Pilot tone:
25 to 32 kHz
Frequency stability:
± 0.002%
Spurious radiation:
Compliant with ETSI EN 300 422-1
Equivalent input noise:
–125 dBV, A-weighted
Input level:
If set for dynamic mic:
0.5 mV to 50 mV before limiting
Greater than 1 V with limiting
If set for electret lavaliere mic:
1.7 uA to 170 uA before limiting
Greater than 5000 uA (5 mA) with limiting
Line level input:
17 mV to 1.7 V before limiting
Greater than 50 V with limiting
Input impedance:
Dynamic mic:
300 Ohms
Electret lavaliere:
Input is virtual ground with servo adjusted
constant current bias
Line level:
2.7 k ohms
Input limiter:
Soft limiter, 30 dB range
Bias voltages:
Fixed 5 V at up to 5 mA
Selectable 2 V or 4 V servo bias for any electret
lavaliere
Gain control range:
44 dB; panel mounted membrane switches
Modulation indicators:
Dual bicolor LEDs indicate modulation
–20, -10, 0, +10 dB referenced to full modulation
Controls:
Control panel w/ LCD and 4 membrane switches
Low frequency roll-off:
Adjustable from 35 to 150 Hz
Audio Frequency Response:
35 Hz to 20 kHz, +/-1 dB
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)
