Wireless MicrophonesA wireless microphone, as the name implies, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. Wireless microphones are widely used in the entertainment industry, television broadcasting, and public speaking to allow public speakers, interviewers, performers, and entertainers to move about freely while using a microphone to amplify their voices. |
What is the 2012 Digital Switchover (DSO)?The analogue to digital TV switchover is Government policy. It will mean that almost everyone will be able to receive digital TV through an aerial. Digital TV uses less broadcast space which means that after switchover, there will be more room for new services such as wireless broadband, local TV and High Definition Television (HDTV).Why does it affect wireless microphone users?After the DSO the 800MHz band will no longer be used for TV broadcast. Ofcom is clearing the 800MHz band TV channels 61-69 to match spectrum being released in other European countries (European Harmonisation). This will benefit people across the UK because the spectrum will be able to be used for next-generation mobile broadband services.What does this mean?Certain models of wireless microphone will not work after 21 September 2011 due to the changes in available frequencies. New models of wireless microphone are available that operate on the new frequencies. Check that your microphone is marked as Channel 38 Ready or Future-Proof.For more information, visit the Shure 2012 Digital Switchover Resource Centre. All Shure wireless microphones sold on Rocking Rooster are future-proof, DSO-ready. |
