Nautel GV² hosts complete HD Radio air chain

Nautel’s new GV² Series transmitters integrate all HD Radio components inside the transmitter hardware.

According to the company, the update to its FM transmitter series provide the full hardware platform to support HD Radio with Xperi Gen4 Importer, Exporter and Exgine implementations for HD radio encoding, station logo and artist experience.  In addition, Omnia for Nautel covers FM and HD Radio audio processing needs and provides Livewire AoIP inputs for all audio streams.

“As long as there is an IP Audio feed available at the transmitter site, operation is Audio In and RF out,” said Philipp Schmid, Nautel CTO. “FM stations currently operating digital modes or considering a shift to HD Radio will benefit from this deployment as well as elimination of time alignment issues.”

GV² natively incorporates its software-based radio air chain architecture. A key component is an air chain selector which allows GV² to select one of many air chain inputs (FM and all HD) and change from one feed to another; no matter whether the feed originates from the studio, the cloud or the internal platform, FM/HD1 time alignment is guaranteed through the blend lock function without the need of GPS antenna connections.

“Nautel led the industry with the first embedded exporter over a decade ago, then with the first combined and software implemented Importer/Exporter, and more recently with research to perfectly time lock the FM and HD signals to eliminate blend drift. Now the GV² continues that evolution by bringing all functionality and even audio processing into the transmitter, said Schmid.”
