People whose lives are closely connected with singing should pay attention to the wireless vocal microphone. It is much more convenient to sing and move if the wire does not hang around you. What they are, how to connect them and what to look for when buying, we will tell in our article.
How does the wireless microphone work?
As in other wireless devices, the transmission of the signal from the microphone to the amplifier occurs via infrared rays or radio waves. The latter are used more often, since they provide a large range (up to 100 m) and penetrate obstacles (walls, columns, wood, etc.).
Working wireless radio microphones is very simple. Sounds issued by a person go to the transmitter, which in turn, transforms them into radio waves. Receives them remotely located receiver and outputs to speakers.
The source of radio waves can be located both in the microphone (in the manual model) and in the lumbar rectangular block, which will be connected to it by a wire. For any type of transmitter, there must be an antenna. It can be built-in or external. Like all wireless devices, it works on batteries. These can be batteries, finger or battery-pills.
Wireless microphone is an excellent solution for karaoke , for conducting and organizing concert numbers at various events. You will calmly move around the site without fear of tripping over the wire, and your voice will be heard well.
How to connect a wireless microphone?
Make it so that the wireless vocal microphone is working, it's very simple. To begin with, you need to turn on the microphone itself (there is usually a start button on its foot) and connect the receiver to the network. It must be tuned to waves of the same length (VHF, UHF or IR) with the transmitter. After that, the receiver should be connected to the speakers (this can be a concert audio system, separate speakers or monitor headphones).
How to choose a wireless microphone for vocals?
Each microphone produced has a specific purpose (for vocals or instruments). Also there are universal ones, but if you want to get a good sound, then you should take specialized ones.
In the transfer of singing, it is very important to maintain sound quality, therefore the technical characteristics of the microphone itself and the radio transmitter should be paid the greatest attention. These include the type of membrane, acoustic pressure, sensitivity zone, power, stability of the carrier frequency, as well as the range of acceptable frequencies.
The next important factor in choosing a wireless microphone is the time of continuous operation without recharging. Naturally, the longer, the better. After all, if the microphone stops transmitting the signal, then no one will hear you.
In form, wireless microphones are hand-held (the usual form) and mini. The latter, in turn, are divided into petty or
Professional wireless microphones are quite expensive. Shure, AUDIX, Sennheiser, Audio-Technica and Rode models are of good quality.
Even for the best equipment, the correct placement of the antenna and tuning of the transmitter are required, otherwise the signal will be transmitted with interference, which will necessarily affect the quality of their sound speakers.
