Wireless microphones are an important tool in a range of applications from music-making to filmmaking and broadcasting. Without them, performers and speakers would have no way to connect their microphones to an audio console or recording device.
They are used in theaters, sports venues, music venues, film studios, conventions, corporate events and houses of worship. They are also widely used in education settings.
Less Interference
Interference is a common issue with wireless microphones. It can interfere with sound quality, reduce range, and even cause a dropout.
It’s also a source of frustration for users. If interference is not resolved, it can affect audio performance and the way a system is set up.
First, identify the source of the interference. This is usually easy to do. It may be a computer, digital delay unit, effects processor, lighting controller, or other devices that use microprocessors and digital signal processing (DSP).
Second, try to find out how far the interference travels before it causes problems. If it is within a few feet, the problem may be caused by interference with the receiver antennas or transmitters.
If the interference is occurring at greater distances, it could be caused by direct or intermodulation interference. Direct interference occurs when another strong radio signal reaches the receiver’s antennas. It can create a range of audio problems from weak tones, whistles and whines to harsh noise.
Better Audio
Whether you’re performing, presenting or recording your voice, wireless microphones can help you achieve better sound. They don’t need a cord that can get tangled or become a nuisance, and they come in a variety of sizes and styles to suit your needs.
The audio you hear from your microphone is often impacted by interference from other devices, such as computers and TVs. This can lead to artefacts, such as ‘clicks’ and ‘pops’ in your voice.
Digital systems can transmit pure digital signals, which are not affected by the transmission medium, reducing or eliminating this issue. However, some digital systems may experience latency, which can be frustrating to both performers and audiences.
If you’re a performer, look for a wireless mic that offers adjustable gain to prevent clipping or maximize the signal-to-noise ratio. Some models also have an adjustable squelch, which silences the output when the microphone’s output is not strong enough to be heard through the receiver.
Easier to Move
The freedom to move around is a huge plus in a lot of situations. It’s a great advantage for teachers, worship leaders and fitness instructors, for instance, as it can make their performances much more enjoyable and safer than they would be with wired microphones.
Wireless mic systems consist of three main components: a transmitter (often worn or held by the performer), receiver and signal cable. The transmitter broadcasts a radio signal to the receiver, which converts it into an electrical signal that can be sent to your audio console or recording device.
Although a wireless mic system can save you time and money in the long run, it’s still best to be aware of some important wireless microphone facts before you decide whether or not to invest in one. This includes things like frequency selection, battery life and range.
More Affordable
Wireless microphones are a great option for musicians, presenters, and other live performers who want the freedom of cordless devices without the tangle of cables. They come in a variety of forms including handheld, headset and lavalier options.
The most common types of wireless systems use VHF and UHF radio frequencies to transmit signals, which offer a good range for these devices. Unfortunately, this spectrum also contains a lot of competing signals that can introduce RF noise and make your signal more prone to dropouts.
Some systems utilize pure digital technology, which offers higher sound quality, wider frequency spectrums and fewer interference problems. However, they also cost more than analog systems. They also require battery power, which means they will need to be recharged frequently.
