Many wireless audio devices—such as wireless microphones—were retuned or replaced by the start of 2015 because of changes in access to the radiofrequency spectrum.

Many wireless audio devices—such as wireless microphones—were retuned or replaced by the start of 2015 because of new radiofrequencies these devices can use. Some devices needed no change.

What is a wireless audio device?

Wireless audio devices include:

  • wireless microphones
  • in-ear monitoring systems
  • public announcement (PA) systems
  • musical pick ups
  • wireless transmitter and receiver units.

These devices use the vacant spectrum ('white spaces') between broadcasting or other services. The devices use spectrum under class licensing arrangements. This means you can use these frequencies for free as long as they do not cause interference to other services.

What wireless audio devices and frequencies can you use?

You can use devices that use these frequencies:

  • 88 to 108 MHz
  • 174 to 230 MHz
  • 520 to 694 MHz
  • 1790 to 1800 MHz
  • parts of the 900 MHz, 2.4 GHz and 5.8 GHz bands.

Not all frequencies are available everywhere in Australia. Before you buy any equipment:

  • Use ACMA’s channel finder to check what is available in your area.
  • Read ACMA's fact sheets and FAQs if you use equipment in more than one area.
  • Ask your equipment supplier or manufacturer about what will work in your area.

What can you do with old equipment?

Wireless audio devices can’t use the 694 to 820 MHz frequency range anymore because it’s illegal. You will need to retune or replace any equipment that works in this range:

  • If your equipment works below 694 MHz, you might be able to retune it to the different frequency range available in your area. Check your device (or its handbook) or contact your supplier. The wireless microphones hub on the ACMA's website has more information.
  • If your equipment can’t be retuned, you will need to replace it. This means you will need to dispose of it safely and buy new equipment. The Australian Communications and Media Authority (ACMA) has a list of useful links to suppliers and equipment deals.
