(100 kHz Steps)
(Frequency usage varies by country)
Frequency range: 256 frequencies in 100 kHz steps for one
25.5 MHz wide block
Channel Spacing: 100 kHz
Type of Modulation: FM
Frequency selection: Control panel mounted membrane switches
RF Power output: 50 mW (nominal)
Compatibility Modes (6) Digital Hybrid Wireless® (400 Series) and IFB
Pilot tone: 25 to 32 kHz; 3 kHz deviation in hybrid mode

Deviation: ± 50 kHz max. in hybrid mode
Spurious radiation: 60 dB below carrier
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

Audio Frequency Response: 35 Hz to 20 kHz, +/-1 dB (The low frequency
roll-off is adjustable - see graph above)
Signal to Noise Ratio (dB):
(overall system, 400 Series mode)
SmartNR No Limiting w/ Limiting
OFF 103.5 108.0
NORMAL 107.0 111.5
FULL 108.5 113.0
(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)
Total Harmonic Distortion: 0.2% typical (400 Series mode)
Audio Input Jack: Switchcraft 5-pin locking (TA5F)
Antenna: Flexible, unbreakable steel cable.
