Wireless Microphones: The Ultimate Buyer’s Guide

Wireless microphones allow performers to move freely around the stage without fear of tripping over cables. Musicians, teachers, corporate conference rooms, and worship places in Australia may benefit from using a wireless microphone system. A microphone’s system may be a good match for your school, theatre, or karaoke bar, so check out the buying guide to get started.

Frequency

UHF is the most often used of several possible frequencies (up to 400 MHz) in Australia. Its working frequencies have lately been regulated by the Federal Communications Commission (FCC). There is a chance, though, that these frequencies will change. Frequencies between 470 and 548Mhz are ideal for long-distance and clear transmission.

Other systems may also be found in this frequency range. Microwave ovens may interfere with wireless devices operating in the 2.4GHz frequency band. Thus it is vital to be aware of this. They also have a far smaller operating area than their predecessors. 2.4GHz can only be used in limited places with no impediments between the transmitter and receiver antennas.

Professional microphones often use the 902-928Mhz frequency band. The 600-700Mhz frequency range has proved to be a popular replacement for 600-700Mhz microphones. Note that 700 Mhz microphones are now banned, and frequencies between 566 and 698Mhz were limited in 2020. Stop using these microphones and get new ones that operate in legal frequency bands instead. Certain manufacturers will also provide VHF in the 169-216Mhz band. New digital technologies may one day allow for this choice to be considered.

The system’s capability

Make sure you purchase a microphone setup that has double the range of what you want. You must have at least 1,000 feet of wireless coverage in your system at all times. A long-range microphone system is recommended even if your working space is just 900 square feet and there are no obstructions.

Additionally, short-range wireless systems suffer from signal degradation when travelling through pulpits, tables, doors, and sound booths. A 2.4Ghz or VHF system will not have the same range as a UHF system, so keep that in mind while shopping around.

A microphone system’s capacity to function

A free microphone does not exist. Is it possible to identify which systems are trustworthy before making a purchase? Less costly systems may include components that are more susceptible to failure and may not be compatible with each other. Find a microphone system with low noise and low dropout. Determine whether the construction noise reduction is of the companding kind. Compression and expansion are two phrases used in computing to describe how a signal is compressed before it enters and enlarged after it exits your system. Your listeners may be annoyed by the pumping noise that certain noise-reduction technologies make.

In terms of sound quality, digital vs analogue

Digital microphone systems provide several advantages over analogue systems, including longer battery life (up to 40% longer) and improved spectral efficiency.

Analogue wireless microphone employs a compressor/expander called a companion to capture the entire dynamic range of a sound source because of the restricted frequency allotment available for microphone use.

A broad dynamic range may be achieved by transmitting an uncompounded digital signal instead of depending on companding. As a result, the sound has a more authentic quality. Price reductions have made digital microphone systems more accessible to the general public. The transmitter of specific microphone systems can be modified remotely by using a computer network to the receiver
