General Description

The MX150 is a professional subminiature electret condenser lavalier microphone ideal for use in speech and other applications requiring low-profile, discreet placement. Available with cardioid or omnidirectional patterns, the MX150 provides uncompromised sound quality and high reliability with minimal visibility for use in television broadcasting, corporate lectures, A/V teleconferencing, House of Worship, and sound reinforcement. CommShield^® Technology offers superior RF immunity from cellular devices and digital bodypack transmitters. Each microphone is supplied with a snap-fit foam windscreen to minimize wind noise and a multi-position tie clip with integrated cable management to minimize cable handling noise.

Model Variations

The MX150 is available in several varieties:

Ⓐ Polar Pattern

C Cardioid

O Omnidirectional

Ⓑ Connectors

TQG For Shure transmitters with 4-pin TA4F/TQG connectors

XLR Includes the RK100PK in-line preamplifier

Features

Available in cardioid or omnidirectional polar patterns and TQG (for use in Shure bodypacks) or wired XLR variations
CommShield^® Technology guards against interference from Cellular RF devices and digital bodypack transmitters
Matte black, sleek, low-profile, design for inconspicuous placement
Multi-position tie clip allows for a variety of placement options and features an integrated cable management system for convenient cable dress with minimized handling noise
Kevlar-reinforced soft-flex cable design further reduces handling noise while providing superior flexibility for routing and placement
User-changeable equalization caps for response shaping (omnidirectional only)
Snap-fit, concise windscreen provides protection from plosives and wind noise with minimal visibility
Legendary Shure quality, ruggedness, and reliability

Equalization Caps

The omnidirectional MX150B/O variations ship with two types of equalization caps for high-frequency shaping:

	Normal: Silver color screen; provides the most natural sound in most applications
	Presence Boost: Black screen; provides a smooth, high-frequency boost

The cardioid MX150B/C variations are only compatible with the gold cap shipped with the microphone. Do not use the silver and black omnidirectional screens.

Snap-fit Windscreen

Use the furnished snap-fit windscreen to provide plosive and wind protection.

Snap into the groove below the cartridge to secure to the microphone.
To remove, grab the plastic cage in the windscreen and lift over capsule.

TQG Models

Using with Other Bodypack Transmitters

When connecting the microphone to anything other than a Shure wireless bodypack, ensure the device provides a regulated +5 V DC (130 µA minimum) to the red conductor. Refer to the wiring diagram in the specifications.

XLR Models

Phantom Power

The supplied RK100PK preamplifier requires phantom power and performs best with a 48 V DC supply (IEC-61938). However, it will operate with slightly decreased headroom with supplies as low as 11 V DC.

Most modern mixers provide phantom power. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS.

RFI Filtering

This microphone features CommShield^® Technology for RF filtering. For best results in hostile RF environments, always use the RK100PK preamp furnished with the XLR versions of this microphone.

Mounting the Microphone

This microphone is furnished with a multi-position tie clip for flexible mounting options and reduced cable noise. Reference the furnished tie clip guide for placement and routing suggestions.
