RDS 4500


PRODOTTOSCHEDADOWNLOAD

RDS 4500, coder RDS programmabile, sia da locale che da remoto.
Il segnale Radio Data System permette di comunicare dati al ricevitore FM, senza interferire con il contributo audio.

Lo sviluppo di questo sistema consente la programmazione anche da satellite, con la possibilità di selezionare la singola unità di una rete complessa, mediante un semplice indirizzamento della stessa; RDS 4500 è un apparato professionale, progettato e costruito per soddisfare le più moderne esigenze degli operatori.

L’interfaccia da PC rende estremamente semplice ed intuitivo settare i parametri desiderati, consentendo sia il salvataggio che il caricamento di tutta l’impostazione in un solo passaggio.
