Orban’s all-digital 6200 OPTIMOD-DAB Audio Processor can help you achieve the highest possible quality digital audio broadcast processing. Because all processing is performed by high-speed mathematical calculations within Motorola DSP56009 Digital Signal Processing chips, the processing has cleanliness, quality, and stability over time and temperature that is unmatched by analog processors. OPTIMOD-DAB is descended from the industry-standard OPTIMOD audio processors for radio and television. Thousands of these broadcast-specific processors are on the air all over the world. They have proven that the “OPTIMOD sound” can attract and keep an audience even in the most competitive commercial environment. Because OPTIMOD-DAB incorporates several audio processing innovations exclusive to Orban products, you should not assume that it can be operated in the same way as less sophisticated processors. If you do, you may get disappointing results. Take a little time now to familiarize yourself with OPTIMOD-DAB. A small investment of your time now will yield large dividends in audio quality. The rest of Chapter 1 explains how OPTIMOD-DAB fits into the DAB and DTV broadcast plants, or can be used for webcasting. Chapter 2 explains how to install it. Chapter 3 tells how to properly operate OPTIMOD-DAB. Chapter 4 through Chapter 6 provides reference information. OPTIMOD-DAB was designed to deliver a high quality sound while simultaneously increasing the average modulation of the channel substantially beyond that achievable by “recording studio”-style compressors and limiters. Because such processing can exaggerate flaws in the source material, it is very important that the source audio be as clean as possible. For best results, feed OPTIMOD-DAB unprocessed audio. No other audio processing is necessary or desirable. If you wish to place level protection prior to your studio/transmitter link (STL), use the Orban 8200ST OPTIMOD-Studio Compressor/Limiter/HF Limiter/Clipper. The 8200ST can be adjusted so that it substitutes for the broadband AGC circuitry in OPTIMOD- DAB, which is then defeated.
