WIRELESS MICROPHONES - STATE OF THE ART AND PERSPECTIVES: THE Michelangelo Carrozzo'S OPINION at the AES Conference 2019
Michelangelo Carrozzo's opinion at the official AES Conference in MIR 2019 Edition.
Rimini, 7th May 2019 - On the occasion of 2019 MIR Rimini, the renowned Italian show for the professional audio industry, Michelangelo Carrozzo, R&D Director of the dBTechnologies Wireless Department, attended the AES (audio engineering society)* Conference, a professional event organized by the international organization now leader in the promotion of training and educational events dedicated to specialists in the field of audio and sound engineering.
As an official speaker, Carrozzo focused on the theme of the Wireless Stage Coordinator, a new professional figure emerging in the panorama of high resonance live events, which is born to respond to the need of a precise radio microphone coordination on stage. "In the professional field and all over the world," explains Michelangelo Carrozzo, "the frequencies used by radio microphones and in-ear monitors are between 470 MHz and 950 MHz; these frequencies are shared with digital TV broadcasters and mobile phones in all countries worldwide; for this reason the coordination of multiple radio microphones and in-ear monitors on stage requires more and more knowledge and experience. Thanks to the application of a basic methodology supported by the experience in selecting the most suitable wireless systems, it is possible to greatly improve the reliability of systems on stage, even in the case of a large number of systems and a synchronous multi-use of different systems.
Further information and novelties come from the world of digital wireless microphones and usable frequencies: currently various and important manufacturers are directing research and technological development to a new generations of digital radio microphones; the market offers relatively economical systems operating in the 2.4 GHz band and other less economical systems operating at 470 - 790 MHz.
What are the differences between the two types?
"Since radio microphones have to coexist with other sources of interference such as digital TV broadcasters and mobile phones, the new generation need to be reliable even in the presence of strong interference, which cannot always be avoided. There are some important aspects, advantages and disadvantages in the choice between the two types 2.4 GHz and 470-790 MHz and these characteristics are important to know before investing in the purchase of wireless systems," explains and concludes Mr. Carrozzo.
*The Audio Engineering Society is the only professional society devoted exclusively to audio technology. Founded in the United States in 1948, the AES has grown to become an international organization that unites audio engineers, creative artists, scientists and students worldwide by promoting advances in audio and disseminating new knowledge and research.Currently, over 12,000 members are affiliated with more than 75 AES professional sections and more than 95 AES student sections around the world. Section activities may include guest speakers, technical tours, demonstrations and social functions. Through local AES section events, members experience valuable opportunities for professional networking and personal growth.
