Hi,
lost almost a whole day of troubleshooting today, due to a broken Channel Extender

Swapped cards on the channel, took out the Patchbay, checked the wiring til the Connectors at the Backplate.
Then traced the signal on the extender Pins, they were broken. Mic In hot/cold.
I was trying to find a fault at a Micpre...
There is another Part of the Channel extender were someone already soldered something.
Could someone please confirm that Pin 78 is not connected to anything and ends below the blue Edge connector?
I am not sure if it was soldered to Pin 77...
Damn,
thank you!
