ABC is a simple 6 channel signal mixer.
It has 6 inputs A,B,C,D,E and F
and two outputs A+B+C and D+E+F.
A+B+C is mixed into the D+E+F output if nothing
is inserted in the A+B+C jack, which means
it can either work as 2x 3 channel mixer
or one 6 channel mixer.

ABC is designed to mix audio signals, but it can
be modified to mix CV signals instead.
There are 6 solder jumpers on the back side which
can be connected, to turn the A+B+C mix into
a CV mixer. Those solder jumpers bypass the input
capacitors, therefore changing DC coupling into
AC coupling
)
There are 3 jumpers on the back side which
normalize inputs A to D, B to E and C to F.
This can be useful if you would like to use the
A+B+C mix as a 3 channel stereo mixer, by using
both outputs and having separate volume
controls for the left and right channel.
