PREFACE
First of all, congratulations on the purchase of this 3U Eurorack synthesizer
mo ule. This manual contains a con ense escription of the functionality
an a resses users with a certain level of elementary technical knowle ge.
The CS-8 DST2 is a very effective an very low noise istortion base on the
principle of ban saturation. It is working as a 2-ban - istortion, where the
input signal will be spectral separate via a crossover network at a crossover
frequency of 113 Hz fee ing afterwar s the respective istortion stages. By
this a more etaile result can be obtaine without loss of warmth. It is
esigne for mounting into a 3U Eurorack with an internal +/- 12V power
supply.
The technical principle is borrowe our well-known pro uct "ebbe un flut"
an highly improve in respect of inherent noise by substitution of electronic
components.
Design an implementation meet highest technical stan ar s concerning
usability, soun quality, an signal-to-noise ratio. The front panel is ma e from
pow ere an printe piece of aluminium sheet metal of 2 mm gauge. The
entire esign an pro uction work was one in Germany.

1. Inpu Controller – attenuates the incoming au io signal at
jack 3
between 0 an 1
2. Drive Controller – rives the input signal at jack 3 into the saturation or
har clipping, resp. from 1% to 100%
3. Inpu jack (input) – routes the applie signal via Cont. 1 to the istortion
input
4. Ou jack (output) – provi es the istortion output signal

7.3 Ini ial opera ion
The power connector’s (1) pin-out in top view (refer to fig. 2) is assigne as
follows:
Bottom to top, left to right. Thus pin 1 is locate at bottom left, pin 2 above pin
1 etc. Pin 15 is at bottom right, pin 16 at top right.
Pin 1, 2 = -12 V (labelle with a triangle)
Pin 3-8 = GND (groun , 0 V), locate outwar on all jacks
Pin 9, 10 = +12 V
Pin 11-16 = not in use
To hook up power to the mo ule, connect one of the IDC-jacks of the inclu e
flat ribbon cable to the connector (refer to fig. 2). Observe gui e key for the
polarity of the connector in or er to avoi pin reversal. The red ag of the
cable is o ma ch he riangle-label.

Fig. 3 Structure of DST2
Fig. 3 shows the structure of the istortion unit. The input signal will be
spectral separate by a high-/low-pass crossover network at 113 Hz before

Inpu
This section inclu es the jack 3 (Input) an the controller 1 (Input). The input
signal to be processe by the DST2 flows from
jack 3, capacitively ecouple ,
to the Cont. 1 where it is attenuate between 0 (-∞ b) an 1 (0 b). 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 inclu es the controller 2 (Drive) an the jack 4 (Out). With rising
movement from left to right of Drive in irection to 100% on the scale the
input signal will be riven more an more into saturation. With input signals of
about 4 Vpp or larger a secon kin of istortion starts at position 3 o'clock of
Drive, which a s some more "sweet" harmonics to the result at jack 4 (Out).
Hint: This dis or ion is always working, so at Drive at 1%, too! If a totally
clear signal is wishe , the DST2 shoul be remove from the signal path.
Fig. 4. shows the transfer function of a istortion stage for rising Drive-
positions (left to right). Let be the momentary input voltage values on the
horizontal axis an the respective output value on the vertical one.
