walters, is that you?

I think you're getting channels and tracks thrown into the same terminology, which some machines have a combination like the TASCAM 2488 or 388, but what your assignment sounds like you are looking for info on is a 24 channel mixing console and a 24 track recorder. Soundcraft will give you information on 24 channel boards they manufacture, but I don't think they manufacture multi-track recorders. For multi-track recorders look at something like OTARI or Studer on ebay for tape machines, or Alesis or Mackie for stand-alone 24 track digital machines. And then there is the whole PC/MAC/software option. Anyway, this should at least start you in the right direction. I use a Mackie 24.8 bus 24 channel board with an Alesis HD24 24 track stand-alone recorder, so if you have any specific questions, I'll try to answer them.
