DOLPHIN

è un codificatore RDS dinamico di facile uso che supporta tutte i servizi e le funzioni più diffuse.
Le caratteristiche tecniche e operative sono state accuratamente progettate per soddisfare le esigenze più avanzate in termini di programmazione e trasmissione RDS.

Basato su tecnologia DSP allo stato dell’arte,

DOLPHIN

garantisce la più pura qualità di modulazione.
La sua architettura, totalmente digitale, assicura inoltre una grande affidabilità nel tempo e un facile aggiornamento del firmware

Un potente software di controllo da Pc è fornito in dotazione. Esso consente il controllo, in modo semplice ed intuitivo, di tutti i dati RDS e dei parametri di generazione del segnale (livello e fase, sincronismi, ecc). La schermata base del software indica anche, con continuità, il testo dei messaggi PS e RT in onda, per un facile monitoraggio dell’emissione RDS anche in assenza di un sintonizzatore FM.
