Informação
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).
