Features

Attenuverter
- Va is the voltage input a for attenuverter (left jack on the panel)
- K knob can scale the incoming Va voltage either positively or negatively
Crossfader
- Vb is the voltage input b for the left side of the crossfader (second jack from the left)
- +.5 switch adds 5 volts to the input of Vb
- Vc is the voltage input c for the right side of the crossfader (fourth jack from the left)
- M scales Vb from 1 to 0 based on the position of M knob
- M scales Vc from 0 to 1 based on the position of M knob
- The middle CV input at M/M can crossfade between Vb and Vc (third jack from the left)
- The M knob and M CV added together to control crossfade position
Offset
- Voset Adds 0 - 10 volts to any combination of Va + Vb + Vc
Output
- Vout is the combined voltage of the attenuverter, crossfader and oset (right jack on the panel)
