GatesAir ‘Simplifies’ HD Radio Architecture


What GatesAir is calling “the industry’s first HD Radio Importer/Exporter solution” will get its formal introduction at the 2018 NAB Show in Las Vegas on April 9.

The move is part of GatesAir’s efforts to bring new innovations to its HD Radio product portfolio, and its fourth-generation Flexiva Importer/Exporter seeks to become a top solution for providing dynamic time and audio correction.

“Diversity Delay” is a big part of what the FMXi 4g can bring to radio.

Through what GatesAir says is an “exclusive algorithm,” the devices can ensure proper time alignment between analog and digital (HD Radio) signals by removing the objectionable blending artifacts.

As the digital signal transitions to analog and back, the lack of proper time alignment prevents program linearity for the listener due to an eight-second delay between the analog and digital broadcast.

HD Radio Diversity Delay was first only achievable through manual adjustments, and later through interoperability between modulation monitors and either exporters or audio processors. GatesAir worked to eliminate all manual and external device needs to enable time alignment by integrating specialized Diversity Delay software inside the FMXi 4g.

“The software intelligence built into the FMXi 4g aligns the time, levels and phase of the audio to remove undesirable artifacts and deliver a clean and engaging audience experience,” says GatesAir Chief Product Officer Rich Redmond. “We believe that this will prove valuable not only to broadcasters that deliver from a single transmitter, but also for single-frequency networks that have multiple, overlapping transmitters delivering precision-timed HD Radio content across larger markets and terrain-challenged regions.”


GatesAir will introduce the FMXi 4g and other new HD Radio enhancements for audio and data transport at the 2018 NAB Show (Las Vegas Convention Center, Booth N3703).
