Overview
Sys mixer is an open-source printed circuit board by ASzc, from the ASzc/sys-mixer repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 122 × 84 mm with 16 parts on 13 nets, routed with 83 tracks and 0 vias.
Its parts include 4 resistors, 3 connectors and 1 switch. It belongs with the audio and music boards of this library.
README
README.mdSYS Mixer
The SYS Mixer is a conversion board for the SYS from Schitt Audio. It turns it into a passive line-level audio mixer, rather than switching between the inputs in a binary manner.
The pushbutton switch selects which channel the variable resistor attenuates. Only one channel can be attenuated at one time, due the limitations of the SYS's default control layout.

Questions
How big is the Sys mixer PCB?
It measures 122 × 84 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sys mixer use?
16 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Sys mixer KiCad files?
From the ASzc/sys-mixer repository on GitHub, at the commit this page was made from: the board is sys-mixer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sys mixer design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
