I've got some questions for you in
return:
What are the make(s) and model(s) of the wireless systems?
How far from the
stage are the receivers?
What kind of antenna distribution (if any) are you using?
How far apart are the antennas?
What frequencies are the mics on? And where are you located?
Can you post pictures of the rig?
Without knowing anything about your rig, there are a few things I can suggest. First, check to see that the
gain is set properly on the bodypacks - it may be too low or too high. When the actor is singling full blast you should hit 0 dB on the receiver.
Also, check to see that your antennas have a 90 degree angle between them - they should NOT be straight up. The best orientation is pointing outwards at 45 degrees with respect ot the vertical.
Finally, try setting the
squelch to its minimum setting.
Squelch is like a
gate on a
microphone - when the RF drops below a certain
level, it cuts it entirely so you don't hear random static. It's possible it's set too high and is causing it to
drop out.
