I'm new to setting up gear and I'm trying to figure out how to set up my board to my computer so I can record 8 tracks into pro tools, then play back from pro tools and mix on my board. Heres what I did. I have a mic line going into the board, then the direct outs going into my Delta 1010's input, and that going to my PC. I'm recording just fine. Then I put the direct outs of the Delta 1010 to the 25-32 track inputs of the board so I can mix on the board afterwards. The problem is, when I hooked up the outputs of the delta 1010 to inputs of 25-32, I'm getting a constant hum in every channel. Whats the best way to record into pro tools from a 24-48 channel board and have my mix play back through 25-48 or just through the speakers. Heres my gear: Eurodesk MX9000 Delta 1010 x1 (I plan on getting one or two more once i figure out the problem) A PC I built running pro tools m powered 8. A pair of Alesis M1 active speakers. Also I want to run the sound too the speakers from the board. Should this be going out of the main mix outs or the main balanced outs? Here are some pictures of whats going on.
