12x12 Buffered Matrix
12 INS - 12 OUTS MATRIX
This module is a 12 ins and 12 outs precision buffered matrix.
It's conceived to be a semi-permanent matrix for medium to big systems, with white silkscreen labels to customize ins and outs names.
Every output has a rotary switch to select an input. You can make the same input go through several outputs but not several inputs go to the same output.
There's also a bi-color led next to every output for visual info of the signal that is going through it.
Allows fast patch changes and easy rerouting signals, both audio and cv.
Can be used as a traditional buffered multiple, pretty flexible one: 1 x 12 outs, 2 x 6 outs, 3 x 4 outs etc...
45 mA +12V
45 mA -12V
The build process it's pretty easy
place these holders under the leds so they're straight and closer to the panel
for the rotaries, place one nut or 5 washers under the panel too, so the portion of bushing and shaft over the panel will be shorter
solder a cable like in the image
