SAFETY INSTRUCTIONS
Please read carefully before using:
• Only use the correct power adaptor - 230V (or 115V whatever your country needs)
• Never handle the adaptor with wet hands
• Never excessivly bend the adaptor cable or get it trapped or place heavy objects on it. If the adaptor cable
becomes damaged, replace the adaptor.
• Ensure the unit is disconnected from the mains before moving or cleaning.
• Always disconnect the unit from the mains if there is lightning in your area.
• Ensure the unit is on a stable surface, and never place heavy objects on top of it.
• Never allow young children or animals to operate the unit or adaptor.
• Do not use excessive force when using the controls or inserting cables to the connectors.
• The unit should not be operated in the rain or near water and should not be exposed to moisture. If the unit is
brought from a cold environment to a warm one, the unit should be left to reach the ambient temperature.
• Keep Concussor away from heat sources, such as radiators, ovens, heaters etc.
• Never allow Concussor to get wet. Do not operate it near water, like pools, sinks, bathrooms etc. Do not place
beverages on or near it.
• Never open the case or attempt to make repairs. Refer any servicing to a qualified service personnel.
Preventing damage to other connected devices
Concussor modules have a very high dynamic range. It is capable of produce loud signals of very high and sub-
sonic frequencies that could blow inadequate speakers if played too loud. It is recommended that input levels to external
equipement (mixers, amp's etc.) is kept low when first connected, and then sowly increased to a userable level.
Maintenance Instructions
Any cleaning of the Concussor case should be done with a clean lint-free cloth. DO NOT USE SOLVENTS OR
CLEANERS, as this will deteriorate the exterior appearance of the equipment.

About The Manual
This manual will explain all details about each module, along with some standard and more complex patching ex-
amples. With modular synths there are a near limitless range of patching possibilities. We can’t possibly tell you all the
different patches possible, so if you need further help and information there are many great resources on the web.
The manual is constantly being updated with new patching ideas and other information, so there will never be a final
version. Our web site has a copy of the latest manual freely available for download in PDF format.
Unlimted Customer Support
Owners of Concussor receive unlimited phone/fax/email support. We will do our best to help you get the best from
your system. If you have a lengthy or complex problem, it is probably best to call rather than email, as some things are
easier to explain than type.

Introduction
This is a lower cost alternative to the pricey alu-
minium style cases.
TheAS0084willtakeanycombinationofConcussor,
A100or Integratormodules withno problemsof gapsor
lining up because it does not use tapped strips.
Power Supply
The power supply board has 9 Doepfer style con-
nectors and 3 Integrator sockets. A 5V power rail is
provided for those modules that require it. It uses an external power suppy of 15VAC. This case uses 15V AC (NOT
DC!) Use a minimum of 500mA external power supply (not supplied). We can only supply 230V external adaptors with
either UK or Euro plugs.
As the power supply requires AC, it does not matter which way round you fit the connector. If you accidentally use
a 15V DC power supply, it will not cause any damage, but the system won’t work.
The case will generally supply a full set of modules unless there are too many power hungry modules.
Mounting
The AS0084 case eliminates the use of tapped strips, used in the metal case. This saves a heck of a lot of money,
but it does mean you must drill your own mounting holes.
The modules are mounted with self tapping screws into plastic mounting blocks. As plastic is not as strong as metal,
these cases are not ideal if you constantly are swapping modules around. Although this can be done many times, the
threadin the plastic screwholes can weakenwith time with constantscrewing and un-screwing. Ifyou do stripthe plastic
thread, you can use thread-lock, or fill the hole with glue,
All that is needed is to position modules in the case, mark the mounting holes, remove modules, drill pilot holes
approx 1mm to 2mm diameter, screw modules into position. This is far easier than it sounds, but if it puts you off then
pay the full cost for a metal case! (Nearly twice!).
Note: Integrator modules are a little wider than Concussor and A100, so it may not be possible to fill the case with
only Integrator modules - the total width may be too wide by say 0.5mm. This is because Integrator modules do not
fully stick to the Euro-rack standard. Their modules are just a tiny bit too wide, and they have positioned their mounting
holes in the incorrect place.
Note: do not overtighten the self tap screws otherwise you will strip the thread in the plastic.
If you are plugging in non-Concussor modules - you may void warranty as we cannot be responsible for
other manufacturer’s faults.
Rack Mounting
The AS0084 can be rack-mounted with optional rack-ears. The case is just a tiny bit over 3U in height.
Rubber Feet
The case come with four rubber feet. You can optionally fit these using the supplied M3 screws and nuts. It is best
to fit these if required before fitting any modules.

Handling and Inserting Modules
Modules can be placed in any position in the rack. It is a good idea to place one module in at a time and test it before
going onto the next. This way if any module causes a problem, it can quickly be identified.

Some modules contain static sensitive circuitry . This circuitry is exposed when not fitted into the rack.
Whenhandling any module,try and only handleit by thefront panel. Trynot to touchany part of thecircuitry.
It is OK to handle the edge of the circuit board. Always disconnect the rack power supply from the mains
when inserting modules or doing anything inside the rack. Note, just a few of the Concussor modules have
thepowersocket up-side-down. This should notcause any confusion as thepower cable is always supplied
fitted when buying a Concussor module.
Concussor modules feature both Doepfer and Integrator power sockets. Please state which system you
intended to use the Concussor module with so we can supply the correct power lead. Default is Doepfer.
The Concussor power supply also features sockets for both. If you run out of sockets on the power supply
board, you can purchase ‘bus power cables’ from us. These are ribbon power leads that feature multiple
power sockets - buss cables - enabling many modules to be plugged into only one power supply socket.
 It is up to you to connedt modules to PSUs correctly. Whether you have bought one of our cases, power
boards or adaptor leads, we cannot guarantee your handy work! Also we certainly won’t guarantee our modules if you
are mixing and matching manufacters. To those who have bought our adaptor cables to connect Integrator modules to
a Doepfer PSU, or vice versa:- Our adaptor cables are fully tested. However, we do not guarantee the modules or the
power supply under ANY circumstance (including faulty cable).
Please refer to the following diagrams for details of connecting the power lead to the power sockets:

Warning:
The pin outs of our sockets are the same as Doepfer and Integrator. So if you plug
them in correctly you will have no problems. Do not expect our sockets to necessarily look
the same, or be in the same oreintation as either Doepfer or Integrator. Do not assume

AS1600 6U Rackmount case
Fitting Modules
The modules are fitted into place using No.4 2.9mm diameter, 10mm long self tap screws.
When using a mounting hole for the first time, firm pressure must be applied when turning the screw for about the
first turn to tap a thread into the steel. Excessive force is not necessary, but a good fitting cross-head type screwdriver
should be used and a firm grip. Once a thread has been broken, the screw should screw in fairly easily.
If you have a module whose circuit board is really close to the edge its front panel in the far left or far right case
position, it may be necessary to place insulating tape over the nut in the side of the case (rack mount ear nut) to prevent
the module shorting out with the case. Ensure when you fit a modules on the far left or right that its PCB does not short
out on the cases. This is unlikely, but depends on the design of the module being fitted.
It is advisable to only fit one module at a time, and test each before fitting another. Always ensure the mains cable
is disconnected each time you fit a module. The problem of testing all modules at once is that if there is a problem, you
will not know which one is causing the problem.
Problems are nearly always down to the user fitting a module incorrectly.
Rack Ears
These fit to the side of the case using the screws provided. There is no need to fit these when not rack-mounting.
Power Supply
Before plugging into the mains, ensure the switch on the bottom is selected for the correct voltage of your supply.
115V (USA) or 230V (Europe).
Ensure all empty spaces in your rack are covered over with blanking panels so access into the case is not pos-
sible.

Percussion Voices
General note about all drum voices:
Trigger input:
a +5 to 12V trigger or gate signal will trigger the voice. The higher the voltage, the louder the voice will play, unless
there is a plug in the Accent socket.
Trigger with our analogue Gate sequencers, or use our MIDI to Trigger (MT16) device for MIDI control.
Accent input:
a 5-12V CV signal controls the overall loudness of the drum sound each time it is triggered.
3.5mm and 6.35mm jack sockets:
with the exception of the HH88 hihat module, all drum voices feature both sizes of jack socket on the audio output.
This enables the signal to be re-routed back to the system, or taken straight out to an external mixer or effects unit,
without the need for jack adaptors. Jack adaptors are fine, but contacts can be bad, and with 6.35mm socket to 3.5mm
plug adaptors, the extra length of the adaptor with the cable plug, combined with cable weight puts extra strain on the
module socket.

Introduction
The BD78 is an accurate replica of the CR78 bass drum sound. The module
is entirely discrete analogue circuitry, based as closely as possible on the original.
The CR78 bass drum circuitry is identical to the CR78 Bongo and Conga sounds,
so these can also be produced with the BD78.
The BD78 can produce more than just bass drum sounds...
The BD78 has the addition of a tune control. This enables the pitch
to be brought right up. This in conjunction with short decay times allows
CR78 style Bongos and Congas to be produced.
☺The BD78 can be tuned way low with long decays... watch your bass
bins mate!
Due to the way the CR78 bass drum circuitry works (using a tuned-resonance ciruit), the Tune and Decay
controls affect each other. At certain combinations of settings, the BD78 may go into self-oscillation, with loud
results! The BD78 circuitry was never designed to have manually variable Tune and Decay controls, and as we
wish to retain the original sound, this by-product has been left in and cannot be deisgned out anyway without
such a re-design it would no longer be the same drum sound. Also, you may get some small noise when you
rotate Decay pot. This is normal and not a fault with the control.

The trigger input has a range of about 5 to 12V. A trigger pulse of around 1mS is recommended, although the gate
output of a synth can be used. A larger trigger pulse will increase the level of the sound (accent the notes). When the
accent socket is used, the trigger input socket only triggers the sound and the level of the sound is controlled by the
voltage of the CV at the accent socket. The accent voltage can be from another trigger pulse generator, or from an LFO
or Envelope. When using for example an LFO, you can have the level changing with the LFO sweep.

The Tune CV input can be used to alter the tuning with any voltage. E.g. use LFO for slow pitch sweeps. Using
audio or any other high frequency signals to modulate tuning allows wild cross-modulated drum sounds to be produced.

an LFO, you can have the level changing with the LFO sweep.
The trigger LED will light each time a trigger pulse is received.

Introduction
The TM88 is an accurate replica of the TR808 tom tom drum sound. The
tune range has been extended so one module can cover low, mid and high Tom
sounds. A Noise level control has been added, so that the noise element of the
sound can be exaggerated.
Use
The trigger input has a range of about 5 to 12V. A trigger or gate signal of at
least 5V will trigger the sound. A larger trigger pulse will increase the level of the
sound(accent the notes). When theaccent socket is used,the trigger input socket
only triggers the sound and the level of the sound is controlled by the voltage of
the CV at the accent socket. The accent voltage can be from another trigger pulse
generator, or from an LFO or Envelope. When using for example an LFO, you can
have the level changing with the LFO sweep.
The trigger LED will light each time a trigger pulse is received.
Controls
Tune Sets the drum pitch. Note, the tune can be pitched down below a useful level!
Noise Changes the level of the noise. This control can sound 'scratchy'. The pot is not at fault.
