I just want to get this clarified how this is done. I am rather dense, so bear with me. If I were to get a Mackie Mdr, Hdr, or Sdr and a mixer, like a mackie 32-8, How would I go about hooking it up? I have stereo mains right, would I have to physically patch the stereo out of the mixer to the two channels that I want to record to. How would I record eight, 16, 24 tracks at once?
