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