Ok so I'm having trouble figuring out what I need to make this work (I'm assuming it should?). At my church we have a Yamaha O1v soundboard, which has an SPDIF out on it. I'm trying to figure out the best way to record our services, and I'm assuming that would be the best way. Problem is, I have no idea what I need to make that go into my MacBook Pro. Is it possible to run it straight into the audio-in with some sort of converter or do I need a USB/Firewire interface of some kind? Also, if I use that, will the separate channels from the board appears as separate channels on the computer in Garageband by any chance, or will it still just be a single channel still? I guess that depends on the board doesn't it? Thanks!
