ABC

6 channel mixer

ABC is simple 6 channel signal mixer. It has 6 inputs A,B,C,D,E and F and two outputs A+B+C which is mixed in to the D+E+F output if nothing is inserted in the A+B+C jack. ABC is designed to mix audio signals but can be modified to mix CV signals instead. There are 6 solder jumpers from the back side which can be connected to turn the abc mix into CV mixer.

There are 3 jumpers on the back side which would normalize inputs A to D, B to E and C to F which can be useful if you would like to use the abc mix as a 3 channel stereo mixer (using both outputs and having separate volume control for left and right channel).
