Mostly we use Song-Pro to display the worship song words for the congrgation.
Occasionally we need to be able to project the PM screens on to the main Projector as well as our music screens.
Song-Pro is driven from one laptop and we have a switch-box for selecting input to the projector from either this laptop or any other (4 inputs).
How best to connect the music laptop with PM to this switch box?
The switch-box is at the back of the sanctuary at the sound/vision control desk about 50 feet plus away from the band, at the front of the sanctuary.
Is there some sort of wirless device we can use??
