FMC01 - FM MPX Codec (MPX over E1/IP)

MPX over E1 / MPX over IP

Sync FM - FM SFN Network


Reduce your costs:
Connect your FM transmitter sites directly to your studio via MPX over E1 or via MPX over IP.

Save devices:
Integrate only one Stereo Generator and one RDS Encoder for these transmitter sites directly into your studio.

Direct Advantages

  • cost savings in purchasing because less equipment is needed (no stereo-generator or RDS Encoder needed anymore at the FM-TX sites)
  • production of the program and forwarding the FM MPX signal from one central location ( Play-Out Center of the Broadcaster )
  • eliminates costly processing of the modulation signal for every program at every single site
  • cost savings because of less power consumption - year by year
  • cost savings in infrastructure because of less space needed at the sites
  • cost savings in cooling down the sites - less equipment less heat dissipation necessary
  • cost savings due to short wiring
  • clearly arranged equipment, easily expandable
  • less equipment, safer operation, less maintenance
