RANDOM*SOURCE
2
Serge SSG
Random Source and SSG essentially use the same main pcb, however, the SSG version only contains parts in
the upper area whils the RS requires the fully installed pcb (i.e. also the lower area containing the Serge Noise
Source and Sample&Hold).
Please note:
•
The Random*Source SSG pcb is available in different configurations -
for the “normal” SSG,
the pcb version that only contains the upper parts is sufficient
(i.e. not the ones greyed-
out in the picture above).
•
Orientation of the main pcb:
power header is at the bottom
(when looking at the module up-
right, e.g. in a rack).
•
Use antistatic precaution
when handling the pcb - don’t touch the small SMD parts and ICs
with your hands.
•
Only these parts have to be soldered in: trimpots, 220nF Film capacitor, pin stripes to connect the
main pcb to the component pcb, MTA power header (see picture above).
•
LED: To set / control LED brightness, install either trimpots (“LED”) or resistors (e.g. 2k) on the
component pcb - do not install both!
Use low current (max 2mA) LED
s - resistor on board),
when using blue or white this is less relevant.
•
The component pcb contains some potentiometer footprints that allow you to chose the direction
in which the potentiometer works. Use the “NORMAL” orientation (as marked on the pcb) unless
you have a good reason not to.
