Description

Doepfer's universal vactrol module in 8 HP: two pairs of voltage-controlled resistors, to bring voltage control to any parameter set by a potentiometer.

Key features

Two units, each a pair of vactrols whose resistances change together
Man. knob and CV In with its polarizer, a LED showing the vactrols' light
VAC1 and VAC2 give the resistors' two terminals, not grounded: soldered across an envelope's decay, a slew limiter's time or a guitar pedal's potentiometer
For users at ease with a soldering iron; low voltage devices only (40 V at most)
