Single Amplifier Onepower Transmitters and Transposers

Television Transmitters and Transposers

OnePower Series

OnePower is the most outstanding last engineering achievement from ONEtastic. In a compact 3+1U Rack, and with 2 power supplies OnePower delivers up to 2500 W rms of high efficiency digital output power or up to 4000 W p.s. when operating with analogue signals.

The system is composed by 1 or 2 OneDriver exciter/s (1RU) and an RF amplifier (2 or 3 RU), which makes a DVB-T/H/T2, ISDB-T/Tb, DAB/DAB+/T-DMB, ATSC, PAL or NTSC complete transmitter with native adaptive pre-correction circuits, built in GPS / GLONASS receiver for accurate synchronization and SFN operations, and multiple input interfaces (Satellite Receiver, ASI, ETI, EDI, Gigabit Ethernet or RF) so to be configured as Terrestrial or Satellite fed transmitter or even transposer.

OnePower final stage embeds 2 hot swappable power supply units, as well as a built in ASI and RF matrix, so 2 OneDriver can be connected to it to ensure a maximum level of redundancy and avoid the use of an additional external switch over unit.

Main features:

  • Compact 3+1U (or 3+2 in dual driver configuration) 19” Rack chassis
  • Output power up to 1600W rms (COFDM), up to 2500W rms (ATSC) or up to 4000W p.s. (analogue)
  • High efficiency broadband or wideband amplifier technology both in UHF and VHF bands
  • Built in ASI/RF matrix for automatic switch over, without the need of using an external switch over unit
  • DVB-T/H/T2, ISDB-T/Tb, DAB/DAB+/T-DMB, ATSC, PAL, NTSC, NICAM modulations fully supported
  • Embedded Re-Multiplexer/Layer Combiner/TS to BTS (188 to 204 byte) converter for ISDB-Tb
  • Adaptive pre-correction circuits
  • On-board high stability GPS / GLONASS receiver with battery
  • Flexible input interfaces:
    • 4 x ASI inputs (TS, BTS, T2MI, SMPTE-310M) + Analog input
    • 2 x ASI inputs and 2 x Gigabit Ethernet
    • 4 x ETI or 2 x ETI + 2 x EDI inputs
    • 1 x DVB-S/S2 Satellite Receiver input
    • 1 x RF input
  • Easy connection to 1 or 2 OneDriver exciters
