Doepfer A-174-1 Joy Stick
Module A-174 modules outputs 2 control voltages generated by a spring-loaded X/Y cross potentiometer (so-called joy stick). For each output the voltage offset (zero setting) can be adjusted. Each output is equipped with 2 LEDs for positive/negative display of the output voltages. If the spring is removed for one direction the joy stick is no longer spring-loaded for this direction (as the spring is destroyed when removed this cannot be re-established !). We use a high quality joy stick made by ALPS in the A-174.
Application: manual X/Y CV control of other A-100 modules, e.g. VCF, VCA, VCO, Phaser, BBD modules, wave shaper/multiplier, frequency shifter, VCLFO, VCADSR, panning, etc.
In combination with the Dual Voltage Controlled Crossfader A-134-2 manually generated crossfades between audio or modulation sources can be realized.

The pcb is equipped with two jumpers that can be removed to obtain a voltage plateau around the center position, i.e. the output voltage does not change for a small movement range. The jumpers are labelled JP4 (Y plateau) and JP5 (X plateau). Removing the jumper activates the plateau. The following picture shows the position of the jumpers: A174_1_jumpers.gif
Width: 10 TE / 10 HP / 50.5 mm
