Phantom power's a problem wit the dynamic mics I am using, and I don't think I have a chooice of phantom or not per channel. External power is npot a bad idea, if possible, since we sue a number of devices on stage (tuners, pre-amps, etc). For now I carry lottsa extra batteries!

Since I am not running the signal back to poweramps, but rather using the DI to run a an acoustic instrument pick-up signal to the board, it sounds like I have the option of not worrying about a "ground lift" - I do have 4 lines on the snake for 1/4" input/output, if I choose to send a line level to power amps for, say monitors.

Who's DOD?
