I got the adm 2783 and 1540 combo off ebay and have been trying to wire it, but since it is my first mic pre wiring project, i have run into a lot of problems and probably wasted some money too.
I know the schematics aren't handy (i'll try to scan them for you dave), but hopefully my question can be answered without them.
I have run both logic power (24V) and audio power to the units, and the eq will turn on (the light will come on), but the mic pre will not. For obvious reasons, i feel like it has to do with a pin marked "EXT ON CNTL", but i have tried applying voltage and tried grounding it (with it switched to on), but nothing lights up and no signal is passed.
Has anyone heard of this EXT ON CNTL (i assume its a common automation thing) or know what to do with it?
thanks guys, sorry for the long winded post.
