Shure 522 Dynamic


The Model 522 is a dynamic base station microphone designed especially for radio communications, paging, and dispatching systems. Its cardioid (unidirectional) pickup pattern suppresses unwanted background noise - the type of noise generated by other dispatchers working nearby, by ventilating equipment, or by office machines in the same area. It also eliminates or reduces feedback in public address paging applications.Features * Dual impedance (19 to 300 ohms or High)

    Most users do not need a license to operate a wireless microphone system. Nevertheless, operating a 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
