Please note:
•
The main DSG pcb is the same as used for other incarnations of the DSG mk2 - whether the
DSG pcb is a “contemporary version” or a “classic” version does not matter. However,
both
sides have to be set (adjusted) for common CV control
:
•
There
must be a link or zero-ohm resistor
at the 2 spots marked “
COM
”; and
•
The 4 spots marked “
SEP
”
have to be empty
(remove any zero-ohm resistors).
•
Connect only the pins within the white rectangular boxes
marked on the panel pcb.
Ignore the ones marked blue in the picture above
.
•
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, pin stripes to connect the main pcb to the com-
ponent pcb, MTA power header - the second (smaller) power header is for convenience, you can
use it to power another module next to the DSG.
•
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 LED
s - at least 100-130mcd or ultrabright
LEDs (60°) plus a
trimpot of (only) 2k or (or a 2k resistor) for (fairly) bright LEDs (
100-
150mcd). If you use ultra-bright LEDs, a 5k or higher trimmer might be needed.
•
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.
