GatesAir has transitioned long-time customer MediaWorks to an uncompressed Audio over IP networking architecture.
The new transport solution keeps all signals in the digital domain and streamlines signal delivery, at once improving audio quality, reducing system complexity, and lowering the costs of live distribution linking across a single-frequency FM radio network (SFN).
Specifically upgrading the transport infrastructure of MediaWorks Radio’s iconic commercial brand, The Sound, the project refines and enhances the delivery of program audio from its studio in Ponsonby, Auckland, to synchronous transmitters on 93.8MHz FM at Auckland’s Sky Tower and Mount Ruru in the Waikato region.
The complete solution leverages Intraplex IP Link MPXp codecs with built-in SynchroCast technology to transport FM baseband and manage local ad insertions across its single-frequency transmission network (SFN), with Flexiva FAX50 exciters to support FM radio signal generation at each transmission site.
The modernised design eliminates the need to transport program audio to a separate studio for local ad insertions.
Transmission Manager for MediaWorks New Zealand, Ray Smith, says “By leveraging AES192, we can maintain high-end digital audio quality throughout the entire chain all the way to the exciter.
“Uncompressed MPX over IP transport ensures that the transmitters can be fully modulated without any decibel overshoot generated by compression algorithms. The average audio levels are higher, which means the transmitted signal offers the best possible audio quality that FM radio can offer.”
