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

0.2% typical (400 Series mode)

Input Dynamic Range:

125 dB (with full Tx limiting)
