Hi, I'm Gary Boss, the National Marketing Director for Audio Technica and im here at Sonic Electronix talking about Condenser Microphones.
All mics are transducers meaning they convert one form of energy (in this case mechanical) into another form of energy (in this case electrical).
I have brought an example of a condenser mic...Also called capacitor mics because of the design. A very thin diaphragm which is coated with a conductive material (usually gold) is suspended above a back plate. Either the diaphragm of the backplate has a charge. This charge is either provided by an external powersource as in externally-polarized condenser or there is a permanent charge which is called an electret condenser.
As the diaphragm moves the capacitance of the circuit which changes its electrical output. This change is very small and must be amplified in the microphone by small amplifier called an FET.

Condenser mics can be extremely high quality. The diaphragm can be very light, rendering a flat...
