Specifications and Features
Audio Performance (overall system): (These specs apply to 400 Series mode only.)
Frequency Response: 32 Hz to 20 kHz (+/- 1dB)
THD: 0.2% (typical)
Signal to Noise Ratio (dB):
(overall system, 400 Series mode)
SmartNR No Limiting w/Limiting
OFF 103.5 108.0
NORMAL 107.0
111.5
FULL 108.5 113.0
Note: The dual envelope “soft”
limiter provides exceptionally 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
Total Harmonic Distortion:
0.2% typical (400 Series mode)
Input Dynamic Range: 125 dB (with full Tx limiting)
Rear Panel Controls and features: XLR audio output jack;
