Our video production studio consists of a large cyc half green and half white. We currently put a wireless lavaliere on our talent, but would like to move to a technique that better hides the microphone. One attempt was using vampire clips for the lav, but they kept breaking. The other was to use a shotgun mic on a boom. The ceiling is the sound absorbing acoustic tile (that could be better)and the floor is painted concrete. We hung three large blackout curtains roughly 12'x 18' to box in the talent. The shotgun almost works, but we can't reduce the echo to acceptable levels. Our thoughts are the mic is not designed for it? Its a Sennheiser, but I can't locate the model. Perhaps a big windscreen? We don't have a huge budget, so any suggestion would be really helpful.
Did they achieve the desired results before you broke them?
Smaller lavs are more easily hidden. Try the Countryman B6.
Shotgun mics are not the mic of choice for interiors unless the interior is a well-damped sound stage. A hyper or supercardioid is a better choice but you need that on a boom and not more than about 16" from the talent's mouth, otherwise you hear the room.
