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., 15V @ 15 mA
max. and 48 V @ 4 mA max., plus
