Doepfer A-174 Joystick (used)

Module outputs 2 control voltages generated by a spring-loaded X/Y cross potentiometer (so-called 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. Because of the circular mechanical control range it's not possible to obtain both the maximal and minimal values for X and Y simultaneously. Example: the 3 o'clock position of the lever corresponds to the maximal X value. Moving the lever upwards (towards 1:30 o'clock position) or downwards (towards 4:30 o'clock position) lowers the X value due to the of the circular mechanical control range of the lever. As the joy stick used in the module is no longer manufactured we have to stop the production of this module.
