Description

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

Sigmacom started up in 1996, and we’ve been on a great ride ever since. From technical support to radio & TV stations across northern Greece, soon begun to design & manufacture FM exciters, power amplifiers, microwave links, antenna arrays and RF combiners. In 2010 we released the first FM DDS exciter in the world that accepts Digital MPX, and later in 2012 our first STL over IP with Digital MPX was on the air! Since then we have release multiple version from this populair EtherMPX link.
