Voltage Controlled Divider
Module A-163 is a voltage controlled audio frequency divider. The frequency of the input signal (preferably the rectangle output of a VCO) is divided by an integer factor N (N = 1, 2, 3, 4 ... up to 32). N can be adjusted manually and modulated with an external control voltage (e.g. from LFO, ADSR, Random, MIDI-to-CV, Theremin, Light-to-CV, analog sequencer) with attenuator. The control input has polarizing function, i.e. the manually adjusted dividing factor can be modulated upwards or downwards. The basic idea of a polarizer is described in the modules A-133 Voltage Controlled Polarizer and A-138c Polarizing Mixer.
The output waveform is rectangle with 50% duty cycle. Unlike the A-115 with fixed dividing factors (2, 4, 8, 16) the dividing factor of the A-163 is voltage controlled and can be any integer value between 1 and about 20 (but only one output). In contrast to A-113 the dividing factor of the A-163 is voltage controlled and the output waveform is rectangle (the A-113 has 4 sawtooth outputs with 4 adjustable but not voltage controlled dividers).
Applications: dynamic voltage controlled frequency division of audio signals or modulation signals. More details concerning frequency division of audio signals can be found in the Trautonium or A-113 information.
Inputs: CV In, Audio In (rectangle)
Output: Audio Out (resp. rectangle modulation CV out after modification)
Controls: Manual N, CV attenuator
After a small modification (a capacitor has to be shortened or replaced by a wire for DC coupling) the A-163 can be used for low-frequency control signals too.
