Specifications

Performance

Specifications for measurements from analog left/right input to stereo composite output and

to analog left/right output are as follows:

Frequency Response (All structures, measured below gain reduction and clipping

thresholds, high-pass filter off): Follows standard 50µs or 75µs pre-emphasis curve

}0.20dB, 5Hz-15kHz. Analog left/right output can be user-configured for flat or pre-emphasized

output.

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 manufacturer-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 <.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.
