Information

It is impossible to define the listening quality of even the simplest limiter or compressor with the usual specifications because they cannot adequately describe the crucial dynamic processes which occur with program material. We evaluate these dynamic processes at the factory and control them to close tolerances. These measurements require special test fixtures, cannot be readily duplicated by measurements with standard test equipment in the field, and cannot be described in familiar terms. OPTIMOD-AM is the result of computer-aided design, high-precision components, careful testing, and extensive burn-in. When OPTIMOD-AM’s MODE switch is set to PROOF, clipping and gain reduction are defeated without bypassing any circuitry — unlike equipment produced by some other manufacturers. (A separate switch defeats Transmitter equalization.) Because of this, the following specifications truly reflect the accuracy and transparency of OPTIMOD-AM’s signal path. Performance Frequency response: ±1.0dB, 50-9500Hz (optional 5kHz filters defeated and MODE switch set to PROOF). Total harmonic distortion: <0.2% at 100% modulation, 50-9500Hz (MODE switch set to PROOF). RMS noise: >65dB below 100% modulation, 30-20,000Hz (MODE switch set to PROOF). Separation (9100B/2): >25dB, 50-5000Hz; >20dB, 5000-7500Hz; 30dB typical, 50-5000Hz (MODE switch set to PROOF). Stereo 9100B/2 units contain a subsystem designed to protect C-Quam receivers by limiting left or right channel negative peak modulation to -75% (where 100% = full negative envelope modulation) through asymmetrical clipping in left and right channels. Dynamic gain reduction in the L-R channel prior to this clipping prevents clipper overdrive by momentarily reducing separation when it is high. Such gain reduction is constrained to 6dB or less, as required by the program material. Mono receivers are unaffected and retain full loudness. The STEREO ENHANCE trimmer on Card #1S10 can increase L-R gain by up to 6dB. Dynamic separation is typically 30dB (with pink noise signal and MODE switch set to OPERATE).
