Can someone help me. I have a wireless mic from Sennheiser where i can put the Output Level down in the Receiver to -24db. But also have cable mic also from Sennheiser where i cant put the Output down in the mic so. My Problem is that i allways have the master at 1/2 then i have Problems at the second Point at miclevel. It´s not praticable to put the masterpout down always when i use the mic and when i Need Music i have to put the mic down and the master higher. Can i somewhere reduce the mic Level???
