  • Overall efficiency better than 70%.
  • Hot-pluggable and broadband power amplifier modules.
  • Each module features switching mode power supply to control and stabilize power supply voltage.
  • Each amplifier module provides Automatic Power Control.
  • Suitable for mono & stereo broadcast operations.
  • Protection against high VSWR, overdrive, overcurrent and overtemperature.
  • Compliance to IEC safety standards.
  • Compliance to ETSI – CCIR – FCC standards.
  • Entire transmitter can be switched off through an emergency button.
  • High redundancy guaranteed by 10 power modules of 2.2 kW RF power.
  • All measurement and working parameters are displayed on front panel.
  • Remotely controllable by telemetry system.
  • Design for 24/7 non-stop operation.
  • The transmitter include an integrated system for automatic and manual switching between two exciters.
  • In Automatic mode the changeover is activated when active power of exciter falls below 3dB.
