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.

Impedance Selection
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.
Logic Connections
The RED and BLACK leads may be used to control an external relay or switching circuit.
Audio Connections
Unbalanced high-impedance operation:
Set the impedance switch to the HI position (as shipped). Connect the GREEN cable lead and the shield to the amplifier chas
sis ground. The WHITE cable lead is the "hot" conductor.
Balanced-line low-impedance operation:
Set the impedance switch to the LO position. Connect the shield to the amplifier chassis ground. The WHITE and GREEN ca
ble leads are the "hot" conductors.
