Hello, happy holidays!! I have a question to see if anyone has experience with this mixer. I'm going DI 1-2 on my mbox from the mixer, so I can use the pre's on the mackie. I'm getting a hiss, low level but annoying. Is this normal or can I get around it somehow??The pre's on the mixer are much better than the mbox, that's why I want to use them. Is this a good idea or am I adding to much noise. If so, How can I eliminate some or all of the noise?? I'd appreciate any help!!
