The OPTIMOD 8585 Digital Audio Processor
Orban’s all-digital Optimod-Surround 8585 Audio Processor
can help you achieve the highest possible quality digital
audio broadcast, digital television, and netcast audio
processing using up to 7.1 audio channels. Thanks to
versatile compression ratio controls and a mastering-quality
look-ahead peak limiter, the 8585 is also ideal for
mastering chores.
OPTIMOD 8585 is descended from the industry-standard OPTIMOD
audio processors for radio and television. Thousands of
these broadcast-specific processors are at-tracting and
holding audiences all over the world. They have proven that
the “OPTIMOD sound” can attract and keep an audience even in
the most competitive commercial environment.
Take a little time now to familiarize yourself with OPTIMOD
8585. A small investment of your time now will yield large
dividends in audio quality.
The rest of Chapter 1 explains how OPTIMOD 8585 fits into
the DAB and DTV broadcast facilities and how to use it for
netcasting. Chapter 2 explains how to install it.
Chapter 3 explains how to operate OPTIMOD 8585, Chapters 4
through 6 provide reference information.
OPTIMOD 8585 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 8585 unprocessed audio. No
other audio processing is necessary or desirable.
