GatesAir IX-IPL-ECN-UMPX Optional μMPX Encode

FM Composite Signal Transport Over IP Networks

The GatesAir IX-IPL-ECN-UMPX is an optional μMPX encode feature designed for GatesAir Intraplex IP Link 100e, 100c, and 100n codecs. It enables broadcasters to transmit a complete FM composite MPX signal—including baseband audio, stereo pilot, and RDS—over IP networks with exceptional accuracy. This solution is purpose-built for studio-to-transmitter links where preserving the integrity of the FM signal is critical.

Designed for Professional Broadcast Applications

This μMPX encoding option is engineered for radio broadcasters who need a reliable way to move full FM signals across modern IP infrastructure. By encoding the entire multiplex signal rather than separate audio components, the system ensures that modulation, stereo separation, and RDS data remain intact from studio to transmitter, making it ideal for professional STL and distribution workflows.

High Bitrate Encoding with Precise Signal Control

Operating at a high bitrate of up to 320 kbps, the IX-IPL-ECN-UMPX delivers outstanding audio quality with precise peak management. The encoding process maintains strict control over modulation levels, ensuring that the transmitted MPX signal arrives ready for direct decoding without introducing distortion, clipping, or timing inconsistencies.

Seamless Integration with Intraplex IP Link Codecs

This option is fully compatible with GatesAir Intraplex IP Link 100-series codecs, allowing it to be added to existing installations without changes to the core hardware platform. When paired with the corresponding μMPX decode feature at the transmitter site, broadcasters can achieve a clean, transparent end-to-end FM signal path over IP.

Optimized for Cost-Effective IP Transport

By transporting the FM composite signal over IP, broadcasters can reduce dependence on legacy STL infrastructure while maintaining broadcast-grade performance. The IX-IPL-ECN-UMPX supports efficient contribution and distribution over managed IP networks, leased lines, or private connections, offering flexibility without sacrificing signal quality.

Ideal for Modern FM Transmission Workflows

This μMPX encoding feature is well suited for FM radio stations transitioning to IP-based transport while maintaining strict technical standards. It supports applications ranging from studio-to-transmitter links to networked audio distribution, ensuring consistent FM performance across diverse broadcast environments.
