Hello, first of all, love my RCP ii , but so here is situation
I got a pair Rode M5, a pair of Sennheiser MKE 600 , and 2 line outpits from downstairs main mixer. This is my church set up. SENNHEISER are used for the front of the house choirs, instruments and other performances. Rodes are for crowd singing and 2 lines from main mixer are for the preachers and other direct instruments that being send to me. I have only 4 XLRs inputs on my RCP2. So, my question can I combine signal from downstairs into 1 fader and so is crowd singing also into one fader?
