sheer sonic power.
The renaissance of analog synthesizers in the
last few years shows that analog sound
generation has its qualification besides
sampling and digital synthesis and creates
sounds that are available in no other way. In
addition to the specific sound of analog
oscillators and filters, this system offers
manifold ways of modulations, not being
restricted to conventional types.
But even if you have a lot of time, you should
acquire some theoretical previous knowledge.
However, if you have cleared all these hurdles,
the fascinating world of a modular system will
appear to you, and you will understand the
musical attraction of analog sound synthesis
very soon.
Of course we hope that these remarks will not
get you off the A-100. But we think that some

12dB multimode filter based on the filter circuit of the Oberheim
SEM module, band pass and combined low/notch/high pass
output, a control knob defines the relation between low and high
pass signal for the combined output (center position = notch),
no self oscillation (in contrast to most of the other filters of the
A-100 system), audio signal distorts if the level control is set to
about center position or more. The function and operation of
this module is very similar to the Wasp filter module A-124. But
the sound of both filters is very different !

a very special filter that has it's origin the MS20 filters. Can be
used as a 12dB low pass and 6dB high pass simultaneously
with two different audio inputs and a common output. Sensitive
audio inputs for distortion effects. The positive/negative limiting
can be adjusted manually (CL+/CL-, incl. option for ext. vactrol
connection). Two different CV inputs: one with attenuator, one
with polarizer. The low pass audio input is normalled to the high
pass input which is equipped with a polarizer to obtain filters
similar to band pass and notch by adding or subtracting the low
and high pass input shares. Resonance control up to selfoscillation, resonance insert feature to insert other modules into
the resonance path. All in all the A-106 it is a very unique and
strange filter and has a lot of life of its own. Much more detailed
information incl. sound examples is available on our web site.

available on our web site
Morphing is possible only within one group. Between filters of group 1/2 only "hard" switching is possible.
Of course all standard filter functions are available: frequency and resonance control manually and by an external control voltage (2 CV inputs
available, one with attenuator). For the 18 filters of group 1 self oscillation is possible. The filters of group 2 do not support self oscillation.
On top of this a final VCA with manual and CV control is available. This VCA can be used e.g. to compensate different audio levels (e.g. morphing
from low pass to high pass will cause a level change for high or low frequency settings).
Selecting a single filter, programming and selecting the filter chains is carried out with a 3-digit display, 4 buttons and a rotary encoder.
More detailed information about the module (with frequency response curves, sound examples, patch examples, complete user's manual) is

4 separate so-called subharmonics (this term was
first used in the Trautonium by Oskar Sala),
relation of the frequency of each subharmonic is
adjusted with up/down buttons in the range 1...24
and is displayed with 2-digit LED displays, rectangle master frequency input (e.g. from A-110/111),
sawtooth output, single and mix output, two gate
inputs to switch between 4 different “mixtures”, 50
user defined presets with 4 different mixtures,

Dual Ring Modulator
2 separate ring modulators; a ring modulator
generates the product X*Y of two audio input
signals X and Y (four quadrant multiplier);
consequently the output signal contains the sum
and the difference of the input frequencies; used
for generating the typical ring modulator and
frequency transforming sounds, normally used in
combination with 2 VCOs but also in combination
of a VCO with an external signal (e.g. via A-119)

Module Overview
Description
AUDIO DIVIDER
frequency divider for audio signals; preferable the
rectangle output of a VCO is used as input but in
combination with A-119 even clean monophonic
external audio sources can be used; mixer for
original (= input signal) and the next four octaves
below (outputs = symmetrical rectangles);
typical application: generating sub-octaves for
powerful bass sounds, alienation effects for
external audio sources, for strange inharmonic
effects even non-monophonic signals can be
divided (e.g. polyphonic or noise, preferable from
the digital noise generator A-117)
WP - VC Waveform Processor
dynamic waveform processing by clipping and
asymmetrical amplification of clipped and
unclipped signal; manual control and modulation
inputs for clipping level and symmetry; application:
generating new waveforms with dynamic variation
of the waveforms via clipping and/or symmetry
control inputs
The A-116 is similar to the A-136 but has only two
voltage controlled modification parameters
(clipping and symmetry). However these are
voltage controlled in contrast to the A-136.

A-102: Diode Low Pass 1 (VCF 9)
ladder with diodes instead of transistors as used
e.g. in EMS filters
For all modules: 3 CV inputs for filter frequency, 2
with attenuators, audio input with attenuator,
resonance up to self oscillation
24 dB Low Pass 2
another low pass filter with 24 dB/oct slope but
with a distinctly different sound and resonance
behaviour compared to A105 or A-120; the A-122
is built with a CEM circuit and works with the socalled OTA principle (like most of the Oberheim
filters); resonance is adjustable up to self
oscillation; manual frequency control and two
frequency modulation inputs (one with attenuator);
manual control and one modulation input with
attenuator for resonance (i.e. voltage controlled
resonance); audio input with attenuator.

Wasp Filter (VCF 5)
12dB multimode using the “strange” filter circuit of
the “EDP Wasp” (analog synthesizer with
black/yellow case built end of the seventies); this
design “abuses” digital inverters as analog
operational amplifiers leading to distortions and
other “dirty” effects that generate the specific
sound of this filter ; band pass ouput,
low/notch/high pass output with adjustable relation
of low and high pass signal (if both signals appear
one obtains a notch filter); resonance control (but
no self oscillation)

Dual linear/exponential VCA
two identical voltage controlled amplifiers, each VCA has a
manual gain control and a control voltage input with attenuator,
the character of the control scale can be switched to linear or
exponential, all inputs and outputs are DC coupled,
consequently the VCAs can be used to process both audio and
control voltages, the input has no attenuator available but is
capable to process up to 16Vss signals (i.e. -8V...+8V) without
distortion.
The module will be manufactured as long as the special
integrated circuit (CEM3360) is available.

the signal inputs are normalled, in addition the sum of all four
outputs is available, the full amplification range is about -90dB
... + 20dB (for attenuations below -60dB a negative and for
amplifications beyond 0dB a positive CV more than +5V is
required), for all C1 inputs trimming potentiometers are
available to adjust the control scale for other voltage ranges

Description
two identical voltage controlled crossfader units, in/outputs are
DC coupled, i.e. the module can be used for both audio and
control voltage signal processing, each unit has two VCAs with
opposite control behaviour available
Two types of control voltage behaviour (internal jumper):
Symmetrical: both VCAs have 50% amplification @ 0V CV. If
CV becomes positive the amplification of VCA1 increases and
VCA2 decreases. Useful for bipolar CVs (e.g. LFO, joy stick)
Asymmetrical: VCA1 is fully closed and VCA2 has full 100%
amplification with zero CV. If the applied CV becomes positive
the amplification of VCA1 increases and those of VCA2
decreases. Useful for positive CVs (e.g. ADSR, Ribbon)

Distortion and waveshaping module with extensive control
possibilities. The incoming signal is internally divided into 3
components:
•positive component with adjustable clipping level
•negative component with adjustable clipping lev.
•original signal
The 3 parts are mixed to the module output with adjustable
amplification (positive and negative) for each component.
Different settings of the 5 parameters enable a lot of very
complex and extreme waveform modifications: from simple soft
or hard clipping to completely altered waveforms

multiplies the waveform of an audio signal (e.g. VCO triangle)
within one period by folding and generates additional harmonics
(kind of "inverse low pass"); the period time and consequently
the pitch remains unchanged (in contrast to frequency
multiplication with A-196); for all 4 parameters manual controls
and CV inputs are available:
Multiples: number of waveform multiplications within one period
Harmonics: Adding more harmonics (similar to filter resonance)
Level/Symmetry: value/symmety of upper/lower folding level

Module A-137-2 is another version of a wave multiplier. In
contrast to the A-137-1 Wavemultiplier I the A-137-2 generates
four phase-shifted copies of a VCO signal (saw, triangle or sine
waveform) applied to the audio input. The four shifted signals
are added to the original signal to obtain a fat sound equivalent
to five independent VCOs. For each of the four additional
signals a manual phase shift control and a CV input with
attenuator is available. A suitable CV source is e.g. the Quad
LFO A-143-3. Details about the working principle of the A-137-2
including sound examples are available on our website
www.doepfer.com/A1372.htm.

four channel mixer, that allows to add or subtract four incoming
voltages to the output signal with adjustable level (in the middle
position of the corresponding control the amplification is zero;
counterclockwise: signal is subtracted, clockwise: signal is
added to the output sum); output control works in the same
way; control In1 works as a DC offset generator (about 5V...+5V) provided that no patch cord is plugged into socket In1.
Applications: mixing control voltages (e.g. ADSR, LFO) or audio
signals with fixed phase relations

Matrix mixer with four rows (1 - 4) and four columns (A D), switches for unipolar/bipolar mode for each column.
Unipolar means that the controls of the column in question
work as attenuators. Bipolar means that the controls work
as polarizers. In this mode the amplification is zero in the
middle position of the corresponding control. Turning the
knob counterclockwise from the center position the signal
is subtracted from the output sum with increasing amount
(i.e. negative). Turning the knob clockwise from the center
position the signal is added to the output sum with
increasing amount. As the module is DC coupled it can be
used for both control voltages and audio signals.

Module Overview
Description
Quadrature LFO/VCO
the term "quadrature oscillator" means that sine and cosine
outputs are simultaneously available, used e.g. for frequency
shifter, special control voltage (crossfading/morphing) or FM
synthesis applications, in addition the module has the
inverted sine and cosine available, the four outputs can be
treated as four sine waves with 0, 90, 180 and 270 degrees
phase shift, a range switch is used to select three frequency
ranges: slow LFO (minute range), LFO (Hz range), VCO
(moderate audio up to some kHz), approx. 1V/Oct scale (not
as exactly as a VCO)

control voltage modifier, in the first place used in combination
with the voltage controlled mixer A-135, from an increasing
input voltage four displaced triangle output voltages are
derived, when these outputs are connected to the CV inputs
of an A-135 one obtains a fading over of the four A-135 audio
inputs ("morphing"), morphing can be controlled manual and
modulated with an external CV (e.g. from LFO, ADSR,
Random, MIDI-to-CV, Theremin, sequencer) with attenuator.
Applications: voltage controlled morphing of 4 audio sources
in combination with A-135 (e.g. four different waveforms of a
VCO, 6/12/24/48dB slope of A-108, four different filter
outputs of a multimode VCF)

S&H Input
a control voltage (manually and CV) defines an address 1...8
that is used to address three different subunits: 8-fold
Sample&Hold, elektronical rotary switch, digital output.
S&H: The voltage at the common S&H input is passed on to
the addressed S&H output and stored at this output as soon
as a new address is generated. Switch: The common terminal
is connected to the currently addressed terminal (bidirectional). Digital out: The currently addressed output is
high (~ +12V) and the corresponding LED is on. The
remaining 7 outputs are low.
Instead of CV controlled addressing even Clock/Reset control
is possible. CV has to remain unchanged in this mode.

internal voltage controlled clock generator with manual tempo and CV controlled tempo (with
attenuator), clock display with LED, the internal clock is normalled to the clock input of the control
section, if the CV input of the clock unit is connected to one of the CV outputs of the A-155 the time
for each step can be adjusted separately, even jumps (step skipping) are possible as beyond a certain
level the clock unit generates an immediate jump (i.e. a very short clock signal), for this skipping
function e.g. the gate row of the A-155 can be used.
manual and CV controlled pulsewidth (PW) of the clock generator, this function allows gates with
different length for each step (but with the same tempo), one of the CV rows of the A-155 can be used
for this feature or external modulation sources like LFO or random CV.
8/16 step mode: the "16 step" mode requires two A-155 and at least one voltage controlled switch A-150 to switch between the CV/trigger/gate
outputs of the first (1...8) and second A-155 (9...16). The A-150 is controlled by the A3 output of the A-154.

Clock Divider
Trig.
In
frequency divider especially for clock/gate/trigger signals,
for example if lower (i.e. divided) clock frequencies are
required in the system for synchronising purposes;
especially for rhythmic sounds, the clock input may be
supplied from a MIDI-to-SYNC interface (for MIDI
synchronised timing) or from an LFO output; a pulse at
the reset input resets all outputs to zero (e.g. reset or
start/stop output from MIDI-SYNC interface)

Description
A-163 Voltage Contr. Divider
frequency of the input signal (e.g. rectangle from a VCO)
is divided by an integer factor N (1 . . . 20). N can be
adjusted manually and modulated with an external
control voltage (e.g. LFO, ADSR, Random, Theremin,
sequencer) with attenuator. Output waveform is
symmetric rectangle. In contrast to A-113 the dividing
factor of the A-163 is voltage controlled.
Applications: dynamic voltage controlled frequency
division of audio signals (you will find more details
regarding frequency division of audio signals in the A-113
information).

each unit:

3 momentary push buttons generate three gate signals
(+12V while button is operated, 0V when released), Gate
1 is different: if any signal (e.g. rectangle output of an
LFO) is connected to the input socket the gate button 1 is
working as a momentary on/off switch that turns the
signal on/off, each Gate output has two sockets
available, an internal jumper can be used to connect
Gate 1 or Gate 2 to the gate line of the internal A-100
bus, that way the module can be used to trigger one or
more envelope generators (ADSR A-140) that are
connected to the bus.

Analog Comparator
compares analog voltages and derives a gate signal;
internally the module generates the voltage k1*(+In) k2*(-In) + Offset (available at the output analog sum) and
und sets or resets the gate output depending on the
result of this internal voltage (>0V or <0V). k1 and k2
represent the manual attenuators. A LED shows gate
state.
The Gap control is used to adjust a so-called "hysteresis"
(i.e. the difference between on and off level). As soon as
the Gap control is turned up the switching levels for on
and off state fall apart.

The main application of the module is the
processing/mixing of control voltages, e.g.
random voltages, ADSR, LFO, S&H, ribbon
CV, theremin-CV and similar - or the
generation of new VCO waveforms by using
the outputs of a VCO as A-172 inputs. To
adjust offset and amplitude for each input
independently we recommend to combine the
module with the A-129-3. The sketch shows
the basic principle of the max/min module by
means of three sine waves (e.g. three LFOs)
with different frequencies and different levels.

output is a DC voltage that is adjusted with the Offset control
(0...+5V/-5V...+5V jumper selectable). It is overlaid by the
attenuated/ polarized voltage that is fed to the In socket.
Attenuator mode: control works as an usual attenuator,
Polarizer mode: zero level appears at the center position,
right from center the signal is added to the DC, left from
center the signal is subtracted from the DC offset.

Amplifier
simple DC coupled amplifier, suitable for CV and audio
signals, the maximal amplification can be switched between
1, 2 and 4, the actual level is adjusted by means of the Level
control between zero and the chosen maximim amplification
(1/2/4), two overload LEDs indicate if the output signal
exceeds about +10V/-10V.
main application: adaption of differing audio or CV levels
between modules or systems (e.g. LFO, ADSR or Gate
levels between modules of different manufacturers). Even
audio signals can be attenuated/amplified but the module is
not planned as an amplifer for external low level audio
signals (e.g. microphones or electric guitars)

extremely versatile module with a tapped BBD
(bucket brigade device) as its core. Each of
the six taps has two level controls available to
add the corresponding tap output positive or
negative to one of the two mix busses. Each
mix has a separate wet/dry control. The
clock/delay range is similar to the A-188-1 (i.e.
extreme wide range, manually and voltage
controlled). One of the mix outputs or a single
tap can be used for the feedback loop (default
= tap #1). Because of the 6 taps and the two
mix busses very complex and dense BBD
effects can be realized - even in stereo. Even
the standard BBD effects are possible
(flanging, chorus, analog delay, reverb) but
with extreme possibilities.

Voltage Controlled Bit Modifier
The module offers several voltage controlled bit modification
functions like voltage controlled bit crunching, bit shifting, bit
exchange, digital ring modulator and others. It has two units with
manual control and CV input with attenuator: One for the bit
manipulation function (e.g. bit crunching) and another for the
sampling rate (SR and SR CV).
The signal input is equipped with an attenuator. As the module is
DC coupled even control voltages can be processed. The mode
(e.g. bit crunching, bit shifting, bit exchange) is selected by a 16position rotary switch.

play manual modeled on the Trautonium; made of a very sensitive position
sensor that is activated by touching the sensor with the finger. It generates
a voltage that is changed by moving the finger. Below the position sensor
the pressure sensor is located. It is much less sensitive and generates a
voltage that depends upon the pressure generated by the finger. For
both voltages the scale can be adjusted and two gate signals are
derived (with adjustable threshold for the pressure section).

The functions of the module are very complex and not very
easy to understand for beginners because of the closed loop system with several parameters.
Beside the "classic" PLL application the module invites to experiment by changing all the PLL
parameters (filter frequency of the low pass, detector type, VCO range) to find out the results.
Even the insertion of other modules is possible. E.g. with the A-163 voltage controlled frequeny
multiplication is possible (sort of VC harmonics). Inserting a VC slew limiter allows voltage control of
the "delay" time or "portamento" of the internal VCO.
Applications: special sound effects, frequency multiplication, generation of clock signals for graphic
VCO (e.g. high speed VCO für A-155) or switched-capacitor filters

(same power supply quality as A-100 PSU2,
but external transformer)
The A-100 DIY kit #1 is a combination of components that allows the
inexpensive do-it-yourself construction of a case for the A-100. Because
of safety reasons, no dangerous voltages are accessible because of
the usage of an external transformer (AC output). The kit includes two
bus boards, four 84 HP mounting rails with threaded inserts for module
mounting (sufficient for 2x3U), all cables required for connections
between power supply and bus boards. The max. output current is
1200mA. Sketches with measures (for drilling the holes at the right
positions for PSU and bus board mounting) and building suggestions for
wooden cases are included as well. Additional installation material like
screws, nuts or distant bolts (e.g. for bus boards, power supply board,
rails) is not included. Attention: from Doepfer (Germany) only 230V
transformers with European mains plug type are available (external
transformer with 15V/2.5A AC required), please ask the Doepfer
representative in your country if they have a transformer available that
is suitable for the mains voltage and mains plug in your country

A-100 Planning
In the following you find some information concerning
the construction of the A-100. When you order one of the
basic systems you will not have to deal with these
details. But if you want to put together your own specific
A-100 system this information will help you for your
planning. For this mechanical and electrical aspects
have to be taken into account. The mechanical aspects
refer to the width of the modules, the electrical aspects to
the power consumption of the modules. If you want to
built your own system a bit technical experience is
required. Otherwise we ask you to order the system
ready assembled according to your given data.
On our web site we have some files available for
download that make the A-100 planning a bit easier: a
TM
flash based module planner, an Excel file for automatic
calculation of total current and total width of the desired
modules, two picture files with all A-100 front panels (one
as pixel pictures, the other as vector graphics in Corel
TM
Draw format)
Mechanical Aspects
The construction of the A-100 modular system is based
on the international standard 19" rack system (DIN
41494 / IEC 297-3 / IEEE 1001.1). First of all an empty
frame with power supply and bus boards is required.
This can be filled with the desired modules. The
standard 6U frame (A-100G6) consists of two sections
each 3U high, tied together by 6U side panels (see
picture on the right side). It contains two bus boards, a
power supply with +/[email protected] (PSU2), the main
electrical supply socket and all interconnections
between these parts. Other versions of cases are
available too (e.g. portable versions with 6U or 9U, open
low cost versions with 6U and 9U, large "monster"
suitcases with up to 12U and 168 HP, see separate page
A-100 Housings).
Module front panels are all 3U high (1U = 1.75 inch =
1.75" = 44.45mm, 3U = 133.4 mm). The final height of
the front panels is a bit less than 133.4 mm as the rim of
the mounting rails has to taken into consideration.
Consequently the final height is 128.5 mm for all A-100
front panels. Their width is measured in HP (HP =
horizontal pitch, 1 HP = 5.08 mm or 1/5 inch or 1/5"). The
actual width of a front panel is a few tenth of a mm less
than the calculated value (i.e. multiple of 5.08 mm resp.
multiple of 1/5") to have a little bit tolerance to assemble
the panels. The table below shows the actual widths for
the most common front panel measures and the position
of the mounting holes relative to the front panel edges.
For the front panels up to 10 HP normally 2 mounting
holes are sufficient (one below, one above). From 10 HP
normally 4 or even more mounting holes are used. The
horizontal distance of the mounting holes has to be a
multiple of the HP grid, i.e. a multiple of 5.08 mm resp.
1/5" (= N x 5.08 in the sketch below). To assemble the
modules in the frame M3x6 oval-head screws with cross
recess (DIN7985) are used. The front panels are made
of 2 mm anodized aluminium.

Technical Notes
Analog Modular System A-100
The standard rack system has a usable width of 84 HP
(= 426.4 mm). Individual modules can be fitted in any
chosen layout into the 19" frame. If the modules don’t
use up the entire 84 HP, then the spaces have to be
covered with blanking panels due to safety and EMC
reasons. We offer blind panels with 1, 2, 4, 8 and 42 HP.
In the description for each module (e.g. A-110-1) the
width of the module in HP measures can be found.
For the A-100G6 we use frames from the German
company Gie-Tec (www.gie-tec.de). Frames from other
manufacturer that meet the 19" standard can be used
normally as well. If you want to built your own frames or if
you need additional accessories you may order directly
from Gie-Tec. We do not offer single mechanical parts
but only completely assembled A-100 frames with built in
power supply and bus boards.
Electrical aspects
The A-100 modules require the power supply voltages
+12V and -12V, a few modules from other
manufactureres may also need +5V. The voltages are
generated by the A-100 power supply A-100PSU2 and
distributed to the bus boards. The A-100PSU2 has
available 1200mA for both +12V/-12V and a ring core
transformer for lower mechanical and electrical noise.
The signals +5V, CV and Gate are used by only some of
the modules (see module description for details). CV
and Gate are not required unconditionally since these
signals may be supplied via front panel connectors too.
These bus signals are supported only by VCOs, some
envelope generators, bus access modules and MidiCV/Gate interfaces.
For each module, the assembled flat cable required for
connection to the bus is included; cables for front panel
connections (patch cords) are not included and have to
be ordered separately.
The required supply current is the sum of the currents of
all modules in the frame (e.g. A-100P9). The current of
each module is specified in the module description.
Normally, the power supply A-100PSU2 is sufficient for a
6U or 9U system if not too many power consuming modules are used in the same system (e.g. too many A-110-2).
For modules that require +5V the plug-in adaptor A100AD5 is available (max. current 100 mA).
All cases available from us (A-100G6,A-100P6/P9/PB,
A-100LC3/LC6/LC9/LCB and the A-100 monster cases
A-100PMS6/PMS9/PMS12/PMD12)) are completely
assembled and tested. They include the power supply
(+/-12V), bus boards, rear, top and bottom covers. At the
rear panel the power supply, the mains inlet, power
switch and fuse are located.
For applications with only one or a few modules the
miniature power supply with integrated bus board (A100MNT) is available. The A-100MNT deliveres +/-12V
(200mA) and +5V (50mA) and has 4 bus connectors.
The A-100MNT runs with a standard AC adapter (9V AC
output) and uses no dangerous voltages - in contrast to
the A-100PSU2. The A-100MNT is also available with a
small case (A-100 Miniature Case A-100MC).
A-100PSUII
Each bus board is equipped with 14 double row
pinheaders with 16 pins. The following signals are
assigned to the bus board pin headers: -12V, GND,
+12V, +5V, internal CV and internal Gate.
Each module is equipped with dual row pin header (10 or
16 pins). The connection between a module and the bus
board is made with a 10 or 16 pin flat cable, having
socket connectors pressed on each end. 10 pin cables
only lead -12V, GND and +12V, the 16 pin cables also
lead +5V, CV and Gate.

For DIY applications we have the A-100 DIY kit #1 available. It uses an external supply, i.e. there are no dangerous voltages acessible.
You may also purchase the bus boards and power supply A-100PSU2 separately so that you could use other frames. These devices are allowed to be installed only
by qualified personnel because of the electrical safety (230 or 115V mains voltage).
Self-building of frames is recommended only for customers who are familiar with electronics because of
the electrical safety !

Analog Modular System A-100 Complete Systems
A-100 Basic Systems
There are no fixed rules for which and how many
modules are required in an analog modular system. If
you are a beginner, you might have problems in finding
the right combination of modules for a basic system.
Thus, we have arranged a few system packages to start
with, containing the modules in the table on the right.
The main difference between the basic systems 1 and 2
is the MIDI interface. System 1 is not equipped with a
MIDI interface. If you want to control this system with
MIDI you need an external MIDI-to-CV interface (e.g.
MCV4). System 2 contains the MIDI interface A-190-4
instead of the two modules A-150 (Dual VCS) and A-162
(Dual Trigger Delay).
The modules are completely mounted into a 6U base
frame and each system contains 30 cables (mixed
lengths). The systems are available also as portable
suitcase versions (with mains inlet on rear or front
panel).
You will save some money compared to the regular
prices when you purchase one of the basic systems!
The purpose and function of the other modules not
included with the basic systems will become clear while
you are working with the A-100 system, and you will
realize the missing modules for your application very
soon. If you plan to expand the basic system we
recommend to order the system already in a bigger case
(e.g. A-100P9). Then there is an additional row left for
future modules. But you may continue also with another
additional frame (e.g. A-100G6 or A-100P6/P9 or A100LC6/9 or one of the monster cases or the monster
basic frame) and the desired additional modules and
patch cords.
The special prices are valid for these combinations
only (no exchange of modules) !
On our web site we have some more suggestions for
complete systems available, e.g.
! Small Starter System
! Miniature System
! Expansion Systems for the Basic Systems
! Sound Processing Systems
! Trautonium System
! Theremin Systems
! Sequencer/Sampler System
and many more
For the planning of a system we have several tools
available on our website:
! Excel planning sheet (with module widths and
currents)
! different Java or Flash based module planners with
pictures of the planned system
If you want to plan your specific system we ask you to
pay attention to the remarks on the following pages.

Technical Notes
Analog Modular System A-100
MIDI Integration of the A-100
For integrating the A-100 into a MIDI system, the internal MIDI interfaces A-190-2, A-190-3, A-190-4, A190-5, A-190-8, A-192-1 and A-192-2 or the external
interfaces MCV4, MSY2 and Dark Link are available.
The MIDI analog sequencers MAQ 16/3 or Dark
Time are the right choice if you love analog sequences
controlled by MIDI. They are equipped with CV and
Gate outputs which are compatible with the System A100. Due to the MIDI and USB features they have
some different features compared to A-155.
Even some of our OEM products (e.g. MTV16,
CTM64 , MTC64 , Pocket Electronic, Wheel
Electronic, USB64, MKE, MBP25) can be used in
combination with A-100 to transmit or receive Midi
data. For example the MTC64 can be used to generate
up to 64 gate signals controlled by Midi note messages
and the MKE can be used as a keyboard to control the
Midi interface A-190-4.

Prices
The prices for single modules do not include installation
fee, user's manual and patch cords. The installation fee
for one module is specified in the price list. We recommend to order only completely assembled and tested systems. Only experienced users may order single modules
with separate frames and assemble the modules in the
frames themselves.
The module prices are valid for orders of single modules.
If you order modules together with a basic frame, the
modules will normally be installed into the frame, paying
regard to your wishes for configuration. In this case the
mounting fee per module has to be added. Only if you
wish the modules expressly unassembled we ship the
modules and the frame separately.
Modules or systems do not include user’s guides. These
are available for free download from our website. The
complete user’s guide is available also in printed form
(additional charges).
Handling and shipping charges, import duty and tax are
not included in the prices. These depend upon the country, distance, weight and type of shipment. If there is a
Doepfer representative in your home country you have to
order from the representative (please look at our web site
www.doepfer.com -> DEALERS for details).
