Information

OPTIMOD-FM is an integrated signal-processing system that replaces conventional compressors, limiters, and clippers. Each part of the OPTIMOD-FM system has been precisely engineered to be compatible with all other parts to ensure optimal performance. The 8101B is a basic OPTIMOD-FM Audio Processor, without a stereo coder (stereo generator). Various OPTIMOD-FM accessories (see page 1-5) can provide processing enhancements or additional operational convenience. The 8101B OPTIMOD-FM Audio Processor: • Rides gain over a range of as much as 25dB, compressing dynamic range and compensating for gain riding errors on the part of operators. The amount of dynamic range reduction ordinarily produced is adjustable. • Makes gain riding and compression virtually undetectable (if operated at optimal release time setting) by use of advanced, program-controlled time-constants and multiband compression. • Prevents aliasing distortion by providing bandwidth-limiting 15kHz low-pass filters ahead of the stereo coder. Since full overshoot compensation is provided for these filters, OPTIMOD-FM provides extremely tight peak control. • Makes audio quality more consistent by correcting the balance between Bass and midrange material when OPTIMOD-FM’s dual-band compressor is operated in independent mode. When the compressor bands are fully coupled (“wideband” mode), OPTIMOD-FM preserves frequency balances and produces an output which sounds almost exactly like its input. • Prevents peak overload and overmodulation due to the effects of the FM pre-emphasis curve.
