Turn on the sound system (follow these steps)
Ensure that the master volume on the board is up and on (second to last fader and check that there is a green "on" above it)
Change to fader set B (located near the bottom right side of the board)
You should see one set of faders that are colored white (they are the stereo music and they move together)
For now, mute these channels by making sure the "On" button is not green.
If you plan to use bluetooth:
Find the bluetooth device and ensure it is plugged into the two channels that were just discussed
Make sure it is on (there should be a red and green light). You may need to unplug the cord from the computer and use that as it does not take a regular USB-C cord. It needs to be higher quality like the computer cord.
Find the device on bluetooth and enter in the code if it's your first use
If you plan to use Aux, find the aux cable and plug in both ends to the channels just mentioned, and plug the other end into your device.
Play music, make sure the volume of your device is up, and see if you can see a signal near the top of those two channels (green bars rising and falling).
Turn the faders all the way down, turn the channel to "on", and slowly turn the faders up until they are at a preferred level.
