To set up the outputs on an analog mixer, connect the main left and right outputs of the mixer to the inputs of the amplifier using the appropriate audio cables, then connect the amplifier to the speakers. For auxiliary outputs, connect an AUX output on the mixer to the input of a monitor speaker, headphone amplifier, or effects processor. Raise the main and AUX master levels, then use the channel AUX knobs to control how much of each channel is sent to the auxiliary output without affecting the main mix. Test the system and adjust the output levels until the audio is clear and free of distortion.
NOTE for the outputs to work make sure to go to the amplifier section
