I am trying some new units out for vocal processing. I used an Antares AVP-1 for a few days which was very easy to use but sounds came through a bit weaker than when they went in. So now I have a DBX pro vocal unit which is more confusing. The first thing I can't figure out is: I send my signal from my 2480 to the unit and when it come back, it sounds like it has a slight digital distortion to it, even with everything bypassed. Input levels on the dbx and my console are in range. Could this be a side affect of using unbalanced patch cables? Or is this unit just junk? Whats going on? Is there any other De-Ess/vocal processing modules that anyone would suggest?
