The television transmitters in this series are available in different versions for the VHF I, VHF III and UHF frequency bands and in different configurations that permit their installation and operation in sites with different characteristics and environmental conditions.

The exciters used, which are available in different televisionstandards and with a broad range of options may be single or doublewith automatic switch-over.
The final amplifier consists of distinct amplifiers operatingautonomously and combined in such a way as to guarantee full redundancyof the stages.

Each individual amplifier is, in turn, internally redundant and poweredindependently in order to ensure high reliability and practicality inmaintenance operations.

Microprocessor circuits carry out continuous control checks and providefor the visualization of all the operating parameters of the equipmenton an LCD display as well as transmitting them to rear-mountedconnectors for remote interfacing.

By replacing the analogue exciter with an equivalent DBT or DTT seriesexciter, the same unit can be used for the transmission of digitalsignals subject to an extremely limited de-rating thanks to the highdegree of linearity and the oversizing of the amplifiers. The great efficiency of the power supply circuits guarantees low powerconsumption and a high degree of MTBF.
