Sigmacom Broadcast EtherMPX NG | MPX over IP STL , Studio to Transmitter link/ Audio link.


EtherMPX is an IP STL system designed to transport real time MPX with RDS or L/R signal from studio to transmitter, through TCP/IP network. An affordable direct replacement of your analog STL, with higher performance!
Professional IP STLs must deliver uncompromised quality, no modulation overshoots, no audible latency for live on- air monitoring and time accuracy for SFN operation. Should be made of high reliability and dedicated hardware, unlike ordinary computer systems, and specifically designed to operate in harsh environment like the mountains where the transmitters are located.
EtherMPX is an IP STL designed exactly with these principles. It has the advantage to transparently transport Analog or Digital MPX with 2.5mS latency, and Analog or Digital L/R discrete channels over uncompressed linear PCM 24bit 48kHz (L/R mode) or 24bit 192kHz (MPX mode). State-of-the-art components for the analog section provide high end quality, with DC coupled inputs & outputs.
With EtherMPX and the flexibility of IP transmission, you can now make complex configurations that could never be imagined with traditional STLs. Feed unlimited number of EtherMPX decoders with only one encoder operating in multicast mode. Synchronize all your transmitters with the SFN option of EtherMPX, without the need for GPS receivers and antennas deployment


Key Facts


  •  Broadcast quality, real time, uncompressed linear PCM codec
  •  Dedicated hardware - no computer inside or other kid toys
  •  Transparent, MPX-HD transmission - no MPX destruction and recreation
  •  Support for Digital MPX (MPX over AES3) and MPX over AES67
  •  Adjustable bit rates, down to 1.1Mbps for MPX
  •  Can be used with high quality 802.11a/n Ethernet links
  •  Very low audio latency: down to 2,5mS in MPX mode
  •  DC coupled analog balanced inputs / outputs for minimal overshooting
  •  Unicast (1-on-1) or Multicast (1-to-Unlimited) transmission modes to feed unlimited number of decoders
  •  Maintenance free, 24/7 reliable operation in harsh environments – like TX sites are
