dimensions, which affects the feel of the unit. Because of this, no fixative
has been applied to the three machine screws that hold the assembly to the
panel. The feel can be adjusted by tightening or loosening these screws with
a T6 Torx © or equivalent Star-drive driver. In case a screw should become
lost, they are M2x0.40 7mm button-head machine screws.
Controls, I/O
X: Horizontal axis, left or right motion output
Y: Vertical axis, up or down motion output.
Scale: Controls the scaling/gain of the signal. Middle position is
unity gain/1:1 scaling, counter-clockwise attenuates, clockwise amplifies.
Offset: Controls the offset or bias of the signal. Used to shift the
output up or down.
Ref: Reference level for input. Put switch lever in direction of the
wavy line if using an AC input signal, or toward the flat line for a DC
signal.
In: Input signal goes here. When a plug is inserted, the unit
automatically switched from internal DC source to the input signal.
Out: It's the output, where the new signal comes out.
T: Trigger output.
G: Gate output.
T/G: Pushbutton to initiate Trigger and Gate signals.

Figure 1 shows the rear
of the PCB. The trim pots shown
control the default amount of
bias or offset of the output.
During testing, the unit
is adjusted for minimal bias
with an AC input signal. This
will not satisfy all situations of
course, so you may adjust the
bias to suit your needs.
