SETTING UP ROUTINES
- Connect a power-amp, recorder or transmitter to the left/right outputs.
- Connect a high impedance headphone to the "phones"-jacks on the front.
- Connect the microphones as described.
- Act like wise with turntables, tapedecks and jingle machines.
- Now that everything is connected, follow the adjustment procedure.
(Note; for mics , only activate the red mic switch, for line level on input all switches in
the up position)
- Put on your headphones and turn the headphone-volumecontrol to "12 o'clock" position.
- Turn all the gain-controls and the master-control to the left.
- Set all equalizer-controls to the "12 o'clock"position.
- All pushbutton-switches should be in the up position. (See above).
- Switch on the power-supply, the first led in the led bar should be on.
SETTING UP AN INPUT CHANNEL
- Depress the CUE switch in a channel that is connected to a source.
- Now slowly turn the GAIN control clockwise until you hear and see the input signal on the
ledbars in the master section.
- You can change the input sound by adjusting the equalizer-section.
If you have adjusted the equalisation, once again check the level on the ledbar, because
increasing specific parts of the frequency spectrum can easily ad more gain to the signal.
- The ledbar indication has to be between 0 dB and +6 dB (the yellow area) to get a proper
level on amplifiers or tape machines.
- The ledbar is a VU meter indicating the absoluut level that enters the console.
It is calibrated to indicate 0 dB on the scale corresponding with a +4dBu output level.
- Release the CUE switch so the ledbar now reads the output signal again.
- Now push the ON button to connect the input signal to the fader.
- Now fade to the "8" position screened alongside the channel faders and fully turn up the
master fader. Further volume adjustments have to be realized on the power-amp.
- The other inputs are likewise ad justed, using the "CUE" switches to pre fader listen the
connected sources and usage of the the input gain for precise adjustments.
Be carefully not to place the Discom 4 near heavy power transformers, as used in power amps
etc, this may couse hum, inspite of the thick metal case.
