Hi Kemper Rack user,
I had enough of fumbling with my fingers inside the rack case to plug in or unplug the connectors.
Also, I was somewhat worried about the durability of USB and RJ45 ports...
So I used the very warm weather here in Germany and disappeared into the cool basement...
Material:
2x Neutrik NC3 MD-LX-B
2x Neutrik NJ3 FP-6-C-BAG
1x Neutrik NE8 FDP
2x Amphenol ACPM-GN Mono
1X USB connector
IEC Socket with switch
Also 2 XLR female plug I had
A fiew piece of cable
Cost was roundabout €45.- and a few hours fun
