Tieline's New MPX II Codec Now Shipping

Tieline has announced that its new MPX II codec will ship from January 2024.

Tieline MPX codecs deliver composite FM multiplex (MPX) codec solutions for real-time network distribution of FM-MPX or compressed MicroMPX (µMPX) signals to transmitter sites. The MPX II can effortlessly transport two discrete composite FM-MPX signals from the studio to transmitters with return monitoring in real-time. The codec supports analog MPX on BNC, MPX over AES192, and multipoint signal distribution, to deliver a wide range of flexible composite encoder and decoder solutions for unique applications.

"The MPX II streamlines FM radio broadcasting by allowing broadcasters to maintain baseband audio processing and RDS data insertion at the studio," said Charlie Gawley, VP Sales APAC & EMEA. "This slashes capital and operational costs by eliminating equipment from transmitter sites. And support for both analog and digital composite MPX signals allows broadcasters to transition from analog to digital exciters over time and maximize the value of their MPX investment."

The MPX II supports sending the full uncompressed FM signal, or high quality compressed µMPX at significantly lower bit-rates. An optional satellite tuner card with MPEG-TS and MPE support can receive DVB-S or DVB-S2 signals.

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, FEC, and automated SD card file failover.
