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
f of
Rear Panel Features and Operation on page 13).
b Over 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 ambient temperature is within the specified range.
