Shure 522 Desktop Microphone

OVERVIEW

Designed for the desktop environment.

The Model 522 is a dynamic base station microphone designed especially for 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. The mic also eliminates or reduces feedback in public address paging applications.

SPECIFICATIONS

 

522 Desktop Microphone

Type: Dynamic

Frequency Response: 60 to 11,000 Hz

Polar Pattern: Cardioid (unidirectional) - uniform with frequency, symmetrical about axis

Impedance: Dual. Microphone rating impedance is 150 ohms (260 ohms actual) for connection to microphone inputs rated at 19 to 300 ohms and "High" for connection to high-impedance microphone inputs. Switch is in high-impedance position as supplied.

Sensitivity (AT 1,000 HZ): Open Circuit Voltage*: Low —57.0 (1.3 mV); High —38.5 dB (12 mV) (*1 Pa=94 dB SPL)

Switch: Press-to-Talk Switch - locking or nonlocking operation to actuate microphone circuit and an external relay or control circuit. Microphone circuit normally shorted in both high and low impedance; impedance Selection Switch: Double-pole double- throw slide switch in microphone base to provide either high- or low-impedance operation

Cartridge Shock Mount: Internal rubber vibration-isolator

Cable: 2.1 m (7 ft) four-conductor, two conductors shielded non-detachable

Case: Two-tone gray ARMO-DUR with dull-chrome-plated steel screen
