We bought this mike for church use a few years ago, but since then it has remained stored up due to a very annoying reason: it picks up and transmits sound signals from a neighboring church, loud and clear.
Please anyone with a knowledge of what we can do to fix it?
We tried removing the antennae at the back, that didn't work.
There are no further controls other than the ones shown in the pic.
We use 16 channel mixer and power 1800 wharfedale power amp for it.
Sunday is not far, we have a mega service coming up and we need all the mics.
The signals it picks are way stroner than the one it receives from its mic.
