doepfer System A - 100 Quantizer A-156

1. Introduction
Module A-156 (QNT) is a dual control voltage quan-
tizer.
For each of the two sections, the control voltage ap-
plied to the input is converted into the nearest quanti-
zed (i.e. terraced or stepped) voltage, and sent to the
control voltage output. Any voltage between 0 and 10V
is acceptable.
Quantizer 1 provides the usual semitone grid (i.e.
steps of 1/12 V) whereas quantizer 2 enables more
elaborate grid settings like major or minor scales or
chords. If desired quantizer 1 can use the same grid
settings as quantizer 2.
The trigger inputs allow the synchronization of the
quantizing processes to other events (e.g. envelope
trigger, analog sequencer clock, MIDI clock).
The trigger outputs transmit a trigger pulse whenever
quantization takes place.
The transpose input is common for both quantizers
and enables the transposition of both output voltages.

3. Basic Principles
A quantizer consists of an analog/digital converter
(ADC) and a digital/analog converter (DAC). The vol-
tage applied to the analog input of the ADC is conver-
ted into digital information (e.g. 6 bit = 64 steps). The
DAC converts this digital information back into a quan-
tized analog voltage in the same voltage range. For
pitch control voltage applications following the 1V/oct
standard an ADC resolution of 1/12V (= 0.0833V) is
used.
Module A-156 contains 2 quantizers. The factory set-
ting for quantizer 1 is a semitone grid (i.e. voltage
steps of 1/12 V, see fig. 1).
H If the position of jumper J1 on the A-156 circuit
board is changed the first quantizer has the
same features as quantizer 2, i.e. the 3 switches
determine the behaviour of quantizer 1 as well.
Quantizer 2 enables other grids than just semitones,
e.g. major scale, minor scale, major chord, minor
chord, fundamental + fth and the addition of a sixth or
seventh to chords. This means that only such voltages
appear at the control voltage output that meet the
selection criteria (e.g. minor chord with seventh) set by
the 3 switches.

Quantization takes place continuously if the trigger
input of the quantizer in question is not used (i.e. if
nothing is plugged into the trigger input socket). The
internal quantizing rate is about 500 Hz in this case. If
a rectangle signal is applied to the trigger input (e.g.
from an LFO, sequencer trigger output, MIDI-to-Sync
interface) the quantization happens only during the
low/high transition of the trigger input signal. Thus the
quantization process can be synchronized to other
events.
