From 1 January 2015, the 694–820 megahertz (MHz) frequency range will be used exclusively by telecommunications companies to provide 4G mobile broadband services. This means it will be illegal to use wireless microphones and other audio devices that operate in the same frequency range. Thankfully, ACMA is on the case…

The Australian Communications and Media Authority (ACMA) has introduced new regulations to restrict the sale of any wireless audio transmitter operating in the 694–820MHz frequency range. Suppliers are now required to inform customers if the equipment they sell isn’t suitable for use after 2014.

“Many community groups and small businesses use wireless microphones in their day-to-day work, ranging from school assemblies to local theatres to gyms and places of worship,” ACMA Chairman Chris Chapman said.

“The intention continues to be to give Australians as much time as possible to prepare for the changes and we strongly encourage people to check their equipment now. Anyone considering buying a new wireless microphone or audio device should check for the warning label and ensure they are buying a compliant one.”

However, rules are not always followed rigorously, especially when it comes to independent specialist stores. In other words, there’s a good chance that non-compliant equipment may continue to be sold without the provision of a clear warning. It therefore pays to do your homework online.

From 1 January 2014, suppliers will no longer be able to import, manufacture or sell wireless audio transmitters in Australia that operate in 694–820 MHz. Until then, make sure you pay close attention to the product’s specification prior to buying.
