Microphone amplifier in modern sound recording
Many of us, using at home or at worksuch a device as a microphone, never thought about the difficulties encountered by manufacturers of this type of devices that enhance and transform your voice or music.
It would seem that nothing complicated. For many of us, the microphone is just a small device that seems much smaller and easier to use than the same headphones or dynamic heads. Starting with the first batches of microphones released from the production lines (the mandatory element of which is a microphone amplifier), there have not been any significant changes in their design. Whether it's microphones for use, for example, in espionage, or for recording music, the principle of their work remains the same: how can the sound vibrations of the air be transformed into electrical vibrations that are understandable to most sound-reproducing systems.
However, to qualitatively transform sounds inelectrical signals are not so difficult, it all depends on the elements of the microphone, such as the membrane, the amplifier for the microphone, the mechanoelectric part. It is much more difficult, as it turned out, to ensure high quality of the converted signal and, accordingly, to achieve its amplification, make it understandable for the audience.
The legendary rock band "Time Machine", makingthe emphasis in his work on the semantic load, really faced with such a problem as the delivery of the meaning of the work to the audience. And when the hall heard the text of the songs, he froze.
No matter what the microphone is made of, it's goldor platinum, from a technical point of view it is important which microphone amplifier converts the signal, through which filters the oscillations pass, etc. Much depends on the acoustics of the hall, the skill of the sound equipment operator and the artist's skill. Agree, I would not like to face the previously widespread effect, when after the phrase spoken in the microphone, the result was a monophonic sound at the limit of the power of the equipment used, arising from the resonant effect when using a microphone.
Today, most of the problems thatthe dawn of widespread use of microphones, successfully solved by engineers. Specialized amplifiers have appeared that make it possible to increase the power of the audio signal practically without interference and to give it to amplifiers of audio frequency that work on sound reproducing systems.
There were developments protected from the majorityinterference inherent in the original products. The industrial production of such a component of the device as the microphone amplifier, at the moment can offer a wide range of various products, not available to users, for example, 15-20 years ago.
Despite the proposed diversity of speciesexpensive studio amplifiers, the relevance of simple devices has not become less. Not every recording studio can afford to buy an expensive amplifier, in addition, in a limited budget home studio also does not make sense to the cost of an expensive device. After all, the microphone amplifier is quite easy to assemble with your own hands. There are video clips on the Internet, in which the process of independent production of this microphone element is described in detail.
Microphones are used in various areasthe life of a person, starting from everyday life and ending with production. In popular television series, we often observe how the hero summons rescue services to the scene and, thus, saves the world from destruction. I wonder how he would do it without devices using a microphone and a microphone amplifier in their work?
