Modulation indicators: Dual bicolor LEDs indicate modulation of
–20, -10, 0, +10 dB referenced to
full modulation.
Controls: Control panel with LCD and four membrane
switches.
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)
(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)
