MIDEX-8
English – 38
Selecting a Power Supply
If your USB hub doesn’t provide the necessary power for the MIDEX-8
or if you wish to play the sound modules in your MIDI system from your
master keyboard with the computer off and without having to change
cables, you need an additional power supply for your MIDEX-8.
To make things easier for you, we have defined the additional MIDEX-8
power supply requirements in such a way that almost any power sup-
ply unit available can be used. This can either be a DC or an AC device,
and you don’t have to consider polarity. The only definite requirement
is a power output of at least 500 mA (milliAmpere)!
Please note the following:
❐
The power supply voltage should at least be 6 volts and must not exceed
12 volts!
❐
The MIDEX-8 socket has been designed for a “low voltage plug” (outer
diameter 5.5 mm, inner diameter 2.1 mm).
❐
Please note that “low voltage plugs” are also available with an inner diam-
eter of 2.5 mm. These can also be used in connection with the MIDEX-8,
but the plug will easily fall out of the socket. We therefore recommend that
you do not use plugs with this inner diameter.
