System Technical Specifications
Buy with Confidence
75m (250 ft.) Note: actual range depends on RF signal absorption, reflection, and interference.
Audio Channel Response
Minimum: 45 Hz. Maximum: 15 kHz (overall system channel depends on microphone element).
Total Harmonic Distortion
0.5%, typical Ref. +/– 33 kHz deviation, 1 kHz tone
>100 dB A-weighted, typical
Operating Temperature Range
–18°C (0°F) to +57°C (+135°F) Note: battery characteristics may limit this range
Transmitter Audio Polarity
Positive pressure on microphone diaphragm (or positive voltage 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.
All wireless microphone systems available through AMS are compliant with current FCC rules for safe operation without a license when they leave our warehouse. If you choose to modify a system after purchase, it may no longer be in compliance and may therefore require a license to operate. To learn more about the FCC’s rules regarding wireless microphones (which are subject to change), please call the FCC at 888-CALL-FCC (TTY: 888-TELL-FCC) or visit http://www.fcc.gov/encyclopedia/wireless-microphones.
