GENERAL
Frequency Range and Transmitter Output Level
NOTE: This Radio apparatus may be capable of operating on some frequencies not autho-
rized in your region. Please contact your national authority to obtain information on authorized
frequencies for wireless microphone products in your region.
Operating Range Under Typical Conditions
100m (300 ft.)
Note: actual range depends on RF signal absorption, reflection, and interference
Audio Frequency Response (+/– 2 dB)
Minimum: 45 Hz
Maximum: 15 kHz
Total Harmonic Distortion (ref. +/– 38 kHz deviation, 1 kHz tone)
0.5%, typical
Signal-to-Noise Ratio
>100 dB A-weighted
Operating Temperature Range
–18°C (0°F) to +50°C (+122°F)
Note: battery characteristics may limit this range
Transmitter 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.
Gain Adjustment Range
25 dB
Audio Input Level
-5 dBV maximum at mic gain position
+10 dBV maximum at 0 dB gain position
