Model Details

PERFORMANCE
Specifications for measurements from analog left/right input to stereo composite output and to analog left/right output. Frequency Response (all structures, measured below gain reduction and clipping thresholds, high-pass filter off): Follows standard 50 microseconds or 75 microseconds pre-emphasis curve +/- 0.20dB, 5Hz-15kHz. Analog left/right output and 8200D/SRC digital output can be user configured for flat or pre-emphasized output. 8200D/32 output follows selected pre-emphasis curve.

Noise: Output noise floor will depend upon how much gain the processor is set for (LIMIT DRIVE, AGC DRIVE, TWO-BAND DRIVE, and/or MULTI-BAND DRIVE), gating level, equalization, noise reduction, etc. It is primarily governed by the dynamic range of the A/D Converter, which has a specified overload-to-noise ratio of 97dB. The dynamic range of the digital signal processing is 144dB. Total System Distortion (de-emphasized,100% modulation): <0.01% THD, 20Hz-1kHz, rising to <0.05% at 15kHz. <0.02% SMPTE IM Distortion.
Total System Separation: >65dB, 20Hz-15kHz; 70dB typical.
Polarity (PROTECTION, TWO-BAND PURIST, or BYPASS structure): Absolute polarity maintained. Positive-going signal on input will result in positive-going signal on output.

CIT25 Composite Isolation Transformer (optional)
Ground loops are a problem in some transmitter plants. A ground loop among OPTIMOD-FM and one or more exciters may occur, causing an increase in hum and noise. This is especially likely when OPTIMOD-FM is installed some distance from the exciter. The Composite Isolation Transformer provides the solution. Designed to be installed adjacent to each exciter, it provides ground loop isolation between the OPTIMOD-FM composite output and the exciter, and presents OPTIMOD-FM with a balanced floating load.
