I have a bad feeling that Terry is correct. I’m using the 1/4 to 1/4 plug from receiver to mixer as well as xlr to xlr from the receiver to mixer. I’ve tried multiple cables and inputs,and checked every setting on the mixer which is working fine. The receiver is junk. There are hardly any instructions or info that came with it or even in existence online. I’m gonna look for a better pair of mics. Any suggestions?
