Moved into temporay building which has an XLR wall jack. The exisitng wired micrphone works fine.

We plugged in a NEW Azden wireless. XLR output from Azden to XLR existing wall jack. With the transmitter in the off mode we pick up a radio station (very loud?

With transmitter in standby mode we dont hear it?

When transmitter is turned on the voice is okay but we hear low frequency hum thru speakers?

When the XLR podium microphone (wired) is used all is okay.

NOTE: the folks we're renting the room from dont want us to use their podium mic.
