That's what the transformer is for. Although I will say it again, it is not impedance matching. It is a voltage step-up. Impedance matching in microphone circuits is a myth. This is well documented on the internet. Impedance matching is only important when you are transferring power. In fact the pro audio world recommends that the load impedance be 10x the microphone impedance.

One thing of note that I will repeat here is that the element itself -- disconnected from the rest of the mic -- measures 430 ohms with my Fluke 77 in resistance mode. That seems odd if the thing is supposed to be high-impedance.
