I recently started working at a cafe that uses 2 flying QSC K12s and Mackie 1501 sub. The sound was fine for a while but last month I started to struggle with voice problems. It seems I was straining too much and my cords would dry up really fast. I found something that might be the cause of the problem but need to ask you Pros if I'm on the right track. I tried to figure out why I was getting more feedback when before there was none. What was happening was that I heard myself differently and thought it was just a matter of raising the volume but when I did, it would feedback. So, I left the volume low and kept straining to hear myself. I always position myself as close to halfway between the speakers as possible and behind them so I'm only getting reflected sound. We have an old Turbosound Milan that we use as a floor wedge but it sounds so terrible that I just use it to play some music for pitch reference. I often stroll out to the audience and noticed that the sound was different out in the room as well. I looked at the positioning of the K12s and the first thing I noticed was, that the management had placed a video screen about 6" in front of the speaker right where the highs come from. the screen is one of those that has a remote control and unravels for showing videos. It's about 6" tall and about 7 feet wide. Just enough to cover both speakers at the same point ( Highs ). Could this be my problem or at least part of it? Well, that's all I can think of. Please help, Really struggling here!
It's not uncommon at all for management, decorators, event planners etc to innocently put banners, signs, blankets, displays any many other things in front of the speakers at events.
You have to educate them.
Explain that the clarity and detail of sound travels in a strait line from the tweeter and mids and if they put something in front of the speaker it will mess up your sound, period.
Explain it politely with their best interest in mind (good sound in the room) but without room for them to debate it.
This is physics, it isn't a debatable topic.
