The Shure SLXD14/DL4B is a complete digital wireless system configured with a rugged, omnidirectional lavalier microphone featuring Shure's proprietary DuraPlex element. This system pairs the reliable SLXD1 bodypack transmitter with the DL4B lavalier capsule, which is built for high-impact performances and demanding environments. The DL4B utilizes the dynamic DuraPlex transducer, which is engineered to be exceptionally resistant to damage from moisture, wind, and physical shock. Its omnidirectional polar pattern captures sound naturally from all directions, providing a consistent, open tone that is less susceptible to plosives and tonal changes caused by head movement, making it ideal for active presenters, fitness instructors, and theatrical performers.

The system operates on the UHF band with 24-bit digital transmission, delivering clear, interference-free audio with a wide dynamic range. The SLXD1 transmitter is compact and durable, with a metal casing and a locking connector for the lavalier cable. It is powered by two AA batteries for extended use. The included SLXD4 dual-channel receiver provides true diversity reception and a backlit display for monitoring system status. The combination of the robust DL4B microphone and the reliable SLXD digital wireless creates a system that can withstand the rigors of sweat, movement, and challenging conditions while delivering consistent, intelligible audio.

This system is specifically designed for applications where durability is as important as sound quality. It is a premier choice for live events, broadcast sports, outdoor productions, and any scenario where a lavalier microphone is subjected to physical stress or environmental challenges. The SLXD14/DL4B ensures that performers have the freedom to move and express themselves fully without worrying about microphone failure.
