Large equipment can be find either on the stage wings or in the basement in the caged section.
Cords can be found in the cabinet under the stage box
All mikes and instruments on the stage shoud be plugged into the stage box
The stage box has 2 rows of inputs, each with inputs from left to right of 1 through 16. The top row represents 1-16 on the board, the bottom row represents 17-32 (you will need to do math, sorry).
All instruments that are going direct will need a DI box or an adapter from 1/4"-F to XLR-M (found in the cabinet).
There are 8-channel snakes. The one with blue ends is usually put near the drummer and the other is usually put on the opposite side of the stage from the stage box. Channel 4 of the blue one doesn't work. Be sure to pay attention to which number of the end of the snake gets plugged into which channel. Try not to mix up the snakes.
