SPECIFICATIONS
RF Carrier Frequency Range
782-806 MHz
Working Range
U1: 152.4 m (500 ft) minimum, under typical conditions; 487.6 m (1600 ft ) line of
sight
U1H: 300 m (1000 ft.) minimum, under typical conditions; 975.2 m (3200 ft) line of
sight
NOTE: Actual working range depends on RF signal absorption, reflection and inter-
ference
Audio Frequency Response
50 to 15,000 Hz, ±2 dB. NOTE: Overall system frequency response depends on the
microphone element
Gain Adjustment Range
U1, U1H: 0 to 40 dB
U2: 0 to 26 dB
Modulation
±45 kHz deviation compressor-expander system with pre-and de-emphasis
RF Power Output
U1, U2: 10 mW maximum
U1H: 100 mW maximum
Dynamic Range
>102 dB, A-weighted
RF Sensitivity
Image Rejection
90 dB typical
Spurious Rejection
75 dB typical
Ultimate Quieting (ref. 45 kHz deviation)
>100 dB, A-weighted
Audio Polarity
Positive pressure on microphone diaphragm (or positive voltage applied to tip of
WA302 phone plug) produces positive voltage on pin 2 with respect to pin 3 of low
impedance output and the tip of the high impedance 1/4-inch output
System Distortion (ref. ±45 kHz deviation, 1 kHz modulation)
0.3% Total Harmonic Distortion typical
Power Requirements
U1, U1A, U2: 1.5V AA alkaline battery; Nicad optional
U4: 90 to 230 Vac, 50/60 Hz
Power Consumption
U4S: 9.6 W min., 13.2 W max.
U4D: 12 W min.,16 W max.
UA840: 15 W min., 16 W max.
