Technical Info
Channel Frequencies
Channel H6: 524.000 to 542.000 MHz
Channel J6: 572.250 to 589.875 MHz
Channel L5: 644.000 to 662.000 MHz
System Working Range: 100 m (300 ft.)
Note: actual range depends on RF signal absorption, reflection, and interference
Audio Frequency Response (+/- 2 dB):
Minimum: 45 Hz
Maximum: 15 kHz
(Overall system frequency depends on microphone element.)
Total Harmonic Distortion (Ref. +/- 33 kHz deviation, 1 kHz tone): 0.5 %, typical
Dynamic Range: >100 dB A-weighted
Operating Temperature Range:
18 deg. C (0 deg. F) to 50 deg. C (122 deg. 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.
