OPERATING AND SAFETY INSTRUCTIONS
Please follow the given instructions for use of the instrument because this will
guarantee correct instrument operation. Due to the fact that these instructions touch
on Product Liability, it is absolutely imperative that they be read carefully. Any claim
for defect will be rejected if one or more of the items was observed. Disregard of the
instructions can endanger warranty.
•
The instrument may only be used for the purpose described in this operating
manual. Due to safety reasons, the instrument must never be used for other
purposes not described in this manual. If you are not sure about the intended
purpose of the instrument please contact an expert.
•
The instrument has to be shipped only in the original packaging. Any instruments
shipped to us for return, exchange, warranty repair, update or examination must
be in their original packaging! Any other deliveries will be rejected. Therefore, you
should keep the original packaging and the technical documentation.
•
The instrument may only be operated with the voltage written on the power input
on the rear panel. Before opening the case disconnect the power plug.
•
Every modification has to be carried out only at the manufacturer or an authorized
service company. Any modification not released by the manufacturer leads to the
extinction of the operation permission.
•
With the introduction of a third person the warranty will be lost. In case of a
destroyed warranty seal, any warranty claim will be rejected.
•
The instrument must never be operated outdoors but only in dry, closed rooms.
Never use the instrument in a humid or wet environment nor near inflammables.
•
No liquids or conducting materials must get into the instrument. If this should
happen the instrument must be disconnected from power immediately and be
examined, cleaned and eventually be repaired by a qualified person.
•
Never subject the instrument to temperatures above +50°C or below -10°C.
Before operation the instrument should have a temperature of at least 10°C. Do
not place the instrument into direct sun light. Do not install the instrument near
heat sources.
•
Keep the top side of the instrument free in order to guarantee proper ventilation,
otherwise the instrument could be overheated. Never place heavy objects on the
instrument.
•
All cables connected with the instrument must be checked periodically. If there is
any damage the cables must be repaired or replaced by an authorized person.
•
Transport the instrument carefully, never let it fall or overturn. Make sure that
during transport and in use the instrument has a proper stand and does not fall,
slip or turn over because persons could be injured.
•
Never use the instrument in the immediate proximity of interfering electronic
devices (e.g. monitors, computers) since this could create disturbances within the
instrument and corrupt memory data.
•
The exchange of electronic parts (e.g. EPROMs for software update) is allowed
only if the instrument is disconnected from power supply.
•
When using the instrument in Germany, the appropriate VDE standards must be
followed. The following standards are of special importance: DIN VDE 0100 (Teil
300/11.85, Teil 410/11.83, Teil 481/10.87), DIN VDE 0532 (Teil 1/03.82), DIN
VDE 0550 (Teil 1/12.69), DIN VDE 0551 (05.72), DIN VDE 0551e (06.75), DIN
VDE 0700 (Teil 1/02.81, Teil 207/10.82), DIN VDE 0711 (Teil 500/10.89), DIN
VDE 0860 (05.89), DIN VDE 0869 (01.85). VDE papers can be obtained from the
VDE-Verlag GmbH, Berlin.
Introduction
The A-100CGK is a monophonic keyboard with CV and Gate outputs. The main
application is the control of an A-100 system but even other modular systems or
synthesizers can be controlled provided that they use the 1V/octave standard. In
addition the A-100CGK has a Midi output.
The A-100CGK is a available as a ready built device with black metal case and a four
octave keyboard or as an OEM module. The OEM module contains only the
electronics kit and can be combined with any Fatar keybed with 2, 3, 4 or 5 octaves
(e.g. TP/6, TP/60, TP/7, TP/8S, TP/8O, TP/9). For these versions we do not offer a
suitable case. Rather the case has to be built by the customer. It's also possible to
install the OEM version with a suitable keybed (max. 4 octaves) into the top cover of
the A-100 Monster Base. Some of the available Fatar keybeds are listed on the
accessory page on our website www.doepfer.com > products > accessories. The
complete overview of all keybeds can be found on the Fatar website www.fatar.com.
All Fatar keybeds with up to 5 octaves can be combined with the A-100CGK OEM kit
(longer keybed are not possible).
These are the most important features of the A-100CGK (ready built version):
•
slightly weighted four octaves keybed TP/9 with velocity and monophonic after-
touch
•
black aluminium case with white printing
• available in/outputs:
o
CV1: controlled by the currently pressed key, 1V/octave standard, 0...+5V
range (5 octaves)
o
CV2: controlled by the velocity, 0...+5V range
o CV3: controlled by the after-touch sensor, ~ 0...+2.5V range
o Gate: 0/+5V (can be changed internally to 0/+U or S-Trig, +U = voltage of the
used power supply, as for this modification the case has to be openden it
should be carried out by a specalized service center)
o Midi In (so far not used)
o Midi Out (only channel 1, with velocity, 0V CV1 corresponds to Midi note
number 36)
o 9V DC (for supply with an external wall outlet adapter, 7...12V are possible)
o 9 pin sub-D connector with CV1, CV2, CV3, Gate, Midi Out and supply voltage
(to establish a connection to the A-100 with one cable only and power the A100CGK from the A-100 frame, a suitable adapter module is in the planning
stage)
• available menus/buttons with LEDs
o Mode: selects the key for CV1 when more than one key is operated ar the
same time
lowest key priority
highest key priority
last key priority
o Transpose, 2 different transpose modes can be selected in the configuration
menu
0/+1 octave or
0...+12 semitones
o
Retrigger: this parameter controls the Gate behaviour while legato play (i.e.
when a key is operated while another one is already pressed), 0 means that the
Gate is not reset in this case, 1...20 defines different reset times in
milliseconds. This is necessary from our experience as some ADSR generators
require a longer reset time to be retriggered. For the A-100 envelope
generators (e.g. A-140) setting "1" is OK, i.e. shortest reset time is sufficient.
For other envelope generators the minimum reset time has to be tried out.
o Hold: If this key is operated the Gate is held even if the key is released
o
Up/Down: buttons to increase/decrease the value of the currently selected
menu. In addition the value of the selected parameter can be increased by
operating the corresponding menu button again.
• additional basic parameters are adjusted in a special configuration mode and
include parameters that are normally fixed, i.e. they are not changed during the
play. The configuration mode is selected if the up or down button is held down
during power on:
o
keybed type (2/3/4/5 octaves, necessary for transpose and offset options, has
to be set to "4" for the ready built version)
o transpose mode (0/+1 octave or 0...+12 semitones)
o Gate polarity (useful if an inverted Gate behaviour is required, e.g. for Moog
synthesizers or systems)
•
An external power supply (7-12VDC@min. 250mA) is used. Within Europa the
wall outlet power supply adapter for 230V mains voltage and European type
mains plug is included with the A-100CGK. In other countries the power supply
has to be purchased by the user in his country. If there is a Doepfer
representative in your country (see dealer link on our website) please ask the
representative if the power supply is included in your country.
•
four 80 cm A-100 patch cables are included to connect the four outputs of the A100CGK to the A-100 system. If your system uses 1/4" jack sockets special
cables (3.5 mm to 1/4" jack plug) have to be ordered separately. These cables
can be found in the accessories section of the price list on our website.
•
As soon as the A-100CGK adapter module is available the keyboard can be
powered from the A-100 system. In this case no external power supply adapter is
necessary. The adapter module is in the planning stage.
•
Dimensions: ~ 790 length x 200 depth x 65 height, measures in mm (ready built
version with octaves keybed and metal case)
•
weight: ~ 4.5 kg (ready built version with octaves keybed and metal case)
