D Sound module USM-RC-2

Connection of the loudspeaker:
You can connect 1 or 2 loudspeakers to the USM-RC-2. The first loudspeaker is
connected to terminal X5. The second loudspeaker can be connected optionally to
terminal X6.
The red wire of the loudspeaker connection cable is connected to the positive pole of
the loudspeaker. The black wire of the loudspeaker connection cable is connected to
the negative pole of the loudspeaker.
You are not allowed to connect the loudspeaker outputs to each other! So do
not try to connect both loudspeaker outputs to 1 loudspeaker!
The supplied loudspeaker connection cables should not be extended to prevent
interference of the receiver (especially by FM systems)! The loudspeaker connection
cables should be installed far away from the receiver and the antenna.
Connection of the switching-outputs:
The outputs 1 to 10 of the module are located at the pin connector X3. The outputs
11 and 12 are located at X1/9 and X1/10.
For outputs 1 to 10 it is recommended to use the supplied ribbon cable, which is easy
to mount on the pin connector. Of course other cables/plugs can be connected to X3.
The sound module is always switching the negative pole to each output and thus to
the connected load. The positive pole is always connected permanently to the load
(see wiring diagram).
The common positive pole for all outputs is located at X1/8. But you can also connect
for example the load directly to the positive pole of the battery.
Ribbon cable assignment:
Output Ribbon cable
1 brown
2 red
3 orange
4 yellow
5 green
6 blue
7 violet
8 grey
9 white
10 black
In order to receive the right cable colors, the ribbon cable must be put on correctly to
the connector. Theoretically it could be put on rotated by 180°; however, the
configuration would be changed in this case. To put the cable on correctly the brown
wire must face upwards (board middle), the black wire downwards (board edge).
