What is a Wireless Microphone?
A wireless microphone is a type of microphone that does not use a cable to connect it to the sound source. Instead, it uses a radio signal to transmit the sound signal from the microphone to the sound source.
Wireless microphones are typically used for events that require users to move freely, such as concerts, exhibitions, and meetings. This allows you to produce sound without being limited by the length of the cable.
How Wireless Microphones Works
How wireless microphones works depend from two main components, namely transmitters and receivers. The transmitter is the part of the microphone that sends sound signals to the receiver. Here’s how it works in more detail:
- The microphone captures sound waves: When sound occurs, the membrane inside the microphone converts it into an electrical signal.
- The transmitter converts the electrical signal: The electrical signal from the microphone is converted into a radio frequency (RF) signal, which is then transmitted through an antenna.
- The receiver receives the RF signal: The received radio signal is connected to a sound system or recorder.
- Sound amplification: The radio signal is converted back into an audio signal and amplified through a speaker or voice recorder.
Transmitters and receivers typically use radio frequencies to communicate with each other. The radio frequency used must be unique so as not to interfere with other radio devices. Usually, the code used is also unique to prevent eavesdropping on voice signals.
Types of Wireless Microphones
There are several types of wireless microphones to choose from:
- Handheld microphones: Microphones that are held in the hand, ideal for singers or speakers.
- Lavalier microphones: Small microphones that can be attached to clothing, suitable for presentations.
- Headset microphone: Worn on the head, very practical for sports or stage performances.
- Shotgun microphone: Typically used for film production and creative content.
Tips for Choosing a Wireless Microphone
Not only knowing how wireless microphones works, you also need to know how to get the best microphone. There are several things you need to consider before buying one. Here are some things to consider:
Sound quality
Sound quality is the most important thing when using a wireless microphone. Make sure you choose a microphone that has natural clarity without distortion.
You can also choose one with frequency response and responsiveness specifications. In addition, to avoid noise, you can choose a mic with low self-noise.
Range
Even though it is not tethered by a cable, that does not mean a wireless microphone has no range limitations. The limitation is the range itself. These microphones have a range starting from 30 meters for entry-level models, 100 meters for standard models, and 1000 meters for professional long-range systems.
You can adjust the range for indoor or outdoor use. For indoor use, you may not need too much range.
Batteries
Since they do not rely on cables, wireless microphones require batteries as a power source. You can check how long the batteries will last before purchasing them. Generally, batteries can last 4 to 12 hours. Also, make sure whether the batteries used are rechargeable or disposable.
Choose the type according to your needs
As is well known, there are several types of wireless microphones that you can choose from according to your needs. You can choose handheld microphones for singing or public speaking.
For those of you who want to look seamless without having to hold a mic, you can choose lavalier microphones because they can be placed on your clothes. For stage performances, you can choose a headset microphone. Meanwhile, for film production, you can use a shotgun microphone.
Price
Wireless microphones have a wide range of prices depending on their range and sound quality. You can adjust your microphone to your budget. That way, you will get the best quality within your budget.
By considering these factors, you can choose a wireless microphone that suits your needs.
Ultimately, wireless microphones are the best solution for those who need uncompromising sound quality. With this article, we hope that you will not only understand how wireless microphones works, but also be able to choose the one that suits your needs.
For additional information, you should know that every wireless product on the market must meet the standards of the Directorate General of Digital Infrastructure (DJID) certification. Therefore, it is important to ensure you use a certified wireless microphone to ensure safe use.
