PM4x4: 4x4 passive matrix mixer (14HP, prebuilt)

A re-release of one of my older modules - a 4x4 passive matrix mixer.

For those not in the know, a matrix mixer is a device that routes multiple input signals to multiple output destinations. It allows for flexible and complex routing of signals, enabling users to create custom mixes and effects chains.

Unlike a traditional mixer, which typically combines inputs into a single output, a matrix mixer provides individual control over the routing and mixing of each input to each output.

TL;DR - you can do funky mixing effects with it.

Note that as this is a passive mixer, meaning that you won't be able to generate feedback and other squally effects using the module on its own (you'd need some external amplification for that) but it's still good for taking up to four sources, mashing them together and then sending them to up to four different destinations.

Inputs are capacitively coupled (ie. any DC offset in the signals will be removed) 

This is a pre-built version of the PCB/panel set - I'm only making a couple of these available so get 'em while you can; PCB sets will continue to be available. Unlike most of my other modules, this one is fitted with light grey micro-knobs - you're prefectly at liberty to change them for something else if you see fit, though (you'll need knobs with T-18 shafts)
