A 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 Fof “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.

ÑLimiter/Protect indicator LEDs (channels 1 and 2) — These

LEDs (representing output channels 1 and 2) light red under four circumstances:

1 2

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.

NThese LEDs are also located on the rear panel.

ÖLimiter/Protect indicator LED — This LED (representing the output channel) lights red under four circumstances:

• When audio clipping occurs, the LED blinks once per clip occurrence.

• When the amplifier overheats, the LED is lit. The LED is not lit after the amplifier recovers from the overheated condition.

• When DC output is detected, the amplifier is malfunctioning and the LED is lit. The amplifier requires servicing when this event occurs.
