Available as an assembled Module and as a DIY project.
This Module is currently available.
Eight mono jacks with pin-strip on the backside with access to all jacks
With this module you can create a number of different functions:
For each jack you get access to the signal and a break/normalization signal. The break/normalization signal is exactly the same as the main jack signal when no plug is inserted in the jack.
All GND signals are connected to the same GND-plane.
