Microphone Reviews-Understanding the Basics of a 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. Below is a look at some of the reasons.
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. 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 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 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 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. We would have quite considered this to be an inconvenience in the days that were past but in the present dispensation, hail invention and innovation, we have barely all the mic input with the P48 phantom power that has been more or less been considered to be the standard across the board, internationally. Given the fact of their low-mass diaphragm, the condenser mics have a superior sound quality. This is as a result of the fact that there happens to be such an effective follow of the sound waves by the diaphragm as it is so low in mass as compared to the dynamic microphones that have such a heavy coil attached to the diaphragm.
