Audio Frequency Response:
Signal to Noise Ratio (dB):
(overall system, 400 Series mode)
(Note: the dual envelope "soft"
limiter provides exceptionally
good handling of transients
using variable attack and release
time constants. The gradual onset of limiting in the design begins below full
modulation, which reduces the measured figure for SNR without limiting by
4.5 dB)
