05. OPTION 3: LINKING PARTS

This option enables you to link the four parts (or specific 
parts) together. Meaning that the first jack of each part 
will be normalized to the previous part, so if you don’t 
connect anything to the first jack, the 3 outputs of that 
part will output the input of the previous part. This al-
lows you to split a single signal to 12 outputs maximum.

This is an available addition to both the passive and the 
buffered options.

00.  Orient the PCB as seen on the left.

01.  Bridge the solder jumpers

Part 1 -> Part 2

Part 2 -> Part 3
