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.
