Dual Wireless Microphone

A dual wireless microphone is a microphone that does not require a cable directly connecting it to recording or amplifying equipment. Essentially, they are a set of microphones that send their signal to a relay device, which is plugged into either a mixer, soundboard, or recording deck.

They are mostly used by public speakers at conferences and events, but can also be used for concerts and for practices at home. They are basically UHF systems, and operate based on a short range UHF signal.

Before we talk about the units themselves, I thought it would be interesting to discuss the origination of the technology, as the origins of this technology is often debated.

Oddly enough, various businesses and organizations claim to be the creators or inventors of the wireless microphone. In 1949 a guy named Reg Moore created a radio microphone and was first used in Aladdin on Ice. In 1951 John F. Stephens created a FM wireless microphone for a Navy musical on the Memphis Naval base.

Each players and singers had to have their own microphone or transmitter. The invention that Stephens created was modify and used only in government bugging operations. In 1951 Herbert Mac McClelland that was the founder of McClelland Sound and Wichita, Kansas, had fabricated a wireless microphone and it was to be worn by baseball umpires in a major league games that was broadcasted by NBC in the Lawrence Dumont Stadium. The transmitter was then strapped on the backs of one player in the umpire.

The first real recorded patent was by Raymond A. Litke who was a American electrical engineer with a Educational Media Resources and attended San Jose State College, in 1957 He had invented the wireless microphone to meet the multimedia that he needed for television the radio and for the classroom instructions. On May 19 1964 he invented the first portable wireless microphone. Finally a dependable wireless microphone was on sale. The range and sound was great and proved it was the same as having the normal corded microphone that used the cords and cables.

In 1960 there were two available for purchasing. In 1960 the Vega Mike was manufactured, which was after the Vega Elections Corporations had done it at the 1960 Democratic and Republican National. It allowed news reporters to roam the floors and have interviews and conversation without holding or standing to talk into a microphone. It also makes it easier when they are doing an interview with participants where presidential candidates Kennedy and Nixon became the first two celebrities to use the wireless microphones.

Today’s models of dual wireless microphones rely on very sound and secure technology, and are useful for everything from concerts to public speaking. Most of these systems can be had for less than a few hundred bucks, and are very reliable.

As with any wireless technology, you’ll want to take proper precautions to avoid feedback and interference. The first can be avoided by keeping the microphones away from each other and from the signal processing unit, while the second can be avoided by keeping the units away from other wireless devices, and even stronger wired devices, such as preamps and coax cable units.

As with most wireless units, dual wireless microphone systems require a direct line of sight between the microphone receiver and wireless microphones.

Some of the models can operate in a single fixed frequency, but there are more advanced models that allow you to use multiple frequencies, almost like a walkie-talkie, so that you can avoid heavily used local frequencies and or problematic frequencies. Still, for just a few hundred bucks, an amateur can’t go wrong with one of these systems.
