Bought an abandoned storage unit today. This was in there. It fires up, and all channels receive power input. Will connect a mic to each of the 24 preamps tomorrow (if stupid family stuff doesn't get in the way ). Not sure what I'm going to do with it, even if it works. I'd have to rig up some kind of interface to get the Tascam channels into my DAW. I could send 8 channels into my Audient ASP380 via patch bay, bypassing the Audient's preamps and into a laptop via Audient iD22 interface. However, since Audient preamps are the cats meow, why do that? Possibly send 8 groups out of the Tascam if I need more inputs for drums/keys. Guess I could use it as a summing mixer, as well. Maybe sell it?
