I bought a used DP01FX some time ago and I can't get decent input volume. I'm using a Shure SM-57 and to record acoustic guitar, for example, I have to turn the input trim pot almost all the way up, which is very noisy and produces a boomy sound. I also bought a mic ART TubeMP Tube Microphone Preamp, but it doesn't seem to help.
Any ideas out there? Has anyone else ever seen this issue?
