Different kinds of wireless microphones and their benefits

A wireless microphone is, as the name implies, a microphone without a physical cable that connects it directly to the audio recording or amplifying equipment to which it is connected. Wireless microphone systems are a key component in almost all broadcast, film, theater and sound image productions as well as corporate, religious and educational venues.

The professional models transmit in VHF or UHF radio frequency and have true diversity reception, which eliminates dead spots and the effects caused by reflection of the radio waves on walls and surfaces in general. The VHF band is located in the frequency range between 30 MHz and 300 MHz. This is the second common band used in wireless microphone systems, but it is not as commonly used as UHF.

Wireless VHF microphones are typically those of the fixed frequency type, which means that the user does not have the option to change the frequency if interference occurs. The UHF band is located in the frequency range between 300 MHz and 3 GHz and is the most common band used in wireless microphone systems. Depending on different national regulations, wireless microphones may operate in the range of 470 MHz to 865 MHz. These frequencies are shared with over-the-air TV broadcasts. So when choosing a frequency, the user needs to know which frequencies to stay away from to avoid interference.

Advantages and disadvantages of wireless microphones

The main advantage of a wireless microphone system is its freedom of movement. Since a wireless microphone is not connected to any cable, the user is not limited by the cable length. Wireless microphone transmits audio signals over the air rather than through microphone cables. The microphone is connected to a transmitter, and the signals are received by a receiver connected to the audio console or recording device. The user can avoid cable problems that often occur due to the constant movement and load of the cables.

Although wireless microphones are in use everywhere, it also has its drawbacks, regardless of its advanced technology. It has only a limited operating time due to low battery life. It does not work if the user takes the microphone out of range. Occasionally there may be interference with other radio equipment or other microphones.

Different types of wireless microphones

In general, they are two types of wireless microphones - handheld wireless microphone and bodypack wireless microphone. Handheld microphone is like a normal wireless microphone, but it has a larger body to accommodate the transmitter and battery pack. The Bodypack microphone is a small box that contains the transmitter and the battery pack, but not the microphone itself. It can be attached to the belt or elsewhere and has a cord that goes to the headset, lavaliere microphone or a guitar.

Some manufacturers of wireless microphones offer a connector on the transmitter for existing wired microphones that connect to the microphone's XLR output and transmit to the receiver. This offers many of the benefits of an integrated system and also makes it possible to use microphone types without cable https://www.amazon.com/Wireless-Microphone-Rechargeable-Transmitter-Recording/dp/B082KGC61N
