APower indicator LED — This LED lights:

zz Green when the amplifier is receiving full power.

zzAmber when the amplifier is in Standby mode. Standby mode turns off all outputs from the amplifier, although the amplifier is still receiving power (see D of “Rear Panel Features and Operation).”

BOver Temp indicator LED — This LED lights red when the amplifier exceeds the recommended operating temperature for optimal lifetime. The LED turns 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.

CSignal 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.

NOTE: These LEDs are also located on the rear panel.

DLimiter/Protect indicator LEDs (channels 1, 2, 3, and 4) — These LEDs (representing output channels 1, 2, 3, and 4) light red under the following circumstances:

•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.

•When the output leads are shorted, the LED of the corresponding channel is lit until the short is removed.

NOTE: These LEDs are also located on the rear panel.
