ABC

A six channel mixer in 5 HP, made by Bastl with Postsound: six inputs, A to F, each with its gain knob (at most unity), in two groups of three, to the A+B+C and D+E+F outputs. With nothing plugged into A+B+C, its mix joins D+E+F: two 3 channel mixers or one 6 channel mixer.

Key features

• Six inputs, a gain knob each, unity at most
• Two outputs, A+B+C and D+E+F, A+B+C mixed into D+E+F while unpatched
• AC coupled inputs for audio; solder jumpers on the back make them DC coupled for CV
• Jumpers on the back normalise A to D, B to E and C to F, for a 3 channel stereo mixer
