A wireless microphone has the function of capturing sounds to transmit them through radio frequency waves . So, like a radio, wireless microphones are equipped with an FM or AM transmitter . The transmitter and receiver pair that make up all wireless microphones must work on the same frequency in order to transmit the sound that the microphone picks up. This does not mean that a wireless microphone cannot work on a single frequency, simply that a specific frequency must be chosen in order to synchronize the receiver with the transmitter. Depending on the use of the microphone we can finddifferent ranges for example in the case of professional wireless microphones we have between 40 and 50 megahertz . While for wireless amateur karaoke microphones we have a short range band between 88 and 108 megahertz. While UHF and VHF receiver wireless handheld microphones have bands of 900 and 470 megahertz. By occupying a radio frequency space, the frequency band for wireless microphones is set by the Government of each country to avoid interference between wireless microphones and, for example, radio or television signals.
Another of the characteristics that must be taken into account is that the microphones, being wireless, depend on a power source, normally through a 9 volt battery . So if you are going to buy a microphone to sing you should take into account the battery status indicator . There are many professional singers or karaoke fans , who run out of battery when singing and not taking into account the battery indicator of the wireless microphone . This is why the battery is a very important part in every wireless microphone, and must be checked before each professional use.to avoid feeding problems. Although in any case it is recommended to always have a spare battery or batteries available. As we said , 9V batteries are usually used for offering a longer life , although 9V batteries can also be used when the wireless microphones are going to be used professionally for less than three hours.
Types Of Wireless Microphones
There are currently basically two types of wireless microphones : so-called lavalier or lavalier microphones , and handheld microphones such as the baton type used by professional singers or wireless handheld microphones for karaoke . When buying a microphone to sing it is important to know what type of song or performance is intended. For example, a professional singer will need a cane microphone more , especially if he also plays an instrument in addition to singing. While for non-professional singers, such as those who sing inKaraoke or private parties , the wireless handheld microphone is the best solution. Because those types of microphones are the ones that offer the singer the most mobility . In any of the above cases, wireless microphones will always be a better solution, especially for stages and conferences , to avoid falls and tangles with the cables. And although non- wireless microphones are cheaper , in the end it deserves to pay the difference for greater mobility . The only thing to keep in mind that to avoid radio frequency interference , the microphone must be separated by a minimum of 10 meters. So it is important to consider that distance when buying a wireless microphone.
Choose Wireless Microphones For Professional Use
Once we are clear about what a wireless microphone is and the main types that exist in the market, we must bear in mind that choosing the correct wireless microphone depends a lot on the use that it will be put to. So we will explain some possible professional uses for choosing the right wireless microphone:
- For singers on the move, fitness or zumba gym monitors , or dance teachers. The most suitable is the wireless headband microphone , that is, the one that is attached to the head, and with a hip flask. It has the advantage that they are comfortable and easy to use, offering great sound quality despite physical activity.
- For presenters, theater actors , or middle managers and company managers, the best option is the lavalier microphone with hip flask . Since this type of professional use requires freedom of movement in the hands. Since they complement their oral presentation with the non-verbal language of their hands. In addition, these types of wireless microphones are the least sensitive to external noise such as breathing.
- For musicians there are different options, depending on the type of instrument. For example, for brass instruments or percussion, choose wireless microphones with instrument clips and hip flasks . While for instruments such as guitars and basses the best solution is to choose wireless microphones with instrument clips and hip flasks. Its fixing systems offer a secure as well as precise placement.
- For professional singers it depends a lot on what type of performance you are going to perform on stage in order to take care of the live sound as much as possible. So for these professional uses you have to choose a wireless condenser microphone to sing at a low level.
