Looking forward to the anechoic chamber test results.
2xEM172 -> D50 Mic Input
2xEM172 -> TelingaPre low gain -> D50 Mic Input
2xEM172 -> TelingaPre high gain -> D50 Line Input
2xEM172 @ 2ma/overvoltage -> D50 Mic
2xEM172 @ 2ma/overvoltage -> D50 Line input.
2xEM172 battery box + transformer -> D50 Mic Input
-Mike.
