Tieline MPX I and MPX II FM-MPX IP Codecs

Description

Tieline’s MPX I and MPX II are FM multiplex IP codecs for transporting composite FM signals to transmitter sites. The page focuses on real-time distribution of FM-MPX and MicroMPX signals, with support for return monitoring.

The product information describes single- and dual-channel composite encode and decode workflows, along with analog MPX, AES192, and optional satellite reception support. It also notes multicast and multi-unicast distribution, redundant streaming, RIST, FEC, and remote control and monitoring features.

The codecs are presented as tools for moving transmission-ready FM composite signals from the studio to the transmitter. The page also references support for centralized audio processing and RDS insertion at the studio, which can reduce equipment needs at transmitter sites.

Technical details on the page include dual Ethernet ports, internal power supplies, GPIO support, and compatibility with several broadcast networking and audio standards. The content is clearly aimed at radio engineers and broadcast transmission workflows.
