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
isinserted in the A+B+C jack, which means
it can either work as 2x 3 channel mixer
or one 6 channel mixer.
Each channel has its own gain knob.
Maximum gain is 1.
ABC is designed to mix audio signals, but it can
bemodified 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
aCV mixer. Those solder jumpers bypass the input
capacitors, therefore changing DC coupling into
ACcoupling
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.

Before connectin the ribbon cable to this module
disconnect our sstem from ower !
Double check the olarit of the ribbon cable and
that it is not shifted in an direction. the red cable
should match the -12V rail both on the module and
on the bus board !
lease make sure of the followin
you have a standard pinout eurorack bus board
you have +12V and -12V rails on that bus board
the power rails are not overloaded by current
Although we put protection circuits in the device,
we do not take any responsibility for damages
caused by wrong power supply connection.
After you connected everything, double-checked
it and closed your system, so no power lines can
be touched by hand, turn on your system and test
the module.
