Connections
All connectors are located at the rear panel.
Power supply
The MAQ16/3 does not have a built-in power supply. Instead it uses a plug-in type external
power supply (DC adapter). The connector is labeled „
9V DC
“ and is located next to the two
MIDI sockets. The primary reason for this feature is the fact that line voltages and plug types
vary considerably from country to country. Using a plug-in external supply the MAQ16/3 can
be used anywhere with a locally purchased power supply, thus keeping the retail price
down.The MAQ16/3 is switched ON by plugging the AC adapter into a wall outlet and
connecting it to the appropriate jack on the back of the case. There is no separate ON/OFF
switch.
MAQ16/3 sequencers sold in Germany do include an AC adapter for 230V mains supply.
In other countries the power supply is NOT included with the MAQ16/3 and must be
purchased locally by the user. The power supply must be able to deliver a voltage of 9-12
VDC (unstabilized), as well as a minimum current of 500mA. The polarity of the connector
must be the following: ring = GND, tip = +9V DC. If the polarity of the power supply is
incorrect, the MAQ16/3 will not function. However, there is no danger of damage to the
circuitry since it is protected by a diode.
MIDI-Connectors
Next to the power supply connector you will find the two MIDI connectors „MIDI-In“ and
„MIDI-Out“.
Connect the MIDI-OUT jack of the MAQ16/3 with MIDI-IN of the device to be controlled
(Expander, Synthesizer, etc.) via a suitable MIDI-cable.
The MIDI-IN jack of the MAQ is needed only if the device is to be synchronized via MIDI-IN,
if sequences of notes are to be transposed or if the MIDI remote control features are used.
Otherwise the MIDI-IN jack remains unused. It should be emphasized that the MIDI-IN jack
has no merge-function, i.e. incoming data is not passed on to the MIDI-output.
If the MIDI data controlling the MAQ are required for other MIDI equipment too a MIDI Thru
box has to be used.
If the MIDI data coming from the MAQ should be merged with other MIDI data a MIDI merge
boxed has to be used (e.g. the Doepfer MMR4/4 with 4 MIDI-Ins and 4 MIDI-Outs).
