Audio Performance

• Frequency Response     90 Hz to 20 kHz (+/-1 dB)
• Low Frequency Roll-Off -12 dB/octave, 70 Hz
• THD       0.2% (typical)
• SNR at Receiver Output SmartNR: Off 103.5 (no limiting) 108.0 (with limiting)
• Normal: 107.0 (no limiting) 111.5 (with limiting)
• Full: 108.5 (no limiting) 113.0 (with limiting)

Note: The dual envelope "soft" limiter provides good handling of transients using variable attack and release time constants. Once activated, the limiter compresses 30+ dB of transmitter input range into 4.5 dB of receiver output range, thus reducing the measured figure for SNR without limiting by 4.5 dB
