Information

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.
