Doepfer A-134-2 Dual Voltage Controlled Crossfader
This module is used but in good working condition and has been fully tested.
The Doepfer A-134-2 has two identical crossfader circuits with variable response ranges selectable by a jumper pin. The CV inputs can operate in "symmetrical" bi-polar mode between -2.5 and +2.5 volts, or "asymmetrical" unipolar mode between 0 and +5 volts. It can also be used as a voltage controlled mixer.
