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)
