Audio-Technica ATW-251H Wireless System, Headset

The Audio-Technica ATW-251H wireless system is designed to provide reliable performance, easy setup and clear, natural sound quality. Each Audio-Technica ATW-251H professional VHF wireless system includes a receiver and body-pack transmitter with headset on a specific crystal-controlled frequency. A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.

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.
