Hi,
Really need peoples help if possible. I am not massively technical but i will do my best to explain what is going on. I work for and AV installation company doing the admin
. But we have two issues currently. Both scenarios involve a 100v PA system with speakers (good quality kit)
First Scenario:
Two electric screens that when the remote is used to lower and raise the screens, when the screens stop a massive large audio bang can be heard from the speakers. The audio from the projector is fed back via screened audio cable to the PA, But we have done this 100 of times with no problems.
Second Scenario:
One electric screen and 1 projector (Benq) - this one is a bit weird, so when you press the button the projector remote to take it off standby, you then get three loud bangs from the speakers. The only link i can see between both scenarios is that the controller for the screen and the projector are both IR.
I would welcome anyone`s thoughts on this as we are a bit stuck currently.
Thanks All
Neil
