We are putting together a package of wireless mics and receivers for certain users of our high school stage.
I refuse to hand our "good" bodypacks to kids who are not members of our cast, so this cheaper wireless gear is for the various in-school talent and pageant events we support each year.
We started with a Nady Quad receiver and four wireless lavs.
Trouble began when we tried to add a cheap import dual handheld set-up.
My chief student sound tech reported a loud buzz on both channels.
He thought it was lessened by using one channel at a time, but I think it was just softer because he had one channel vs. two channels of buzz open.
I tested the equipment one evening and got no buzz, just a cheap mic that could be tamed by EQ to get acceptable results.
We tried it again a few days ago and the channels were unusable, steady loud buzz.
The noise remains with -all transmitters off
-gain on the receiver all the way down
-no RF signal showing on the receivers
-new cables
It seems unlikely that we are picking up intermittent RF interference, but I can't easily rule it out.
The fact that the Nady gear, as well as other gear, has worked fine from the same position and power supply makes it unlikely that the problem is a power supply/ground loop issue.
I am uncertain what to do next.
Your suggestions?
