Florian,

the XLR is used for the 16V AC coming from the encapsulated transformer of
the DIY kit. So it's OK. We pay attention that no dangerous voltages are
accessible  in the DIY kits. That's also why the standard PSU is not used in
the DIY kits. The PSU board you can see in the pics looks a bit like the
standard PSU but it's the DIY PSU and does not include the transformer but a
16V AC input instead of the transformer.

Anyway - thank you for your alertness. In any case electrical safety is
essential !

Best wishes
