Description
TRedess Fourth Series Medium Power is a family of Air-Cooled UHF and VHF Transmitters, Translators/Transposers and Gap-Fillers up to 5 kW (DTT and DAB+), bringing together maximum flexibility, high efficiency based on the use of the latest Ultra-Wide Band Doherty technology (UWBD), compact design, reliability and very smart installation and operation, fully oriented to minimize rack space and total cost of ownership.
TRedess Fourth Series Medium Power covers DVB-T, DVB-T2, ISDB-T, ISDB-Tb, ATSC 1.0 and ATSC 3.0 standards, for both MFN and SFN networks.
The units are very compact and modular, with several built-in options that can be useful for optimizing costs and space usage in multiple scenarios, like the built in GNSS receiver, built-in Satellite receiver with CAM (DVB-S/S2), built in Terrestrial input (DVB-T/T2) for retransmitters and the built-in Remux functionality (for ISDB-T). Fourth Series units include the complete local and remote control plus the Dual drive and 1+1 / N+1 redundant functionalities for increasing the system reliability.
Thanks to the latest Ultra-Wide-Band Doherty technology (booth Symmetric and Asymmetric Doherty) important cost reductions in energy consumption can be achieved without impacting in a truly smart operation and maintenance.
