It works perfect direct Mic IN with Plugin Power 2.845 Volt, the internal resistor from the D 50 is ok.
Max Currentlimit for DPA 40XX is 1mA. Voltage is a bit low but works. Mikamp Noise is ok for louder sources.
Long time ago I made an adapter out of an Microdot Extension cable cutting thru.
Microdot / XLR and from connected ( my Mictrotrack used) XLR cable to 3.5 Minijack Stereo.
Will solder it again, now direct Microdot /Mini Jack .
