Controls

Input attenuators

The four inputs attenuator controls, located on the front panel adjust gain for their respective amplifier
channels in all modes. With the attenuator fully clockwise at 32dB on the silk screen (minimum
attenuation), the amplifier gain will be set to 32dB ( 40X ). The silk screen scale is calibrated on 2dB
increasing attenuation, and a step by step detent on potentiometer helps for calibration ,except for the
last three positions (-∞, 4, 14 dB).

Led indicators and controls

Led indicators
Your DIGAM amplifier has LED indicators on the front panel. "READY" and "TEMP" leds are common
to both channels on each device and the other "SIGNAL" and "PROTECT" leds are present for each
channel. Each channel has an 5-segment LED bar for the output signal. Each segment will be
lightened every 3dB. The green segments will be lightened during normal working. The yellow LEDs
of the bar will be lightened at -3 dB. If the level of the audio signal exceeds the channels output
capability, it clips, triggering the red LED.

Front panel controls

The power switch, gain controls and LED indicators are on the front panel.
1) Power switch
2) Gain
3) Protection LED (PROTECT) (one for each channel)
4) Signal Present LED (SIGNAL) (one for each channel)
5) Over temperature LED (TEMP): one for each power section
6) Amplifier ready LED (READY): one for each power section (the led will be on if the amplifier works correctly )
