Master Module: Jack Multiple and Attenuator Option
Fit twelve Switchcraft sockets into the spaces on the Master Panel. Align them so that the
bevel faces to the top right as you look at the back of the unit. With a single piece of 20SWG
tinned solid core wire connect all the ground lugs together on the right hand column. Now do
the same on the left hand column. Solder another piece of solid core wire across the two
vertical pieces so that it connects both columns together. Make this 'bridge' just below the top
eight sockets, that is, between the fourth and fifth socket down. Now with insulated wire
connect this wire frame back to the dedicated 0V screw terminal on the PSU board.
Now connect all the signal lugs, marked as T on the body of the socket, on the first four of the
right hand column of sockets. Then do the same on the left hand row.
You should now have four vertical wires, two running down the top four sockets, and two
running down over six. Your multiples are now complete.
The KEY CV and GATE sockets now need to be connected to the Oakley Dizzy buss. Use a
three way 0.1” Molex or MTA100, as described in the Dizzy User Guide, to connect the
signal lugs on these two sockets to the CV and Gate buss.
The 10:1 attenuator is simply made. Connect the signal lug on the right hand socket (IN) to
the signal lug of the left hand socket (OUT) with a 47K resistor. Then solder a 4K7 resistor
from the signal lug of the left hand socket to the ground lug of the same socket. And that's it!
