Hey everyone - first time poster here! So, the short story is that my new job wants me to trouble shoot a problem with their voice over studio. I have some experience as I have a very nice home studio and record a lot, but I am not a pro, and don't know all that much about voice over work. Here goes: We are using a Shure SM7B / MBox / SoundBooth setup and there is a problem with low level distortion. I know the SM7B is a great choice for voice over (industry standard), however, being a dynamic mic it's output is low. I am guessing that the pres on the MBoxes have some inherent distortion, and the volume difference between the signal level to the distortion level just isn't big enough to mask it. The distortion is through out the entire track, and doesn't appear to be related to digital overs (as far as I can tell), and I can hear it, albeit faintly, on the latency free monitoring on the MBox which means it's happening before the signal gets to the PC. It's not too loud... until the necessary compression goes on the track, and then it's problematic. I have tested the mic at home (works fine) and swapped cables (no improvement). I just think the Mboxes aren't up to this particular task. I am think we either need to a) run a separate higher gain pre before the Mbox and defeat the Mbox's pre (if even possible) or b) get a better interface with louder / cleaner pres. Or c) get a high gain pre and a new interface with defeatable pres. I am leaning toward the second option, but am not sure what interface would work best. I'd like to keep the mic (it's a very noisy room) if possible. I sure could use some advice from people who have worked with this mic before as to what to get. Oh, and I'd like to keep USB *if possible*, so as not to have IT freak when I ask them to install a card. Any advice would certainly be appreciated!
