MM2196 panel

All about it

An obscure-but-fun module!

This module is a happy byproduct of my need to demonstrate a "proof of concept" of the Corlette module at SuperBooth 2019 before the phase splitter circuit was ready. Enter a quickly designed but easy to build rendition of a classic 1960s discrete circuit. 

What this does is take an audio signal (above 1.7Hz) and output two signals, with the harmonics in each signal pushed either 45 degrees forward or backwards. This gives you a quadrature signal, ideal for driving our Boethian Wheel, or experimenting with driving vector displays such as lasers or oscilloscopes.

Just as interestingly, it works to distort the wave shape of harmonically rich sounds-allowing even square waves to become fodder for wavefolding.

To increase the functional density over the original, two individual units are stacked on top of each other behind the panel.

Tech Notes

This is a very easy DIY build, with limited panel wiring, and an open jack field to allow wiring with the circuit boards attached. To split the difference with design enhancements in its 200-series equivalent, we have used modern high-gain transistors but otherwise the circuit is untouched. You will need a dual-trace oscilloscope to make final calibrations.
