How to setup and use the cafeteria public address system
The sound system's components are in the closet on the far wall of the cafeteria. This is what it's components look like.
- Turn on the Mackie sound mixer board.
At the rear of the Mackie sound mixing board is the on/off switch (red arrow in the image below).
Turn that on. When you do, several lights on the front panel of the mixer board will turn on.

There are four microphones, numbered 34, 35, 36, and 37.
The microphones are stored on top of the small shelf unit along the wall.
Note the white projector remote and spare batteries to the right of the microphones. The projector mounted in the cafeteria ceiling isn't functional at this time.

The two antennas are dipoles, and they function best when in a vertical position. Do not change their position.
The antenna on the left connects to microphones 34 and 35. The antenna on the right connects to microphones 36 and 37.
Fun fact: the antennas on a Wi-Fi router are also dipoles, so, pointing them straight up will improve the range of your Wi-Fi signal.
9. Test the microphones.
