Nautel and Omnia have jointly created a system that digitally transfers the composite output of an audio processor directly to an FM broadcast transmitter.
NAB 2013, Booth C2207 — The long sought after goal of a fully digital transmission chain which doesn’t sacrifice loudness has now been realized due to collaboration between two of the industry’s leading organizations, Omnia and Nautel. The first result of that collaboration, the Omnia Direct [MPX over AES] fully digital composite interface, was demonstrated at NAB 2013 and will be initially available in the Omnia.11 and Nautel NV series transmitters.
“Nautel and Omnia continually strive to maximize the performance of their respective products,” said Peter Conlon, Nautel President and CEO. “As a result, both companies are recognized as bold innovators, constantly pushing the boundaries, even during these tough economic times. This exciting cooperation between our companies will benefit our customers by delivering the finest in sound quality to help them dominate the dial”.
In the past, stations concerned about maximum modulation needed to use an analog composite signal. This was primarily due to the required high sample rate of A/D converters used to create discrete left/right inputs to the digital exciter. With the Omnia Direct [MPX over AES] interface, a single AES-EBU cable between the Omnia 11 and the Nautel NV Series transmitter carries the baseband signal in digital form. This 100% digital path eliminates the noise and distortion of A/D converters and reduces potential overshoots, while ensuring full FCC mask compliance.
“With Omnia Direct, we finally have the digital equivalent of the analog BNC-to-BNC composite (mpx) connection, where we can take the output of the audio processor’s stereo generator and couple it directly to the modulator of the exciter. This enables the exciter to modulate, with precision, whatever the processor delivers,” said Frank Foti, Telos Alliance CEO and Omnia Audio founder.
Initially, the Omnia Direct [MPX over AES] functionality is available on Nautel NV series transmitters from 3.5kW to 44kW. New transmitters are shipping with the feature as standard, and older NV series transmitters may be upgraded with the NV software release 4.0 which is now in controlled introduction.
