Interfacing Drum Machines w/ High End A/D & Consoles?

Hey all,

I have a real problem here interfacing certain drum machines (early MPC series) with the +4 in's on the outboard ADs and certain Line summing consoles. The outputs are listed in the spec sheet at 6 dbm, 600 Ohm, but that level is relative to the internal level which goes from 0-200%. The default internal (pre d/a) output percentage is 100%, but at that level the eventual post d/a output is too hot for -10 and far to low to be usable at +4. When boosting the internal percentage to 200%, the output d/a in the drum machine distorts, though the level seems to be closer to the listed white sheet spec.


One that comes to mind is running the 8 outs through passive di's and regaining through mic pres.. but this seems a little redundant to me.

Maybe i'm missing something?

thanks in advance for the help.
