Powered up the SE beast on my desk and did some measuring today.

Mic BIAS is always active.
At high impendance BIAS is 1.74v wich works really good.
At low impendance BIAS is 1.9v and sound crap. Almost no sound at all.

I'm gonna update my schematic with some more measured voltages and minor corrections. Someone clever enough could probably calculate resistor values from this.
