VU Meter:
The VU-meter is composed of three LEDs that represent three different level thresholds: -40dB, -
20dB and 0dB. When the input signal reaches those thresholds, the corresponding LED will
blink.
Temp.:
If the internal temperature of device reaches 95 degrees C, the TEMP LED will light up and the
pre-amp will stop working until the temperature falls down under 95 degrees C. The pre-amp will
come back to a working state automatically. To avoid temperature failure, please insert an
external fan to the rack system.
Overload:
The overload LED will blink as soon as the output power exceeds the nominal value. If the
Overload LED is blinking, check that the output load is well connected and still in good condition
as well as checking the level of the input signal.
Power:
The Power LED indicates the ON/OFF status.
Power fault:
This LED indicates the main/backup power supply, the LED lights up when one of them is lost
and the system will switch to the working one as well.
There is a button on the rear panel for disabling/enabling this LED indicator. It's required to
enable this LED for the PA/VA system.
