Trying to set up my DM3200/ Logic to do some revamping. With some research on this forum, I can get the di signal out of the DM3200 now and to the ramp box. amplifier. I'm wanting to rout the microphone to an external mic preamp then its output into one of the Assignable returns and rout that into a channel in logic...How to I go about doing this? Thanks for any help.
