Input
This section includes the
jack 3 (Input)
and the
controller 1 (Input)
. The input
signal to be processed by the DST2 flows from
jack 3,
capacitively decoupled,
to the
Cont. 1
where it is attenuated between 0 (-
∞
db) and 1 (0 db). To obtain
a signal gain of 1 (input to output, "Drive" at full CCW) at the signal output
Out
Cont. 1 has to be set to full CW.
Drive
This section includes the
controller 2
(
Drive
) and the
jack 4
(
Out
) . With rising
movement from left to right of
Drive
in direction to 100% on the scale the
input signal will be driven more and more into saturation. With input signals of
about 4 Vpp or larger a second kind of distortion starts at position 3 o'clock of
Drive
, which adds some more "sweet" harmonics to the result at
jack 4
(
Out
) .
Hint:
This distortion is always working , so at
Drive
at 1%, too! If a totally
clear signal is wished, the DST2 should be removed from the signal path.

positions (left to right). Let be the momentary input voltage values on the
horizontal axis and the respective output value on the vertical one.
