1. Plug a microphone or a mono signal source into one of the mono channels.
2. Or a stereo signal source into one of the stereo channels.
3. Connect MAIN OUTPUTS to an amplifier (Jack Balanced).
4. Turn power switch on. The blue led (POWER) lights up.
Mixing:
1. Set the LEVEL of each channel at "0" position
2. Turn up "MAIN MIX" to desired level, in relation to the amplifiers / speakers you are using. Preferably,
don't exceed level "0" or "+6" on the LED indicators.
3. Adjust LEVEL of each channel to obtain your own mix.
6. If necessary, adjust tones and repeat above " set levels" procedures
General indications:
1. The optimum GAIN and/or LEVEL position is near to 0 while the optimum position for the MAIN MIX is
