Hello all, I have, what I hope will be, a simple question: I have an MBox 2 hooked up to my MacBook Pro via USB. I have my PreSonus TubePre hooked up to my MBox 2 via 1/4" cable (Unbalanced out from TubePre to Line (TRS) input 1 on MBox 2). I have my Sterling Audio ST59 mic plugged into the Microphone input in my TubePre. My Mbox has power, my TubePre has power and the phantom power (+48V) is turned on on the TubePre for the mic. When I open ProTools 8 LE, no sound seems to be registering through the microphone. When I hit record, the tracking bar moves but it doesn't seem to be recording anything (no colored block appears following the tracking bar as it moves). Help? Maybe I need to change some inputs somewhere? Do I have things hooked up incorrectly? Any advice would be greatly appreciated. Thank you!
