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. 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. Read on and see some of the reasons for this.
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”. From our elementary physics knowledge, we know of capacitors to be formed of two metal plates that are places in close proximity. It is by and large from the same lessons in elementary physics that we get the idea that the closer the plates to each other, the higher the capacitance. In essence, this is the same construction principle behind 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. 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. 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.
To use them, the condenser mics will need to be powered by an external power 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. 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 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.
