Input impedance: 22k ohm
4.3.1.2 Front Panel
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 device internal temperature exceeds 95 degrees C, the TEMP LED will light and the pre-amp
will stop working until the temperature falls below 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.
Note: There is a button on the rear panel for disabling/enabling this LED indicator. It's required to
enable this LED for the PAVA system.
