Radio or Wireless Microphones
Mostly they are known as the radio or wireless microphones and it is because their original audio cables were done away with and replaced with some other frequency transmitter method. They use radio waves like FM, AM, UHF, VHF and other digital methods.
The higher types have many frequencies for transmission and they hardly get clogged up or get any interference from other electric transmitters that could be within the same range of frequency. That is why they allow a number of microphones to be used simultaneously.
Initially, these mics were of compander microphone development which started all the way in 1976, and operated by Nady Systems. They became famous in 1996 when they got an Emmy for the technical advancement and contribution to the technological world.
Their numerous advantages range from their hygienic state that enables the user to keep health and safety rules while at work. They are not exposed to unhygienic conditions that the microphone codes used to impose on people who used them as they trailed along every imaginable surface.
They are now very convenient if one is moving around with them because they have no codes. Actually the codes attached to the old type of microphones used to be pulled and tagged too much. This tended to cause damage very easily to the microphone itself plus the cable too.
They might have more advantages but they also have disadvantages too. They use very expensive battery types as they require much more power than people think.
Their signals do not cover a long range and they are normally interrupted by other electric gadgets around them. This can only be overcome by getting very strong and powerful batteries which would automatically add to your cost.
This problem of frequency interference always causes a concern and can necessitate that one reduces the number of microphones that can be used in one area or within a given range.
