Wrong symbols on PCB?

oh damn i think i know why. these pins have no contact with the pcb whatsoever.

Maybe, possibly, probably. There are a whole lot of different XLR connector footprints for slightly different models and also for different brands. Connectors are by far the most troublesome footprint type because there are so many variations.

[tutorial] Test fitting Footprints

A small demo to show how I test fit footprints. It’s a combination of a few things to make it work perfectly. The first step is to print a PCB mirrored on a piece of Paper: PcbNew → File → Print → Options Mirror → Print. 2nd step: Take a needle and pre-punch all the mounting holes into the paper. (For the large holes I used a hole punch). 3rd step: Carefully put the connector into the sheet of paper. 4th step: Take a picture or scan the whole contraption with a flatbed scanner. This make…

It’s not about track width but clearances, they are shown my the outline around pads . . .

0.2mm in Board constraints and Default Netclass

now 0.1mm in Board constraints and Default Netclass

0.25mm clearance means this device cannot be routed too as it has no clearance

which number should i change?

[DevFelix]

Btw. i can connect something to the preamp, just not to the xlr combo jack.

I guess that you don’t have a connecting Net then . . .

[DevFelix]

Im pretty sure its connected

The little squares and circles indicate open ends. ERC will also flag this. Have you run ERC?

Global labels for “inputs” and “outputs” have their attachment points on “opposite” sides. When in doubt, you can simply drag a label to the side. When there is a connection to the pin, then KiCad will draw the connecting wire in between.
