Low frequency roll-off: Selectable; -3dB at 35, 50 or 70 Hz.
Audio Frequency Response: 35 Hz to 20 kHz, +/-1 dB (The low
frequency roll-off is adjustable)
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
The dual envelope “soft”
limiter provides exceptionally
good handling of transients
using variable attack and release
time constants. The limiter reduces 30
dB of dynamic range into 4.5 dB, which
reduces the measured figure for SNR
without limiting by 4.5 dB.
Total Harmonic Distortion: 0.2% typical (400 Series mode)
Audio Input Jack: 3-pin Female XLR
Phantom Power: • 5V @ 18 mA max.
