Audio mikes that used the cables for signal transmissions have long since been replaced with wireless mikes. Also called Radio mikes, they use radio frequency technology to transmit the audio signals. They are capable of sending signals through FM, AM, UHF, VHF and various digital formats.
Highly advanced mike sets are built with features that allow you to select the frequency with which you wish to transmit and thereby avoid interference from other instruments that might be operating in the same frequency. You can also use multiple microphones at one time.
The radio microphones are said to have their beginning in the original compander microphone that was built in 1976 by Nady Systems and received an Emmy award for his technology contribution in 1996.
Radio mikes are wireless and hence it is easier for the performers to use them on stage and it is a lot safer too when compared to the wires and cables dangling from wired mikes.
With Radio mikes that are wireless, the performers can be more relaxed and have ease of movement while performing. It enables them to move across the stage easily without having to tag the cable along. Secondly there is no need for cables to be joined and fixed together etc.
But then though they have such good advantages, they do have certain disadvantages too when it comes to the battery life. The two way radio batteries tend to get drained fast as the radio microphones guzzle more power in comparison to the cable mikes.
One other shortcoming could be the limited range within which the radio mikes operate. To get wider range you would have to buy higher models. There is also the risk of signals getting disrupted due to any other appliance or equipment operating within the same range.
Lastly to be able to get clarity and ensure clear frequency you will be constrained to limit the number of radio microphones that you use.
