Would an analog mixer/any sort of mixer be the best way to go about this? I own a Denon MC-6000 and my brother has the S4. Or would this be totally unnecessary? Also, if it is the best possible way, any recommendations? Thank you again for you time
I just did this today with my crown XTi amps and if you use CH1 + CH2 mode you can run 1 XLR from the first controller and 1 XLR from the second controller directly into the amp on the left and right channels. No special equipment necessary.
