Shure UL4 UniPlex – Cardioid Subminiature Lavalier Microphone (Black, LEMO)

Product Overview

The Shure UL4 UniPlex is a MEMS-capsule cardioid subminiature lavalier microphone engineered for speech clarity in broadcast, corporate AV, conference, and presentation environments. Its cardioid polar pattern provides directional pickup that reduces room noise, off-axis speaker bleed, and ventilation noise compared to omnidirectional lavaliers — a meaningful advantage in acoustically live commercial meeting spaces, auditoriums, and broadcast studios. The 3-pin LEMO connector on this variant is compatible with Shure wireless bodypack transmitters that accept the LEMO termination, including select models in the ULXD and SLXD series. With a 40 Hz–20 kHz frequency response and a 130 dB maximum SPL rating, the UL4 handles the full range of speech and vocal applications without distortion or frequency-response compromises.

Product Description

The UL4 UniPlex is built around a MEMS microphone capsule, a solid-state transducer technology that provides consistent sensitivity across temperature and humidity variations — an advantage in commercial AV installations where environmental conditions vary. The 5 mm capsule size is discrete enough for most presenter placement scenarios while maintaining the sensitivity and dynamic range required for professional broadcast and commercial AV audio chains. The 1.6 mm Shure Plex cable incorporates a dual-redundant ground designed for extended flex life, an important specification for high-use environments where cables are repeatedly coiled, uncoiled, and repositioned. The superhydrophobic coating on both the capsule and cable resists perspiration and humidity. The black finish and matte cable suit darker clothing and skin tones. The accessories-included (-A) variant provides mounting hardware and windscreens for diverse placement configurations across government, educational, and corporate AV deployments.

Key Features

• MEMS Cardioid Capsule — Solid-state MEMS transducer technology provides consistent performance across temperature and humidity variations in commercial AV environments.
• Directional Cardioid Pickup — Reduces off-axis room noise, HVAC, and ambient bleed compared to omnidirectional designs, improving intelligibility in reflective commercial spaces.
• Full-Range Frequency Response (40 Hz–20 kHz) — Captures natural voice reproduction without low-frequency rolloffs common in smaller lavalier microphone designs.
• Low Self-Noise (32 dB SPL-A) — Suitable for close-miked speech and quiet presenter applications in conference rooms, government chambers, and broadcast studios.
• High Maximum SPL (130 dB) — Handles elevated vocal levels without distortion in high-SPL presentation environments.
• 3-Pin LEMO Connector — Compatible with Shure wireless bodypack transmitters accepting LEMO termination, integrating directly into existing Shure wireless infrastructure.
• 1.6 mm Shure Plex Cable with Dual-Redundant Ground — Extended flex life cable construction suited to frequent use in corporate and broadcast lavalier workflows.
• Superhydrophobic Coating — Capsule and cable resist perspiration and environmental moisture for reliable performance during extended on-talent use.

Frequently Asked Questions

Which Shure wireless systems use the 3-pin LEMO connector?

The 3-pin LEMO connector is used on select Shure bodypack transmitters, including specific models in the ULXD and SLXD series configured for LEMO termination. Verify your bodypack model's connector type in the Shure documentation before ordering.

Why choose a cardioid lavalier over an omnidirectional model for speech applications?

Cardioid lavaliers attenuate sound arriving off-axis, reducing pickup of room acoustics, HVAC noise, and monitor bleed in commercial AV spaces. This can improve intelligibility and reduce post-processing requirements, particularly in reverberant rooms or multi-speaker environments. Omnidirectional lavaliers generally provide more forgiving placement and lower sensitivity to handling noise when the talent moves.

Is the UL4 compatible with the Shure Axient Digital system?

Compatibility depends on the specific Axient Digital bodypack transmitter model and its connector configuration. Consult the Shure compatibility documentation or contact Creation Networks to confirm that the 3-pin LEMO variant is compatible with your specific Axient Digital bodypack before purchase.

What does the -A suffix indicate?

The -A suffix denotes the accessories-included package, which ships with mounting hardware, clothing clips, and windscreens to support a range of placement scenarios without requiring separate accessory orders.
