Connections (rear panel)

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

/ MIDI IN

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.
