5. Jumper Settings
You may customise your A-190-4 to your needs by
removing / changing positions of some jumpers on the
backside of the module’s circuit board. You will find a total
of seven jumpers, but only three of them are of
importance.
JP2 (CV-bus) and JP3 (gate bus):
If you want to run more than one A-190-4 with just a
single system bus, only one of the A-190-4’s must be
connected to the system bus.
Disconnect the other A-190-4 modules from the system
bus by disconnecting the two jumpers labelled JP2 (CV
bus) and JP3 (gate bus). Both jumpers are located on the
backside of the A-190-4 circuit board. Please refer to
page 5.
JP4 (gate level):
Some vintage synthesizers require a gate level of 10V or
more. In case you want to control such an instrument with
the A-190-4 you may alter the gate level from +5V
(default) to +12V. You can do this by changing the jumper
JP4’s position on the backside of the A-190-4 module.
The lower position provides +5V, the upper position
+12V. Please refer to page 12, 13 chapter 4.3.2 ”Trigger
menue“.
Please leave all other Jumpers untouched !!!
Otherwise serious malfunction will occur.
