I have a older Gemini PA-7000 preamp. I tried to use the mic jack and nothing but a pop, when the mic is plugged in, and as I start to turn the mic level up, then nothing. I am trying a Behringer xm8500 dynamic mic, a xlrf to 1/4" trs cable. Then I added a 1/4" trs to ts adaptor and the same thing. I have attached the schematic. I don't know if this is the correct mic setup or if the preamp mic circuit is bad. Everything else on the preamp works fine.
Thanks
