Series: Trasmettitori TV Dual Cast
up to 650W rms
L-VISION Series represents the state of the art of the worldwide TV transmitter technology. In a compact solution only 3 RU, it covers a power range up to 650Wrms / 1200W p.s. and supports DVB-T/H / T2, ISDB-T/Tb, DAB/DAB+/T-DMB, ATSC, PAL and NTSC modulations. Of course, Dual Cast analog and digital configuration is also supported.
The design of the current TV transmitters has significantly contributed to the reduction of the lifetime costs of a broadcast network. The new digital transmitters feature perfect efficiency, outstanding design and flexible configurations for TV broadcasting. VISION Model represents the state of the worldwide TV transmitter technology.
TEM TV transmitters, based on Doherty Technology, are rated for a power level of 600 to 800 Wms hence providing high quality and grade performance for all available digital terrestrial TV Standards, e.g. DVB-T2, DVB-T/H, DTMB, ISDB-T and for analog TV.
New amplifiers that use Doherty technology have efficiency of 42% hence optimizing the use of energy and minimizing power consumption. Doherty technology has become wideband meaning its applicable to the whole UHF band. No modifications in the amplifier are required when an operator needs to change a certain channel.
TEM produces quality TV transmitters. The company is well experienced and known internationally.
TV Transmitters based on Doherty technology are of high efficiency, high reliability, reduced electricity consumption, therefore, less operating costs. The system set up is now fast and possible thanks to Doherty technology.
