Unidirectional Mic

Unidirectional Microphone

The microphone marketplace is averse with varied mics that are designed for different purposes. There are mics specially designed for general use, those that designed purely for recording purposes in studios or laboratories and those that can be used both for recording and general usage. The major difference in mics lies in how they operate or how they are designed to pick up sound. This depends on how the internal mechanism is constructed. A unidirectional mic picks up sound in a different way from the manner in which other mics pick up sound.

The unidirectional microphone is internally constructed to pick up sound from the direction it faces only. In doing so, the mic avoids any sound that may come from its rear. One can find a unidirectional mic in three main types; cardioid, hyper-cardioid and super-cardioid microphones.

A cardioid mic is constructed in such a way that it only picks sound directly from where it faces. It avoids picking sound that may come from either its sides or the rear part. This kind of unidirectional mic is very useful particularly for recording purposes, as it will not pick up any sound that resonates back.

A hyper-cardioid mic functions in the same way as the cardioid mic with the only difference being that while a cardioid mic only picks up sound from its front area, a hyper-cardioid unidirectional microphone picks up sound from both front and its sides, but avoiding any that may come from its rear area. However, the sound picked up from the sides is distorted. Like the cardioid mic, this kind of unidirectional mic is good for recording purposes.

A super-cardioid mic functions in the same way a hyper-cardioid mic functions; picking up sound from both the front and the mic’s sides while avoiding sound from the rear area. The only difference is that the super-cardioid type of unidirectional mic has extended range than the hyper-cardioid mic.

The fact that a unidirectional mic is only able to pick up sound from a direction only (its front) makes it the perfect mic for undertaking a recording that is clear of any unnecessary noise that may come from the rear part of the mic. It is particularly very effective in undertaking a recording of either one musical instrument or one vocalist. However, the unidirectional mic is very poor at picking up varied sounds produced by different instruments or vocalists. This requires the use of a mic that can pick up sound from different positions.

Unidirectional microphone that is used for recording purposes needs to have appropriate mic covers. This is despite the fact that a unidirectional mic is capable of avoiding unnecessary sound on its own. Mic covers enhance the performance of this mic while at the same time providing protection both to the mic and a mic’s user as well.

Mic covers are widely available from stores that sell mics and are sold as mic accessories. They come in various colors and are reasonably priced and therefore affordable. The unidirectional mic covers can also be used to protect a mic against wind if a mic is used outdoors.

There are various unidirectional mic manufacturers mainly in developed countries. They produce high quality unidirectional microphones that are available throughout the world and sold through different outlets. Although these mics may appear to be expensive, they offer high quality performance worth their price.
