Setonix Synth Marsupial - DIY Build
Following up our last build of the Setonix Synth Boing!, we decided it was time for another back to back build of their Setonix Synth’s newest module, Marsupial. What is it you ask?
The Marsupial is a dual VCF module that is based around the re-issued AS3350 filter IC. Due to its normalization between the control inputs and the parallel switch, the Setonix Synth Marsupial is a unique filter that can surprise any artist when patching it up. With that being said, let’s jump into the build.
Let's Get This Build Going..
Starting off with the build of this module, we will work on the backside of the PCB first. You will want to solder the 2×5-pin power header, 3-pin Series selection header, and two 25k multi-turn trimmers.
Be careful not to hold the iron on the parts for that long as you can release or damage some of the pre-soldered SMD components.
Don’t forget to place the plastic shunt over two of the three pins of the 3-pin header–”BP” will normalize Filter A’s Bandpass output to the Series switch, while “LP” will normalize Filter A’s Lowpass output to the same.
