Thank you Rod,
I appreciate your time in replying. I have read that in other places too.
Generally I'm only running 2-4 mics at a time, and since their routing changes between instruments, and songs, I'm not looking for a way to route mics. I'm much more looking to run line level interconnects and (usually low voltage d.c.) power lines. The kind off thing you generally only change when re-locating equipment, or fundamentally altering the type of music worked with (e.g. acoustic jazz to electronica, etc...).
My studio is a one room affair, and I generally have only 1 or 2 musicians tracking at a time. So mic runs are not really an issue for me at this time.
Obviously, if I ever expand to an external tracking room, I'll need to re-evaluate my needs.
