FRONT PANEL
Attach the
front panel
adjusting the parts one by one if necessary until it fits. At this point a pair of fine tweezers can be
helpful.
To Finish:
- Screw in the parts in this order: A)
Mini-jacks
B)
Pots.
- Ensuring all of the above parts are flush with the panel and both PCB and panel are perfectly parallel. Then
you can
finally solder
them!
- Fit the LEDs on the panel holes and solder them
- Put the
knobs
on the potentiometers and the red caps on the switches/Faders.
- Connect the
power ribbon cable
: The red wire (-12V) on the power ribbon cable corresponds to pin number one
on the male power connector. The number one pin is indicated with a small triangle on the male power connector and a
white line on the main PCB. A white or black line (or “-12v”) marked on your power bus normally indicates the
corresponding pin.
