A Review on the Basics of a Condenser Microphone
To get us on the path, we will first of all seek a probable description of what a condenser microphone really is. In as much as the dynamic microphones have been considered as some of the best when it comes to stage performance all given their rugged construction and design, the condenser microphones have as well come to have their fair share of acclaim in the market being the favored choice when it comes 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. For the Britons and the like people, the condenser mics are as well known to them as the “capacitor microphones”. What we get from the low level physics knowledge imparts in us the knowledge that a capacitor is essentially made of two metal plates that are placed close one to the other. 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. The condenser capsule is actually consisting of a thin membrane which is actually placed in such close proximity to a solid 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. In this you will find the most common materials used being such as gold sputtered mylar and for the traditional models you will meet those made of some extremely thin metal foil. This works in the sense that when the sound waves will get to hit the diaphragm, it gets to move back and forth as per the solid backplate. What this means is that the separating distance between the two plates changes, which eventually translates into a change in the capacitance according to the rhythm of the sound waves. Here you see the basic principle at work when sound signals are converted into electrical signals.
To use them, the condenser mics will need to be powered by an external power 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.
