Wireless Microphones
Beat the tangling cables during an on stage performance with the wireless microphones. It is the best way to utilize the stage and getting a clear sound while not bothering about the microphone cables. The wireless microphone, as it is typically interpreted, is a microphone, which works without a cable. It uses various standards, frequencies and transmission technologies to replace the microphone's cable connection and make it into a wireless microphone. Some of the basic models use the infrared light whereas many of them transmit in the radio waves using UHF or VHF frequencies, F, AM or various other modulation schemes.
The wireless microphone is known to have awarded us with many advantages of using it, but it is not always the advantages that come along with it. To understand this well, we have compiled a list of advantages and disadvantages of a wireless microphone that goes as follows:
Advantages of a wireless microphone:
The basic advantage of the wireless microphone is the freedom of movement it gives to the artist or speaker.
You can get rid of the cabling problems of a typical wired microphone, generally caused by constant moving and stressing the cables.
Disadvantages of a wireless microphone:
Many microphones offer a limited range with it closing in an area under 100mts. or 300Ft. These are the cheap models but the really expensive models ca easily surpass this range.
Some of them can be responsible for a possible interference with other radio equipment or other microphones. The new models with many frequency-synthesized switch-selectable channels are now widely available and cost effective at the same time.
Since they are battery operated, they offer a limited operation time.
Sometimes they can produce noise or dead spots, generally in places where it doesn't work.
The number of wireless microphones operating at the same time and place gets limited due to the limited number of radio channels they have to use.
In the wireless microphone the system consists of three main components that are an input device, a transmitter, and a receiver. The input device provides the audio signal that has to be set out or transmitted by the transmitter. With the transmitters behind them, the wireless microphones cab be assorted in two categories which are
Handheld Wireless Microphone
More like the conventional microphone with the basic difference being that in place of the cable this is bit bigger to house the transmitter and the battery pack. With the wireless microphone, wide arrays of microphone elements or heads are available.
Body pack Wireless Microphone
In the body-pack microphone the body-pack is a small box, generally the size of a cigarette packet, houses the transmitter and the battery pack. The body-pack transmitter easily clips to the user's belt or can be worn on the body. Generally for the instrument applications, a body-pack transmitter is often clipped to a guitar strap or attached directly to an instrument such as a trumpet or flute.
