ok, im thinking about making a handful of these and would like a show of hands on who is in.
-4-pin mini xlr input, with 4-pin to (2) 3pin breakout cable.
-3 pin mini xlr output, with options for 3-pin to two xlrs or 3-pin to 1/8" mini
-4-pin extension cable (stereo) to allow you to run a single stereo cable up to where you y-it to the mics (my mics have 2m cables)
all cables will be shielded schoeps cables identical to the factory cmr (single channel) or kc5 (stereo) cables, switchcraft mini xlrs, neutrik full-size xlrs
battery box - $50
input y-breakout cable (short) - $50
3-pin mini xlr output cable to 2x straight or RA xlr - $50
3-pin mini xlr output cable to minijack - $35
4-pin extension cable - 5 meter kc5 style cable - $100
those are mostly materials costs, most of the mini xlr and xlr fittings are $10 each after shipping and the schoeps cable is up to $16/meter. so im not in it for the money obviously, making $20 or less per component. I am gonna make myself a second-gen unit and would rather bang out a few at a time, all universal so we can all get along in the field.
