[Elecraft] Ceramic microphone connections.

[David Quental]

Hello all,

I have bought a nice Ceramic microphone to use with my K3, however I am 
in doubt how to connect it. The microphone has 4 wires:
a ground wire;
a white wire;
a red wire;
a black wire.

According to mic schematic, the ground and white wires belong to capsule 
polarity (white for + and ground to ground symbol).

How should I connect these wires inside mic jack ?

White wire to pin nº 8 and ground wire to pin 7 or 8 ?

And about red and black wires, where should I connect them ?

Should I consider it as an electret mic or a dynamic one ?

Best 73 to all.
