RDS Menu
The RDS control section of Omnia.9 contains the Main RDS menu, fields for Program Service (PS) and
Radio Text (RT) information, program identification fields, selectable dynamic Program Type (PTY),
selectable flags, and a section for selecting alternative frequencies.
RDS Main Menu
The Main Menu controls allow you to enable RDS, choose in which mode it operates, and set the
injection level.
The Injection Level slider sets the amount of RDS injection from 0 – 15%. The default
setting is 4%.
The RDS Mode drop-­‐down menu allows you to choose from several different RDS options.
o
When set to Off 56kHz, RDS is turned completely off and the audio extends all the
way out to 56kHz. In this mode, it is not possible to use an external RDS encoder,
even one installed after Omnia.9, as the audio occupies the portion of the
bandwidth normally reserved for RDS.
o
When set to Off 54kHz, the audio extends only to 54kHz to allow room for RDS data
provided by an external RDS encoder located after Omnia.9.
o
In the Internal mode, Omnia.9’s built-­‐in RDS encoder is active. Because RDS is
taken into consideration by the composite clipper, there is no loss of loudness with
this mode. Therefore, we highly recommend using the Internal mode whenever
possible.
o
The External Input 1, External Input 2, and External Input 1+2 modes determine
which of Omnia.9’s MPX inputs are active for RDS input when using an external
encoder.
The MPX 2 Output Mode drop-­‐down menu allows you to determine whether Omnia.9’s
MPX 2 Output will feed the full MPX signal, the 19kHz pilot extracted from the MPX signal,
or a unique and separately generated 19kHz pilot signal.
