A collaboration by
Omnia and Nautel, announced at the NAB Show Monday, is intended to improve the
quality of FM air chains.
The Omnia Direct digital
composite interface will be available in the Omnia.11 processor and
Nautel NV series transmitters. It was announced by Telos Alliance CEO Frank
Foti and Nautel President/CEO Peter Conlon.
to a summary by Omnia, “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.”
allows an AES-EBU cable between the Omnia.11 and the Nautel NV Series
transmitter to carry 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.”
Foti called it the digital
equivalent of the analog BNC-to-BNC composite connection, taking the output of
the audio processor stereo generator and coupling it directly to the modulator
of the exciter.
Omnia Direct functionality is available
on Nautel NV series transmitters from 3.5 kW to 44 kW. New transmitters are
shipping with the feature as standard; older NV series transmitters may be
upgraded with the NV software release 4.0, due shortly.
