There is a master volume with a power symbol next to it on the right side of the front speaker, press it in to turn the system on or off, turn the dial up or down to adjust everything.
The wireless microphones are muted by default when put on the charger, so just pick it up and press the round power button on the handheld or top white button on the lavalier it will then turn blue and just work.
Mic volume is on the arrow buttons on each mic and nowhere else.
There is a 3.5mm aux input cable that can be used for anything. It has a separate volume knob labelled "Input".
