1. To set up the sound desk, plug the main desk into power, then plug speakers into power and desk using XLR cables. Connect audio sources like a CD player to the desk using phono or audio jack cables. 2. Turn on equipment in the correct order: sound desk first, then audio source, then speakers to avoid popping noises. 3. Operate individual channels by powering them on and adjusting gain until lights are at maximum yellow, then pan each channel to the correct speaker. Use the master fader and channel faders to control overall and individual volume levels.
