To use this Aviom A320 personal mixer, first connect your audio sources to the appropriate channels. You can then adjust the volume and other settings using the remaining knobs. Since the knob cover is missing, be careful not to damage the knob when making adjustments. For maintenance, keep the mixer in a dry and clean place. Regularly check the connections to ensure they are secure. If you notice any other issues, it's best to consult a professional.
