Unfortunately we still come across many radio mic users who aren’t aware of the law changes back in 2015 and are operating their mics on illegal frequencies.

Just to summarise; the new law states that from 11 March 2015 radio microphones are not permitted to operate in the 698-806 MHz frequency range. The current free user license for UHF radio mics is now between 502-606 MHz and 622-698MHz. The band from 606-622Mhz has been allocated to Maori and is also not to be used. See the Govt document here for more details. In addition to those frequencies radio mics can operate on the 2.4Ghz range which is shared by wi-fi devices, more on that later.


All radio mics should have a sticker on them to say the frequency range they are operating on. If yours does not fall within those new frequencies we highly advise that you do not use it or else you could find yourself falling foul of the Radio Spectrum inspectors and getting a fine. It may be possible for your system to be tuned to the new legal frequencies, but if not then your only option is to purchase a new legal set. If you can’t work out what the frequency of your system is, or if it can be re-tuned then please contact us as we have a vast experience in wireless systems and are more than happy to help.


So when choosing a new radio mic there are several options for you. You can go the traditional UHF way in the new frequency bands above, which may involve slotting between your local DTV channels if you go for the lower 502-606 MHz, or you can go for the 2.4Ghz range which shares space with wi-fi devices, cordless phones etc. We would only advise the 2.4Ghz range for up to 2 devices due to the possibility of overcrowding from other users within your local area. However the great price we’re currently running on the Sennheiser D1 2.4Ghz digital systems does make it a very good option if you only want to run 1 or 2 sets. The advantages of this system is it’s extremely easy to set up and operate, and having Automatic Frequency Management means it continuously scans for interference and will change frequency to the best available one without you even being aware! It’s also got a few other cool features like 7 band graphic eq, audio effects and a de-esser.


For those of you wanting to run more than 2 wireless systems simultaneously we suggest you contact us with your exact requirement so we can design you the best system for your location as there are lots of variables to be taken into account to get a reliably operating system. We are also experts in fault finding problems you may be having with your existing system. You’d be surprised how things like some of the cheaper Chinese LED lights and HDMI cables can cause major problems with radio mics.
