“Long range” wireless audio conference system

This product allows conference-type communication between 2 to 6 users over 1 km (no limit for the number of receivers).

Beside its low weight (150 g) and its compact design (only 120 x 60 x 22 mm), the main innovation of this system is the "open microphone" communication concept : it allows every users to talk whenever they want, without waiting for their turn and without needing some accessory for starting talking (push-to-talk button, Vox system...)
Moreover, a very good level of audio quality is maintained in any environment (stadium, building site, road works, urban area…) thanks to a dedicated digital filter, which reduces any disturbing noise.

Developed in 2005 according to the specifications of the LFP and of the French Referees Committee, it has been used since July 2005 in the French 1st and 2nd leagues and by the world best referees of football and rugby.

More generally, you can use this system for any application that requires long-range wireless audio communication.
Beside any sports context, this product has also proved to be useful for the scene, rescue services, restaurants and construction.
