Make an A/B switch out of the SCHLEUßIG
This is a expander module for the LPZW.modules SCHLEUßIG
It adds 8 extra inputs (one per channel) which get routed to the output when the original channel input is muted. Thus making the SCHLEUßIG an A/B switch.
It is passive and connects internally to the alt-in connector of the SCHLEUßIG.
These merchants probably sell this module. Huh?
