What Basics You Need to Know of about the Condenser Microphone
The first question that we will seek answers to is that of what 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 fundamentally the very principle that happens to be with the construction of the condenser shell. The condenser capsule is made of a thin membrane which is so close in proximity to a metal plate that is solid anyway. As one characteristic that is of a must of the membrane or otherwise known as the diaphragm is that it must be electrically conductive, at least on their 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. 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 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. 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 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.
