OPTIMOD-PC is also an excellent mastering processor, offering soft knee multiband compression with knee and ratio controls available separately for each band. This is followed by a low-IM look-ahead limiter that can typically achieve 12 dB of gain re- duction before it produces objectionable artifacts—this limiter is exceptionally loud and clean.

    In digital radio applications, if you wish to place level protection prior to your stu- dio/transmitter link (STL), use an Orban studio AGC like the Orban 8200ST. The 8200ST can be adjusted so that it substitutes for the broadband AGC function in OPTIMOD-PC, which is then defeated.

    It is usually best to locate OPTIMOD-PC cards in the same machine that runs the en- coding software, like Orban OPTICODEC-PC, Microsoft Windows Media Encoder or Real Networks HELIX Producer. This is because the output of the encoder is at a much lower data rate than the audio used to drive the OPTIMOD-PC input(s), so it is less expensive to transport encoded audio than unencoded audio.

    1-33 OPTIMOD-PC INTRODUCTION Analog Telephone/Landline (PTT/Post Office Line) Analog landline quality is extremely variable, ranging from excellent to poor. (For- tunately, they are largely obsolete, having been replaced by digital links.) Whether landlines should be used or not depends upon the quality of the lines locally avail- able, and upon the availability of other alternatives.

  • Page 48: Optimod-Pc At The Transmitter: Gain Control Before The Stl

    Further, many STLs require level control to prevent the STL from being overloaded. To apply such level control and compression, we recommend an Orban AGC/Limiter/HF Limiter (like another OPTIMOD-PC or an Orban 6300 stand-alone multipurpose processor or an OPTIMOD-PC) before the STL transmitter.

If not psychoacoustically masked by the program material, this noise may be perceived as distortion, “gurgling,” phasiness, or other interference. Psycho- acoustic calculations are used to ensure that the added noise is masked by the de- sired program material and not heard.

    3-56 OPERATION ORBAN MODEL 1101 The Five-Band Structure The Five-Band structure consists of a stereo enhancer, a slow gain-riding two-band AGC, an equalization section, a five-band compressor, a dynamic single-ended noise reduction system, an output mixer (for the five bands), and a low-IM look-ahead lim- iter.

Hiss has most of its energy in band 5, while program material typically has less energy in this band, so the B5 D XPANDER control’s setting is critical to removing hiss while minimizing removal of desired pro- gram energy.

    (or worse from the broadcaster’s point of view, to mute a commercial). Whether measured via the CBS or BS.1770 algorithms, the CBS loudness controller algorithm in Orban’s current products effectively controls subjective loudness to much better than this +2, –5 dB window.
