What Basics You Need to Know of about the Condenser Microphone
What we will first of all seek to address is to see what it is that a condenser microphone actually 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. Here is a look at some of the reasons why this happens to be so.
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. 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. 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. 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.
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. As a result of the fact that they are so of low-mass membranes, the condenser microphones are known to provide superior sound quality. This happens to be so for the fact that they being as low in mass, they will be a lot more effective in following the sound waves as compared to the dynamic microphones that have such a heavy coil attached to them.
