La famille d’excitateurs SYNAPSE est un excitateur FM compact offrant de très bonnes performances à faible coût, conçue pour des applications économiques comme station de faible puissance ainsi que comme pilote pour les transmetteurs de faible et moyenne puissance. Il est réalisé dans les puissances de sortie de 30 W à 50 W et il est logé dans une armoire ultra-compacte d'une seule hauteur. SYNAPSE est également disponible en fréquences JPN et OIRT. Sa puissance de sortie peut être facilement réglée de 0 à la puissance nominale.

Pour optimiser au maximum le prix, le SYNAPSE est disponible en deux versions: MONO / MPX et STEREO. Le Stereo Coder peut être facilement mis à niveau sur le site même après la première installation.

SYNAPSE permet d’être facilement mis à niveau avec des options utiles, afin de répondre à tous les besoins du client, tels que le codeur RDS intégré sur site et le codage de station FCC.

La carte CPU intégrée au SYNAPSE permet un grand nombre de paramètres de surveillance. Un menu convivial visualisé sur un écran LCD clair permet la configuration et le réglage de tous les paramètres de fonctionnement et la surveillance des valeurs de fonctionnement.
