I have a 14-channel mixer. During a live performance I want to play some channels to loudspeakers while simultaneously recording, but I want the recording to contain more channels that are not played through the loudspeakers. Details and diagrams within.
I'm now doing sound for our UU fellowship and we have a Mackie 1402 mixer. I've made some annotated diagrams of how it's currently hooked up, here:
Back Panel (No connections currently used here.)
How it works now:
Mic inputs 1 - 5 are unmuted when someone's using them, otherwise they're muted. The room speakers are plugged into MAIN OUTPUT and the CD Recorder is plugged into the TAPE OUTPUT, so everything people hear over the speakers is recorded on the CD.
How I'd like it to work:
I'd like to be able to add a mic on the piano, add this input to the recording, but not play it back over the loudspeakers.
In short, how can I decide that some inputs should be recorded and some should be played out loud even if these groups overlap? If I need to re-arrange wires that's totally fine, I just can't figure out how to accomplish it.
If I need to use the ALT 3-4 bus and give up the Mute feature, that's probably fine, as long as turning down a channel's fader accomplishes the same thing.
