Wireless Microphone Buying Guide

By: Victor Epand

A microphone that comes without a cable and that can be connected directly to the sound recording or amplifying equipment is a wireless microphone. A German equipment manufacturer claimed in the year 1962 that they invented the first wireless microphone.

Though various individuals and organizations claim that they were the first to invent it, history says that Rex Harrison made the first use of wireless microphone for his film My Fair Lady in the year 1964.

While buying a wireless microphone one should be aware about which kind of system suits the need the best. Apart from this, the buyer must have a good knowledge of the situation for which it is being bought. Setting up of wireless technology is a bit difficult because the whole process is not limited to only plugging in and out. So, before going for this microphone a precise and clear technical knowledge is essential.

Whatever be the type of the transmitter, the buyer must check the battery to determine whether it is fresh or not. You should remember that battery life varies from system to system and if the battery has served more than half the assured life it must be replaced.

Various kinds of frequencies and transmission technologies are also to be taken care of. Wireless microphones have the ability to transmit radio waves with the help of UHF or VHF frequencies, FM or AM. The VHF Microphones are fixed frequency type and therefore the user cannot switch over to other frequencies if hindrance occurs.

UHF microphones can be operated in a place only depending on the national regulation of the country. In some countries the government considers all radio frequencies as their military assets. Not only this, using radio transmitters and wireless microphones is considered as a punishable offense. So their use requires a license issued by the government.

The use of wireless microphones has both advantages and disadvantages. They save the users the troubles caused by a constant moving of the cables. Thus the artist or the user can enjoy the freedom of movement.

One of the disadvantages of wireless technology is that it can be operated only for a limited period of time. There is the possibility that interference of other radio equipments may affect the system though this may vary from model to model.

The other points that a buyer must keep in mind are that the microphone should be easy to hold so that the hand can be rested in a comfortable position. This is equally important when wireless microphones are bought for the purpose of live performances.

The microphones must be able to handle high Sound Pressure Levels or SPL. There might be buyers in the market who are technically not so knowledgeable. They must always ask for the user manual to know how it is operated
