also located on the rear panel.

Signal indicator LEDs (channels 1 and 2) — These LEDs
(representing input channels 1 and 2) light green only when an
input signal is detected on the corresponding channel.
