Hi guys. I was planning on getting the Digidesign MBox for my small project home studio to act as a analog / digital converter for Pro Tools LE. I noticed that the MBox has two mic preamps and TRS inserts as well. I don't need the preamps since I arleady have an anolog mixer. My question is, if I plug the signal into the TRS inserts from the output of my mixer, will it bypass the preamps and not affect or degrade the signal? I ask this because lets say I get a really good mic preamp later on. I don't want to have the signal turn to crap once it goes into the Mbox and onto my computer. I'm not sure what happens to the signal once it goes into the box, will it degrade the analog signal in anyway? I hope my question makes sense to you guys. Thanks.
