Dynamic Microphones in Nigeria

DYNAMIC MICROPHONES

What is a DYNAMIC MICROPHONES in Nigeria?

Dynamic microphones operate on the same principle as a dynamic loudspeaker, except that they are designed to work in reverse. They produce an electrical signal when vibrated by sound waves. A diaphragm forms one side of a tightly enclosed, all-around magnetic circuit while a permanent magnet is mounted to the back of the diaphragm. Sound waves cause the diaphragm and attached coil to move backward and forward between the poles of the magnet. As this happens, an electrical current is produced in the coil. This type of microphone is rugged and relatively immune from interference caused by rf energy or power lines since it does not have a sensitive internal preamplifier stage.

Dynamic microphones are used for a number of applications. In public address systems, they are often chosen because of their good characteristics for non-musical sound sources such as speech and machinery noise. Since these microphones overload slowly, they also work well on loud sound sources such as rock bands. They have a wider frequency range than condenser or ribbon microphones and can provide very high volume levels before distorting. Dynamic microphones are not usually used where the source will be recorded since the recordings may exhibit distortion arising from the compressivity of the microphone's response characteristic. The moving coil units in dynamic microphones must move air when reproducing low frequencies thus requiring that the microphone be placed relatively close to its intended sound source (hence proximity effect).

Benefits of buying a DYNAMIC MICROPHONES on Jiji.ng

The dynamic microphone is the most rugged of all mics, making it an ideal choice for live concert performances. It's less susceptible to wind noise and has a wider frequency range than condenser or ribbon microphones. A good example of this mic in use can be heard on Led Zeppelin's live recordings (especially those made at Madison Square Garden) where they are often used for vocals, drums, guitar cabinets and sometimes saxophone. However, its most common application is for instrument amplifiers in studio recording.

A dynamic microphone is typically more resistant to moisture and humidity than other types of microphones with some models being very highly water-resistant/proof such as the Shure SM58). Some high-end microphones have switchable attenuation.

Reasons why you should buy a DYNAMIC MICROPHONES on Jiji.ng

Dynamic microphones typically have high impedance, requiring a current-providing device such as a microphone preamplifier and thus they produce lower signal levels than condenser microphones. They also generally produce lesser sound pressure level for a given electric audio input level, compared to condenser microphones. This is due in part to the distance of the diaphragm from the power applied to magnet coil acting on it, which can be controlled by varying the size of the gap between the pole pieces of an electromagnet. As well, dynamic microphones are typically unidirectional rather than bidirectional (although there are exceptions). The other factor affecting SPL is how 'tight' or 'loose' the membrane suspension is; tight suspensions offer higher

How do I maintain a DYNAMIC MICROPHONES in Nigeria?

No special maintenance is normally needed. Maintain the cleanliness of the microphone by wiping it off with any soft dry cloth or tissue after use. Avoid getting moisture, dust or contaminates inside the grille mesh to prevent damage to the element.

Do not touch or put pressure on diaphragm as it could cause distortion in sound output.

Avoid high humidity and temperature extremes when possible since they can affect condenser microphones adversely by causing thinning of internal oils which could lead to failure of internal parts over time.
