Medium Wave SD line

MEDIUM WAVE TRANSMITTERS -  SD LINE

This generation of medium wave totally solid state broadcasting transmitters offers enhanced overall efficiency and exceptional audio performance thus giving broadcasters superior value and performance while emphasizing long-term reliability.
Their modular design enables easy on-air maintenance without a loss in quality.
The transmitter incorporates multiple protection systems which prevent failures due to atmospheric and man-made transient sources.
    
As all of RIZ transmitters, the SD Line of solid state transmitters provides operating and maintenance personnel with maximum safety in compliance with IEC60215 safety standards applicable to radio broadcasting equipment.

MAIN FEATURES:

  • Frequency agility
  • Dual Exciter Section
  • Hot-swappable power modules
  • High overall efficiency
  • FM like audio performances
  • Microprocessor, DSP and EPLD technology
  • Remote controllable for unattended operation
  • Digital broadcasting compatibility (DRM)
  • Simple and cost-effective maintenance
  • Mobile or stationary versions available

 

All SD transmitters are operational in the ambient temperature range 1 – 45 °C  (1 – 50 °C) without influencing or changing  the transmitters characteristics.
