DO NOT LOSE THE KEY
Without it, you can't open anything. Put it back in its hiding spot right after every use.
Volume at a glance
Knobs on the back of the speaker with the cables plugged in. Turn right for louder, left for quieter. They control both speakers, as long as the Mix Out cable is connected to the other speaker.
Setup
- Power the speakers
Plug the extension cord into the speaker on the cart, then plug in the second speaker that rides on top of the cart.
The speaker cart. - Open the cabinet
Lift the top section to find the white key. Hold it against the cabinet over each door's lock and move it around until you hear a small click, then open the doors.
Where the key lives. 
Hold it over each lock until it clicks. Put the key back right away. Lose it and you can't open anything.
- Grab what you need
- Speaker link cable (strapped up)
- Video + audio cable (lying inside)
- Microphone in its bag (already on its XLR cable), only if needed
Inside the cabinet. This is how it should look when you put it back. - Link the two speakers
Unstrap the link cable. Each end is labeled.
- End marked CHANNEL 1 goes into Channel 1 on the back of one speaker.
- Run the cable over and plug the end marked MIX OUT into Mix Out on the other speaker.
Each plug only fits one way. Don't force it. The speaker photo at the top shows where Channel 1 and Mix Out are.
- Connect video
Unhook the cable from inside the cabinet and plug it into the port on the side of the stage. The HDMI end goes into your computer.
Playing a DVD instead? The DVD player and its remote are in the cabinet below. Leave them in there.
Video port on the side of the stage. - Turn on the projector
Point the projector remote and press and hold Power until you hear it kick on and see it light up. The remote tends to work better from one side of the room, so move if it doesn't respond.
Aim the remote at the projector on the pillar. - Lower the screen
Go up to the tech booth and press and hold the screen switch. Check that nothing is underneath before it comes down.
Screen switch by the tech booth. - Connect audio
Find the cable tagged HEADPHONE and plug it into your computer's headphone port.
Look for the orange Headphone tag. - Turn on both speakers
Flip the power switch near the bottom of the back panel on each one. They're identical. See the speaker photo at the top.
- Set the volume
Use Channel 1 for the computer. It controls both speakers when the Mix Out cable is connected to the other speaker. You shouldn't need to touch the other speaker, but if it's too quiet, turn up its own knob.
Using the mic? It's already attached to its XLR cable. Pull it out of its bag, plug the cable's end into Channel 2, and use the Channel 2 knob for mic volume.
If something's off
Computer is plugged in but nothing shows on the screen
The projector is probably on the wrong input. It has HDMI 1 and HDMI 2. Switch to the other one with the remote.
One speaker is quieter than the other
Make sure the Mix Out cable is plugged into the other speaker. Without it, the knobs only control one speaker. If it's connected and still quiet, turn up the knob on the quieter speaker.
