Model 522 User Guide

MODEL 522

BASE-STATION MICROPHONE

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. The 522 can be converted to Monitor/Transmit switching with the Shure RK199S Split- Bar Conversion Kit.

Features

Dual impedance (19 to 300 ohms or High)

lmpedance 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 switch 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

Conversion kit available for Monitor/Transmit switching

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 or chassis 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 or chassis ground. The WHITE and GREEN cable leads are the “hot” conductors.

OPTIONAL CONVERSION

Use the optional monitor split-bar with receivers that have a squelch circuit. Depressing the monitor bar disables the squelch so the operator can verify there are no other transmissions below the squelch threshold before transmitting.

The Transmit/Monitor Switch Kit is Shure Model RK199S. General microphone wiring instructions are supplied with the kit, but specific transceiver wiring details must be obtained from the transceiver schematic and/or the manufacturer of the unit.

522 specifications

The Shure 522 is a dynamic microphone well-suited for a variety of vocal applications, particularly in broadcasting, public speaking, and professional recording. Shure has long been recognized for producing high-quality audio equipment, and the model 522 continues this tradition with a robust design and impressive audio performance.

One of the primary features of the Shure 522 is its dynamic microphone element, which is known for its durability and reliability in different environments. Unlike condenser microphones, dynamic microphones do not require phantom power, making them ideal for live settings where convenience and portability are prioritized. The 522 is designed to handle high sound pressure levels without distortion, allowing it to capture loud sources such as vocals or instruments with clarity.

Signal processing technology is another significant aspect of the Shure 522. It incorporates an internal shock mount system to minimize handling noise, making it suitable for handheld applications. This feature is essential for broadcast professionals who need to maintain high audio quality while maneuvering the microphone. Additionally, the microphone's frequency response is tailored to enhance vocal presence, ensuring that speech remains intelligible and clear even in noisy environments.

The build quality of the Shure 522 is another strong selling point. Constructed from durable materials, this microphone can withstand the rigors of regular use. Its classic design, combined with a lightweight yet sturdy frame, ensures that users can enjoy a comfortable grip while minimizing fatigue during extended periods of use. The microphone’s cardioid polar pattern contributes to noise isolation, focusing on the sound directly in front while rejecting off-axis noise. This characteristic is invaluable in crowded venues or any setting where background noise may be an issue.

Overall, the Shure 522 embodies a blend of advanced technology, practical design, and user-focused features. With its dynamic element, noise-reducing capabilities, and rugged construction, it stands as a reliable choice for anyone requiring a high-performance microphone for both studio and live applications. Whether utilized by amateur enthusiasts or seasoned professionals, the Shure 522 continues to deliver exceptional sound clarity, making it an excellent addition to any audio toolkit.
