Turn On the Sound Mixer, which is in the ‘Control Booth’ located across the hallway from the Principal's Office. The On Button is located on the back side on the right, near the plug. Mixer must be set to Layer B by pushing the button in the bottom left of the board labeled as such.
Turn on the Big Red Switch located in the Sound Panel backstage left, meaning on the actual stage. (Left being if you are On Stage facing the audience.)
There is a drawer in this same panel that has microphones and cables if there is not one already set up. You want to plug it in one of the ports in the front of the stage. Any of the ones labeled WallP 1, “”2, “”3, or “”4, are fine.
BEFORE YOU START YOUR PRESENTATION - Make sure that the microphone and projector are at the volume you want. You adjust them using the respective Fader on the Sound Mixer. Only touch the gray fader. Everything else is preset.
If you are using the Projector, connect to Apple TV using your iPad or Macbook using the Screen Mirror Function. This will be in the shortcuts of your iPad, on the same section as WiFi or Brightness, or in the top right corner of your Macbook using the icon that looks like two switches next to the date and time. When you activate Screen Mirror on your iPad or Macbook, the Projector will turn on and the screen will roll down on its own.
Sound for the projector should be controlled on the device you are casting from (iPad or Macbook). It will be easier that way. If you do need to make a bigger adjustment than what the device will allow, you can use the labeled fader on the Sound Mixer.
