Synton 3022 Binary Divider Module

The 3022 is a simple binary divider for audio or control voltages

 

This description comes from the Series 3000 Modular Synthesizer Instructions Manual.

 

 

The PCB is mounted to the panel with the banana jacks. I had removed the PCB as part of the modification so the jacks have been added in this photo.

 

 

I have added wires to the PCB for the upgrade to 3.5mm jacks.

 

Operation

Operation is straightforward. The input is biased a bit positive and the threshold appears to be around 400 mV or so. A 500 mV unipolar signal was high enough amplitude for reliable triggering.

 

 

3.5mm Modification

I converted this module to 3.5mm jacks. Since banana jacks aren't normalled, I didn't normal the input jack. I made a bracket to mount the PCB by the banana jack holes and the bracket thickness precluded the customary washer under the right two jacks. I used Switchcraft 35PM1 3.5mm  jacks.

 

I made this bracket to mount the PCB.
