4 Connection
All connectors described here are located at the back of the
device.
4.1. Power supply
4.1.1. Version with external
transformer
•
For the export market, the Schaltwerk is to be used
with an external power adaptor as it doesn’t
incorporate its own integrated mains supply. The
connection for the adaptor is indicated “9V DC” and is
located to the right of the 5 DIN connectors (MIDI &
Sync).
•
On request, we may deliver a 115V external
transformer with “euro” type mains plug. Other mains
voltages require that you purchase the appropriate
adaptor in your own country. Only adaptors with a
VDE or equivalent technical agreement are
recommended. The output voltage should be around 9
Volts (ranging from 7 to 12 V.), unregulated DC, with
a minimal output current of 500 mA (0.5 Amps). The
polarity of the output plug should be: external ring =
ground, inner ring = +7..12V. If the polarity is
inadvertently inverted, the Schaltwerk will not function
but won’t be damaged as there is a built-in protection
diode.
•
The Schaltwerk is functional as soon as the adaptor is
plugged into the mains outlet, and the low voltage plug
is inserted at the back of the machine. There is no
supply switch provided.
4.1.2 Version with built-in 230V.
mains supply
•
The Schaltwerk will enter in function as soon as the
mains connector is hooked up at the rear of the
machine, the mains plug is inserted in the outlet, and
the mains switch is set to ON.
4.2. MIDI connection
4.2.1. MIDI-IN connection
•
The MIDI inputs 1 and 2 are dedicated to the control
and synchronization of the Schaltwerk by external
MIDI real-time messages, remote control of specific
functions and effects trough MIDI (effect menu, etc.)
and reception of MIDI Sys-Ex Dumps.
•
The MIDI inputs have no merge capability, i.e., The
incoming MIDI information is not retransmitted to
any of the MIDI outputs. If the data directed at the
Schaltwerk should also be available to other MIDI
devices, it is advised to use a MIDI-Thru-Box with
several outputs. Should this MIDI data be merged
with other MIDI information to jointly drive the same
device, then an external MIDI-Merger is needed:

4.2.2. MIDI-OUT connection
•
The MIDI output 1 is dedicated to the Schaltwerk
generated MIDI information and to the Schaltwerk
issued MIDI-Real-time messages.
•
To date, the MIDI output 2 is restricted to the
transmission of Schaltwerk issued MIDI-Real-time
messages.
4.2.3. MIDI in-out connection
•
MIDI IN 1 and MIDI OUT 1 are thought as the main
link with the outside world.
•
In future software versions, MIDI IN 2 and MIDI
OUT 2 are planned to be part of a communication
network between various machines.
