I just got my DP-24SD today (and I've watched most of Phil's videos), and I am having what seems like an unusual problem. When I am monitoring a signal that I am preparing to record, the volume is extremely low. If I crank everything up (trim, digital trim, channel fader, stereo fader, monitor level) I can get it in the headphones, but it distorts. When I record audio with this setup and play it back, the volume is fine in the headphones. I have tried this both through the headphone jack as well as with the monitor out (using a headphone amp), and I have the same results with both options.
