Shure MX150B/C-TQG Subminiature Lavalier Condenser Microphone Cardioid

Product Overview

The Shure MX150B is a professional subminiature electret condenser lavalier microphone from the Microflex series, designed for low-profile installed audio applications requiring discreet placement and reliable speech capture. CommShield technology provides superior RF immunity from cellular devices and digital wireless transmitters, making the MX150B well-suited for conference rooms, lecture halls, and houses of worship where dense RF environments are common. Available with a TQG connector (for direct use with Shure 4-pin TA4F wireless bodypack transmitters) or with an XLR version including the in-line RK100PK preamplifier for wired applications. Each unit ships with a multi-position tie clip, snap-fit foam windscreen, and equalization cap.

Product Description

The MX150B's subminiature form factor and Kevlar-reinforced soft-flex cable allow for discreet placement across television broadcast, corporate AV teleconferencing, A/V integration, and sound reinforcement applications. The Kevlar-reinforced cable reduces handling noise while maintaining flexibility for repeated daily use in installed or rental AV environments. The multi-position tie clip integrates cable management for minimized handling noise and flexible mounting configurations on clothing, lecterns, or stage elements. CommShield technology is a meaningful spec for commercial AV deployments: in environments with smartphones and dense digital wireless infrastructure, RF immunity directly affects audio quality and integrator reliability. The TQG version connects directly to any Shure TA4F bodypack transmitter; the XLR version includes an in-line preamplifier for wired mixer inputs and phantom-powered connections.

Key Features

• CommShield RF Immunity Technology — Specifically designed to resist interference from cellular devices and digital bodypack wireless transmitters, maintaining clean audio in RF-dense conference rooms, worship spaces, and corporate AV environments.
• Omnidirectional Polar Pattern — 360° pickup maintains consistent audio level as the talent's position and orientation shifts relative to the capsule, reducing gain-riding demands in live mixing and conferencing workflows.
• Subminiature Low-Visibility Design — Ultra-compact form factor for discreet placement in broadcast, corporate communications, and installed sound applications where microphone visibility must be minimized.
• TQG and XLR Connector Options — TQG version connects directly to Shure 4-pin TA4F wireless bodypack transmitters; XLR version ships with the RK100PK in-line preamplifier for phantom-powered wired connections to mixing consoles and AV processors.
• Equalization Caps Included — Interchangeable equalization caps allow high-frequency response shaping for different speech and performance applications without requiring external EQ processing.
• Kevlar-Reinforced Soft-Flex Cable — Mechanically durable cable construction designed to reduce handling noise and withstand repeated daily use in professional installed and rental AV environments.
• Multi-Position Tie Clip — Flexible cable management and mounting system for reduced cable handling noise and versatile placement options on clothing, lecterns, or presentation surfaces.
• 143 dB Maximum SPL (TQG, Omnidirectional) — Generous headroom for close-placement vocal capture without distortion, accommodating both speech and high-level performance sources.
