Mics>peavy 24 channel mixer, XLR outputs to MBox, Mbox to computer and stereo. I've got a lot of noise on the recordings, you especially notice it during quiet passages. If we have all the mics going (only 7 now) and stop playing the recording goes silent. Start playing and the sound comes on as well as the noise. It's like there's noise gate in there that I don't know about. But worse is the noise. It is not one particular mic, it's the over all mix. I don't even know where to begin other than to start trouble shooting mic cables. The level at each stage (mixing board, mbox, computer) looks ok and doesn't sound clipped out. Should I bring up the overall level to increase the S/N ratio and just turn down the signalgoinginto the Mbox? HELP!
