So I have mics set up on my drum kit. There are 7 all plugged into the xlr plugs on the mixer. I have a 1/4" to 1/8" cable connecting the mic in on the camcorder to the mixer. What do I plug it into on the mixer. The only time I got good audio was in 'Aux Send', but it was extremely quiet and when played on the computer, played stereo rather than 7.1 surround. Any help is appreciated.
