Abstract

L'invention concerne un émetteur sans fil (1), formant partie par exemple d'un microphone sans fil. Cet émetteur présente une entrée audio (T9). La bande de fréquences, qui doit être utilisée localement, est programmée, par cette entrée audio et une unité de décodage audio (9) provenant d'une source de signaux audio (11, 13). Cette bande comprend une ou plusieurs fréquences porteuses pouvant être sélectionnées (fc) pour la transmission, lesquelles fréquences sont sélectionnées manuellement (8).
