What Basics You Need to Know of about the 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. Read on and see some of the reasons for this.
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. Basic physics teaches that a capacitor is merely two plates of metal that are placed close one to the other. The same class tells us that the closer the plates the higher the capacitance. In essence, this is the same construction principle behind 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. 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. 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. It working mode is such as when sound waves hit the membrane, it gets to move comparative 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. As a result of their low-mass diaphragm, the condenser microphones will prove to be a lot better when it comes to 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.
