I have two issues which might be related. When switching to MIC+PHANTOM for a phantom powered mic, the whole thing just turns off. Turning it back on reveals no change has been made. Second issue is that when plugging in a wireless mic, I get nothing picking up on the TASCAM, even though I see levels bouncing on the wireless set itself. It works fine for XLR plugged-in dynamic mikes and also the internal mikes. I've checked the cabling, seems fine, also the settings I've triple and quadruple checked. Any ideas?
