Microphone Reviews-Understanding 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. 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.
Starting us off is a look at the way that a condenser microphone works. These mics are as well referred to by others as the “capacitor microphones” as it is the case with the British. 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 made of a thin membrane which is so close in proximity to a metal plate that is solid anyway. The one feature that must be with the membrane, alternatively called the diaphragm, must be conductive-electrically-a must for the surface. Among some of the materials that you will find used for this are such as the gold sputtered mylar and for some other models more so the older ones, you will find the use of some kind of exceedingly thin metal foil. 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 essentially means that there will be a change in the distance that there is between the two capacitor plates which as well tells us that the capacitance will then vary as well according to the rhythm of the sound waves hitting the membrane. This by far and large is the working principle that sees sound signals change to electrical signals.
Condenser mics require power from an external source. In the days gone by, this would have been deemed as a great inconvenience but today thanks to innovation and inventions nearly all mic inputs offer the P48 phantom power that has been more or less been consider the international standard. Given the fact of their low-mass diaphragm, the condenser mics have a superior sound quality. This is given the fact that the diaphragm being so low in mass, it will be quite good at following the waves, far more accurately as compared to the dynamic microphones that have a heavy coil attached to the membrane.
