Descrição: Limiter/Stereo Generator
Informações:

The Optimod 8000 FM Limiter/Stereo Generator is the result of a new and exclusive systems approach to the design of the FM audio processing chain. In combining three conventionally separate components, the limiter, the compressor, and the stereo generator. Bob Orban has engineered a single system which is capable of achieving both high loudness and extremely high audio quality simultaneously. These two goals are mutually exclusive in conventional systems. It is important that this manual be read carefully and that the instructions be followed conscientiously. Make no assumptions on the basis of past experience with conventional systems. A technical paper entitled "Combining High Signal Quality with High Modulation Levels in FM" has been included with this instruction manual. We suggest that you read this before proceeding with the actual installation and adjustment of your Optimod 8000.
