Wireless Microphone Frequencies

Wireless Microphone Frequencies

Are you a New Zealand broadcaster who uses wireless microphones or in ear monitors? Are you aware that in 2015 changes come into force that mean your equipment may no longer be legal?

Changes in frequency allocation (named digital dividend) affect all users of wireless microphones or in ear monitors. Currently such equipment can be used in the 698 to 806MHz frequency range. This range of frequencies has been reallocated to provide for 4G mobile broadband services. To protect these new services from interference, radio microphones are no longer permitted to use this frequency range from 11 March 2015.

From 11 March 2015 onwards, all wireless mics and in ear monitors must use the new frequency ranges of 502-606MHz and 622-698MHz. Southern Broadcast recommends that you aim to operate equipment in the range of 614MHz to 694MHz since this contains the largest number of clear frequencies to use across New Zealand. The maximum permitted output power of wireless microphones and other equipment on these frequencies is -3dBW (500mW), but this comes with certain conditions. The user of equipment must ensure that interference will not be caused with TV services existing on the same band. If you are unsure, or there are other services using the same frequencies the user must limit equipment to -20dBW (10mW). Southern Broadcast can advise what power and frequencies you can use in your area.

If this issue effects you Southern Broadcast can help. You might be able to retune exiting equipment to the new frequencies, or you may need to purchase new equipment. Southern Broadcast can advise the most cost effective way to ensure you remain compliant under the new frequency allocations. You can read more information on the Radio Spectrum Management’s website.
