Some microphones have transformer-coupled outputs, while others are deemed transformerless. Some microphones even have transformers in the middle of their signal chains rather than at their outputs.

What is a microphone transformer? A mic transformer is a passive electrical device that physically isolates two circuits while maintaining an electrical relationship between the circuits. Mic transformers have two conductive coils (one for each circuit) wound around a common magnetic core. They adjust voltage, current, and impedance.

In this article, we’ll discuss the role of the transformer in microphones as well as the microphones that use transformers and those that do not.

Impedance of the transducer itself is very high – many MΩ. Can be as good as 20 Hz to 20kHz or better. High quality sound recording, some sound support systems where additional sensitivity is needed.

Condenser Microphone: Capacitor Microphone
The condenser microphone or capacitor microphone is able to provide high quality audio.

As the name implies, the condenser microphone or capacitor microphone uses a capacitance that varies in line with the incoming signal to generate the varying output voltage.

The name condenser microphone still persists. The microphone was invented in the days when capacitors were still called condensers.

I assume you created specific nice points in functions also.
