Anyone using one of these? I just picked on up on the 'bay, and it came with a few XLR cables thrown in and free shipping. I'm pretty impressed so far. I've been doing basic stuff just to get used to my Tascam DP-01 and the Bluetube, trying out different levels, etc. I recorded some Black Crowes riffs with a close mic'd SM57 and one of my good friends thought I was playing the actual studio track! I also have a quick question about powering condenser mics. I picked up the Marshall MXL 990/991 set, and I was wondering...Can I split the signal on one channel and power two mics? or will the 48v only power one mic at a time? I'd like to essentially run the 990/991 together with the SM57.
