Wireless microphones are ubiquitous today in modern communication. They are used everywhere, ranging from the recording studio rooms and filmmaking to journalism and education. You might think what it is that makes them popular among the masses.
Working of the Wireless Microphones:
The working principle of wireless microphones is almost the same as wired ones. The one big difference between the two is that the wired mic is reliable on the cable to carry the signal. On the other hand, a wireless microphone relies on the radio transmitter for broadcasting the output signal. The functions and frequency of these microphones increases with the transmitted audio signals.
Components of a Wireless Microphone:
A wireless microphone system has three pieces, namely:
Microphone-
The first part of the system is just like any other microphone. Wireless mics work as transducers, which change the sound energy into audio signals. The sound waves vibrate the diaphragm of the microphone, which is then converted into an electrical signal either through variation in the condenser or the electromagnetic induction. The signal might or might not be amplified inside the microphone before producing the output.
Transmitter-
As the name suggests, it works by transmitting the audio waves through radio waves. The transmitter takes the output audio signal of the microphone, converting it to a radio signal while broadcasting it through an antenna. The transmitters come in three types – handheld, belt pack, and plug-in.
Receiver-
The receiver receives the transmitted radio frequency and reconverts it into the audio signal. The frequency of the transmitters is effectively without interruption if the frequency of receiver and transmitter are equally.
Guide to Purchasing the Microphones:
With wireless microphones, speakers and artists are free to roam on the stage without worrying about stepping over the cords here and there. To purchase a wireless microphone system, you must have some things in your mind, which are:
Frequency-
You can choose from several frequencies available with UHF being the most common one. To get excellent clarity and transmission, you might want to pick a frequency between 470 and 548 MHZ. apart from this, the frequency varies depending on the purpose you use the mic.
Range of The System-
According to the rule of thumb, you should purchase a microphone with the range twice you need. Usually, it is recommended to go for a long-range system.
The primary drawback of the short-range system is that it degraded the system when passing through doors, desks, and sound booths.
Digital vs Analog Quality-
One of the most important qualities you should look for is better sound quality, which you can get from the digital sound quality. These have become the preferred choice of many people, and their declining prices have made them even more popular.
Reliability-
Everyone wants to buy a reliable system, but the problem is how can you do it? You can investigate low-static, low-dropout, and low-noise microphone systems to get the best deal.
Some other things that you might want to consider include microphone type, latency, and battery life.
Benefits of Using Wireless Microphones:
The reason for the increasing popularity of wireless microphones over conventional cabled mics is the following points:
No hazards from mucking over the hazardous and messy cables
Provides ease of movement
Durable as radio waves don’t wear out
They can operate even if the distance between the transmitter and receiver is large.
Now that you know the right factors that play an important role in buying the microphone, don’t make any mistakes.
