2-channel FM-MPX over IP decoder with integrated satellite tuner


Professional two-channel FM-MPX (composite) over IP decoder with integrated satellite tuner


The MPX-2ds is an MPX decoder using IP-based network technologies for real-time distribution of complete FM-MPX ( FM composite signal) to connect your signal generation in the studio directly to the transmitter site via satellite or IP. Based on the know-how of the 2wcom FMC01, many satellite products of the 2wcom and customer requirements the MPX-2ds offers you a variety of features and opportunities to ease your daily work.


Flexible in application: The decoder is designed for broadcasters with professional requirements to the signal quality, optimized for distribution over satellite to a large number of receivers, and the time accurate playout on every single decoder. The MPX-2ds has always analogue and digital interfaces and the bandwidth can be reduced by using µMPX Technology. Furthermore, the RDS signal of the MPX can be filtered off and replaced by a local RDS signal generated by the internal full-featured RDS encoder.

Easy Operation: The MPX-2ds saves the high-quality IP lines to every transmitter site by using satellite for the distribution. The sound processing (stereo generation) and RDS generation on the transmitter site is moving towards the studio /playout center and this saves capex, service and support.

Saving bandwidth: A full FM-MPX signal needs approx. 3.5 Mbyte IP data capacity. While µMPX can operate on 320 kByte with only a low reduction of the quality.

Pay as you grow: All soft- and hardware components are individually combinable. Please ask for more details.

Transmission robustness: Dual Streaming and Pro-MPEG FEC ensure rock-solid IP transmission or you go beyond with SRT (secure reliable transport). The optional two hot pluggable power supplies guaranteeing fail-safe operation perfect the whole concept.

Smart management: Configuration set-up via an easy to use web interface for general settings as well as for backup or fall back. For remote control, the codec offers various possibilities – HTTP, FTP, Telnet, NMS, SNMP. Perfect synchronization can be achieved by PTPv2 and latency control.
