Shure DL4 DuraPlex Series Lavalier Microphone (Black)

Product Overview

The Shure DL4 DuraPlex is a professional MEMS condenser lavalier microphone rated IP57 for dust resistance and waterproof operation, designed for commercial AV, broadcast, theater, and performance applications where environmental durability is a hard requirement. The omnidirectional subminiature capsule measures just 5.2 mm in diameter, providing discreet placement options across a wide range of talent mounting configurations. With a frequency response of 20 Hz to 20 kHz and a maximum SPL handling of 132 dB, the DL4 delivers professional audio quality in both controlled and demanding field environments. The Black (DL4B) variant is available with MTQG or LM3 connector options for compatibility with Shure TA4F-based wireless bodypack transmitters.

Product Description

Built on Shure's Plex cable platform, the DL4 features a 1.6 mm cable with dual redundant ground construction that resists kinking, accepts paint for concealment, and exhibits no memory effect — practical advantages for professional installations where cable management and repeated use matter. The IP57 certification means the DL4 can be submerged in water up to 1 m for 30 minutes and withstands dust ingress without compromising audio performance, making it suitable for outdoor events, broadcast sports audio, and high-activity theatrical productions. A presence cap is included for optional 3–4 dB vocal presence boost near 10 kHz, allowing the integrator or sound designer to tailor frequency response to speech applications without EQ processing at the console. Each unit ships with a carrying case, single tie clip, sticky mount, snap-fit windscreen, and foam windscreen.

Key Features

• IP57 Waterproof and Dust-Resistant Rating — Certified submersible to 1 m for 30 minutes and dust-protected per IEC IP57, enabling use in outdoor, broadcast, sports audio, and high-sweat performance environments where standard lavaliers would fail.
• MEMS Condenser Capsule — Micro-electromechanical system (MEMS) transducer technology provides consistent, high-reliability audio capture with minimal variation unit-to-unit, important for professional broadcast and live production workflows.
• Omnidirectional Polar Pattern — 360° pickup delivers consistent level as the talent moves and the microphone orientation changes, reducing the gain-riding demands on the mixing operator in live and broadcast environments.
• 5.2 mm Subminiature Design — Ultra-compact capsule dimensions allow placement options under clothing, behind a tie, or on a headset bridge with minimal visual impact for camera and audience-facing productions.
• 1.6 mm Shure Plex Cable — Paintable, kink-resistant cable with dual redundant ground construction for improved mechanical and electrical durability over standard lavalier cables in high-use professional environments.
• Presence Cap Included — Optional 3–4 dB boost near 10 kHz enhances vocal clarity and presence in speech reinforcement applications without requiring external EQ.
• High RF Immunity — Compatible with digital wireless systems without RF interference, validated for use in wireless environments with dense RF infrastructure.
• 132 dB Maximum SPL Handling — Generous headroom accommodates high-level sources close to the capsule without distortion at 1 kHz and 1% THD.
• Comprehensive Accessory Kit — Ships with carrying case, single tie clip, sticky mount, snap-fit windscreen, foam windscreen, and threaded TA4F adapter for flexible deployment from day one.

Typical Applications

• Broadcast studio and field production audio capture
• Theatrical production and performance vocal reinforcement
• Corporate events and training room wireless AV systems
• Outdoor events and sports broadcast in adverse weather
• House of worship and auditorium lavalier deployment

Technical Specifications

Frequently Asked Questions

What wireless transmitters is the DL4 compatible with?
The DL4 with MTQG connector is compatible with all Shure TA4F bodypack transmitters, including the ULXD1, QLXD1, SLXD1, and AD1 series. LEMO-terminated variants are also available for Shure LEMO-based bodypacks (AD1/ADX1-Lemo, UR1M-Lemo, ULXD1-Lemo). Third-party compatibility with Lectrosonics and Q5X systems requires specific wiring configurations — consult the DL4 user guide for wiring diagrams.

What does the IP57 rating mean for real-world use?
IP57 means the DL4 is protected against dust ingress sufficient to maintain normal operation (IP5) and can be submerged in up to 1 m of water for 30 minutes (IP7). In practice, this covers heavy rain, sweat from talent, incidental splashing, and outdoor field production conditions that would damage a non-rated lavalier.

What is the presence cap used for?
The included presence cap clips onto the microphone capsule and adds a 3–4 dB boost in the presence frequency range near 10 kHz. This tailors the frequency response for speech intelligibility and vocal clarity in conference room, broadcast interview, and presentation applications without requiring additional EQ at the mixing console or processor.

Can the DL4 cable be painted for concealment under clothing?
Yes. The Shure Plex 1.6 mm cable is paintable, allowing the cable to be color-matched to skin tone or wardrobe for theater and broadcast applications where cable visibility is a production concern.

Is the DL4 available in other colors?
Yes. The DL4 DuraPlex series is available in Black, Cocoa, Tan, and White to match a range of skin tones and wardrobe applications. All colors share the same audio specifications and accessories.
