Note: This system does NOT include a bodypack transmitter. However, because Shure uses universal packaging for this and other wireless systems, the packaging may have an empty spot where a bodypack would fit. This space is intentionally empty.

Working Range: 91 m (300 ft) Line of Sight (Note: Actual range depends on RF signal absorption, reflection and interference)
Audio Frequency Response: 50 to 15,000 Hz (Dependent on microphone type)
Total Harmonic Distortion: Ref. +/-33 kHz deviation with 1 kHz tone, 0.5%, typical
Dynamic Range: 100 dB, A-weighted, typical
Operating Temperature: -18*C (0*F) to 57*C (135*F) (Note: Battery characteristics may limit this range)

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.

RF Sensitivity: -105 dBm for 12 dB SINAD, typical
Image Rejection: >50 dB, typical

Consumer Alert

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC's wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones

NOTE: None of the wireless systems we carry are capable of violating the FCC guidelines stated above. We are presenting this information as a matter of legally required disclosure.
