The digital units in this series are available in all VHF and UHF frequency bands in ultra-compact versions with redundant amplifiers, and with single or double exciters in order to meet each individual need. The excellent quality of the modulators, the linearity of the finalstages and the technology applied to pre-correction circuits guaranteehigh-performance and efficiency in amplifiers both in standard DVB andATSC versions.

The integrated SFN interface permits operations in precision offsetconditions with frequency lock onto GPS signal and compensation ofnetwork delay. Each of the system's units includes power supply and independentprotection and control circuits to ensure substantial lastingreliability in addition to quick and easy maintenance.
A main control panel collects data from all system components andfurnishes operating parameters through a practical display, sendingthem to interfaces for remote monitoring, available for differentcommunication protocols.
