522 - Overview

The Shure 522 is a dynamic base-station microphone for radio communications, paging, and dispatching systems. Its cardioid (unidirectional) pickup pattern suppresses unwanted background noise from nearby dispatchers, ventilating equipment, or office machines. It also can reduce feedback in public address paging applications. This dual impedance desktop mic can also suppress unwanted background noise in public address/paging applications. Designed for indoor communication systems - fixed station - including police, fire, transportation, restaurant, and industrial applications. Suitable for high noise environments.
