Shure 522 Dual Impedance Desktop Base Station Dynamic Microphone for Public Address and Paging Applications
The Shure Model 522 is a dynamic base station microphone designed especially for indoor communication systems such as 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. The 522 is suitable for high noise environments.
Press-to-Talk Switch is lockable, for microphone and an external relay or control circuit. Microphone circuit normally shorted in both high and low impedance. Use the switch located under the microphone base, near the cable entry, to select high (HI) or low (LO) impedance. Use the low-impedance position for long cable lengths under conditions of severe hum disturbance. Use Shure Model A95 Series Line Matching Transformers when using a low-impedance microphone line with a high-impedance amplifier input.
