Connection and Installation
Please pay attention to the following notes !
Electronic basic knowledge is required to install the WE electronics and to connect the controls.
If you are not sure whether your knowledge is sufficient please consult an expert. We cannot
take back modules that became defective because of wrong installation or wrong connection of
the controls or voltages. We also cannot take back modules or cables which have been
soldered by the user.
Power Supply (1)
WE does not have a built-in power supply. Instead it uses a plug-in type external power supply
(AC adapter). One reason for this feature is electrical safety. Keeping danger voltages (main)
out of the WE increases the electrical safety. Therefore an external power supply of high quality
and safety should be used. If WE is used in Germany the external power supply has to be VDE
approved. Another reason for the external power supply is the fact that mains voltages and plug
types vary considerably from country to country. Using a plug-in external supply WE can be
used any where with a locally purchased power supply, thus keeping the retail price down.
The power supply has to be able to deliver 7-12 VDC unstabilized voltage, as well as a
minimum current of 100mA. WE is switched ON by plugging the AC adapter into a wall outlet
and connecting it to the appropriate jack on the WE board. There is no separate ON/OFF
switch. After power on the preset adressed by the setting of the jumpers is called up.
If the polarity of the power supply is incorrect, WE will not function. However, there is no danger
of damage to the circuitry since it is protected by a diode. The correct polarity is: outside ring =
GND, inside lead = +7...12V. A power supply for 230V mains voltage with European type mains
plug is included with the WE (valid only within Europe, for other countries ask you local Doepfer
representative or dealer).
Midi Out Socket (2)
Connect the Midi Out socket with Midi In of the device to be controlled by WE (e.g. sound
expander, synthesizer, sample player, computer with Midi interface and suitable software,
second daisy-chained WE) via a suitable Midi cable. If you want to control more than one Midi
device you have to use daisy chain Midi Thru / Midi In connection of the devices ore use a
external Midi Thru box.
