Notes

• The MC2 is the amplifier in the main sound rack, and is located above the sound patch panel
• The Yamaha amp is located by the entrance of the techbox
• The sound desk power switch is located on top of the Yamaha amp
• If you don’t know what you’re doing please ask someone who does
• The Yamaha is dead and there is a new amp above the MC2 in the rack
• This is best practice only to avoid a "pop" through the amps and desk. It doesn't damage the equipment if you don't follow this procedure!
