Channel Spacing: Selectable; 25 or 100 kHz
Frequency selection: Control panel mounted membrane switches

941: Selectable, 50 or 100 mW
Compatibility Modes: US: Nu Hybrid, Mode 3, IFB
X: Digital Hybrid Wireless™ (400 Series),
200 Series, 100 Series, Mode 3 , Mode 6, IFB
941: Nu Hybrid, IFB
Pilot tone: US: 3.5 kHz deviation (in Nu Hybrid Mode)
X: 25 to 32 kHz; 5 kHz deviation (in 400 Series Mode)
941: 27 to 32 kHz; 3 kHz deviation (in Nu Hybrid Mode)
Frequency stability: ± 0.002%
Spurious radiation: US: Compliant with ETSI EN 300 422-1 v1.4.2
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 of –20, -10, 0,
+10 dB referenced to full modulation.
Controls: Control panel with LCD and four 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):
(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)
SmartNR No Limiting w/Limiting
