Power Supply

d3m
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
(mains) out of the
d3m
increases the electrical safety. Another reason for the external power
supply is the fact that line voltages and plug types vary considerably from country to country.
Using a plug-in external supply the
d3m
can be used anywhere with a locally purchased
power supply, thus keeping the retail price down.
In Europe a VDE approved power supply is included with the
d3m
. In other countries a
power supply with suitable mains voltage and mains connector has to be purchased
separately by the user provided that the dealer resp. representative does not enclose the
power suppy. The power supply must be able to deliver 7-13 VDC unstabilized or stabilized
voltage, as well as a minimum current of 100 mA. The correct polarity of the DC voltage
connector is: outside ring = GND, inside lead = +7...13V. An external power supply of high
quality and safety should be used. If more than one
d3m
has to be powered by one power
supply the minimum current has to be a multiple of 100 mA (e.g. 200 mA for two
d3m
, 300
mA for three
d3m
).
Remark: The value "250mA" printed on the rear panel is no longer required. For the new
series of d3m a current of 100 mA is sufficient (but a 250 mA supply would be fine also)!
The
d3m
has two power supply sockets available that are internally connected. In case that
two or more
d3m
are operated only one power supply is required. The power supply is
connected to one of the
d3m
. The second
d3m
is connected to the second supply socket of
the first
d3m
via a special DC cable that is equipped with a DC plug on each side.
The
d3m
is switched on by plugging the AC adapter into a wall outlet and connecting it to the
appropriate jack of the
d3m
. There is no separate on/off switch. If the polarity of the power
supply is incorrect, the
d3m
will not function. However, there is no danger of damage to the
circuitry since it is protected by a diode.
MIDI OUT
o
/ MIDI IN
p
This is the Midi output resp. input of the
d3m
. The connection of these sockets depends
upon the type of operation:
•
Only
one
d3m
is in use: In this case the Midi Out socket of d3m is connected to the Midi
In socket of the device to be controlled by the d3m (e.g. a computer that runs Native
Instruments' B4 or Emagic's evb3, or an organ sound generator) via a suitable Midi
cable. The Midi input of the
d3m
remains unconnected in this case.
