1. Introduction
Module A-174 (Joy Stick) outputs 2 control voltages
generated by a spring-loaded X/Y cross potentiometer
(so-called joy stick). 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 !).
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.
Module A-174 is an universal two-dimensional control
voltage source to control the parameters of other
A-100 modules by hand, e.g. filter frequency or reso-
nance (VCF), loudness or modulation depth (VCA),
stereo-panning (A-134), quad-panning (2xA-134), pha-
sing (A-125), frequency shift (A-126), morphing (A-135
+ A-144), pitch bend (VCO), modulation speed (A-
147), decay (A-142) or other envelope parameters
(A-141) and many more.
A high quality joy stick manufactured by ALPS is used
in the A-174.
