Product Description

The Model 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.

Features

  • Frequency response tailored for voice communications
  • Directional microphone element
  • Switch-selected dual impedance output
  • Finger-tip control bar (locking or non-locking action) to actuate microphone circuit and an external relay or control circuit
  • Long-life switch to satisfy rigorous requirements of communications and paging systems
  • PTT switch that can be locked “On” for hands-free operation
  • Four conductor, shielded, bare-ended (no connector), straight cable
  • Adjustable height
  • Does not require DC power for operation
