522
Voice Communication Microphone

General 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 of­

fice machines. It also can reduce feedback in public address paging applications.

Features

Dual impedance (19 to 300 ohms or High)

Impedance change switch for convenient change-over

Finger-tip control bar (locking or non-locking action) to actuate microphone circuit and an external relay or control circuit

Long-life swtich to satisfy rigorous requirements of communications and paging systems

Sturdy, high impact ARMO-DUR , base and microphone case

Adjustable microphone height

Dependable under most operating conditions

Press-To-Talk Switch Operation

Press and hold the bar switch to talk. To lock the switch, press and pull it forward. To unlock the switch, move the bar back and 

release.
