INTRODUCTION ORBAN Model 6200
Reading this Manual
This manual supports both 6200 OPTIMOD-DAB and 6200S OPTIMOD digital audio
processors. In general, when text refers to 6200 OPTIMOD-DAB, the information also
applies to 6200S. Whenever there is a difference, it is noted. At the time of this writing,
6200S differs from 6200 in size and a few specifications (noted in Section 6), and has no
rear panel remote control interface connector.
6200 OPTIMOD-DAB Digital Audio Processor
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 exclu-
sive 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 broad-
cast 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 in-
creasing the average modulation of the channel substantially beyond that achievable by
“recording studio”-style compressors and limiters. Because such processing can exag-
gerate 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
