A Review on the Basics of a Condenser Microphone

The first question that we will seek answers to is that of what a condenser microphone actually is. While the dynamic microphones have become so popular for stage use and this is thanks to their rugged construction, the condenser mics have actually cut themselves a sphere in the market being the preferred choice when it gets to studio recording. Below is a look at some of the reasons.

To begin with, we will take a look at how a condenser mic works. These mics are as well referred to by others as the “capacitor microphones” as it is the case with the British. From our elementary physics knowledge, we know of capacitors to be formed of two metal plates that are places in close proximity. We also know that the closer you get to have the metal plates, the higher the capacitance will be. This is essentially the basic construction model that goes into the condenser capsule. This is in the sense that the condenser capsule consists of a thin membrane that is quite in close proximity to a metal plate. One feature that must be present with the membrane, which can as well be referred to as the diaphragm, is that it needs to be electrically conductive at the minimums on the surface. Some of the most common materials used on these are such as gold sputtered mylar and in other cases you will find the use of a very thin metal foil, especially for the older models. It works in such a manner as when the sound waves will reach the membrane, then it sets in motion in relation to the solid backplate. This basically means that there will be change in the distance between the two capacitor plates which as well points to the fact that there will be a change in the capacitance all in accordance to the changes in the sound wave rhythms. This is basic principle applicable behind the conversion of sound signals into electrical signals.

Condenser mics require power from an external source. Formerly, this would be a great inconvenience but thanks to development, nearly all mics inputs has the P48 phantom power which has actually been regarded as the standard internationally. Given the fact of their low-mass diaphragm, the condenser mics have a superior sound quality. This is as a result of the fact that there happens to be such an effective follow of the sound waves by the diaphragm as it is so low in mass as compared to the dynamic microphones that have such a heavy coil attached to the diaphragm.
