A-163 Voltage Controlled Frequency Divider (Discontinued)

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 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).

    The module is equipped with an additional jumper at the bottom side of the pc board. This jumper is used to select DC coupled (jumper installed) or AC coupled mode (jumper removed). If the module is used to divide slowly changing signals (like clock, trigger, gate or rectangle signals of an LFO) the DC coupled mode has to be selected. For audio signals the AC mode is recommended.
