doepfer System A - 100 NOISE / RANDOM A-118

1. Introduction
Module A-118 (NOISE / RANDOM) is (as you might
have guessed) a noise and random voltage genera-
tor.
It produces three types of signal: white noise, colo-
red noise, and random voltage.
White and colored noise can be used as audio sour-
ces, and also, in conjunction with a sample & hold
module, as control voltages, and the random voltage is
a useful source of voltage control, especially for its low
frequency content.
The A-118 gives you the ability to mix the relative
amounts of Red (low frequency component) and Blue
noise (high frequency component) in the colored noise
output.
There are knobs to control the rate of change and
amplitude of the random voltage, and two LEDs indi-
cate the state of the voltage at any one time.
