sweetbeats - check out what KineticSound said about it:
I asked a similar question in the "Newbies" section and got an interesting response:
"KineticSound:
What a cool find. Someone who mentioned it looked like an old broadcast board was exactly right. I remember seeing consoles like this at my father's TV station when I was a kid. Most of those were TEAC boards that had pretty good mic pre's in them - but understand that this board was probably not designed to do much other than amplify and mix voices for radio and/or television broadcast. Can't say if it would do any good as a direct box, etc.
It won't convert analog to digital, of course - digital wasn't in the broadcast vocabulary when this thing was made. But you could use the preamps in it (if you can get it working, that is) as a front-end to an A/D converter.
From what I remember of these units, they had notoriously noisy pots, so you might want to have a AV repair shop have a look at it and clean the pans, eqs, sends, faders, etc. and check the signal flow of the preamps."
