Tieline TLR6251 - MPX I Single Stream Professional FM-MPX IP Codec

Tieline’s MPX I and MPX II codecs deliver composite FM multiplex (MPX) codec solutions for real-time network distribution of FM-MPX or MicroMPX (μMPX, optional) signals to transmitter sites. The MPX I is ideal for transmitting a composite STL signal from a single station with return monitoring, whereas the Tieline MPX II can transport two discrete composite FM-MPX signals from the studio to transmitters with return monitoring.

Both the MPX I and MPX II support sending the full uncompressed FM signal, or compressed μMPX to deliver high-quality multiplexed FM signals at lower bit-rates. They support analog MPX (BNC) or MPX over AES192 to deliver a wide range of flexible composite encoder and decoder configurations for many different applications. Order an optional satellite tuner card at purchase to support decoding DVB-S or DVB-S2 signals.

Applications
Sending transmission-ready FM composite signals from the studio allows broadcasters to maintain audio processing and RDS data insertion at the studio. This significantly reduces capital and operational costs by eliminating processing equipment from transmitter sites, which reduces on-site power consumption, wiring and space requirements, as well as site visits for service and support. Composite MPX over IP signals can be easily replicated and distributed using multicast and multi-unicast technologies and take advantage of rock solid redundancy features like redundant streaming, RIST and FEC.

Single or Dual MPX Composite Encode or Decode: Encode/Decode up to two point-to-point MPX/μMPX composite signals.
MPX/μMPX Composite Encode or Decode with Encoder or Decoder FM Monitoring: Encode/Decode two point-to-point MPX/μMPX composite signals; at the encoder monitor the demodulated local MPX input or the return feed. At the decoder monitor the MPX output or the secondary MPX feed, which is either the local MPX input or the secondary stream.
