Shure SLXD14/DL4B Digital Wireless DuraPlex Omni Lavalier Microphone System

The Shure SLXD14/DL4B-H55 is a digital wireless lavalier system created for professionals who cannot risk dropouts or muddy audio. It pairs the SLXD1 bodypack transmitter with the DL4 DuraPlex omnidirectional microphone, delivering 24-bit digital sound that stays clean and consistent from the quietest whisper to a 120 dB peak. Videographers, event hosts, educators, and houses of worship can trust it to capture speech or performance with clarity that holds up in post-production and live reinforcement alike.

Setup moves quickly. Power up, let the receiver scan for an open frequency, and complete the IR sync; in seconds the system locks to a stable RF channel with a line-of-sight range that reaches roughly 328 feet. Up to 32 compatible systems can operate in a single frequency band, which makes it a practical choice for multi-mic productions or busy AV installations.

The DL4 lavalier stands up to demanding locations. Its IP57 rating keeps dust and water at bay, so it thrives on outdoor shoots, fitness classes, and long conference days. The omnidirectional capsule picks up speech evenly, giving presenters freedom to move without worrying about mic position.

On the transmitter, an OLED screen shows frequency, battery status, and gain at a glance. A pair of AA batteries powers the pack for as long as eight hours, allowing an entire workday or performance schedule before a change is needed. For fixed installations or extended shoots, optional Shure rechargeable packs offer even more convenience.

Whether you are filming an interview across a busy expo floor, leading a corporate seminar, or engineering a church service with multiple speakers, the SLXD14/DL4B-H55 provides the reliable wireless link and natural sound quality that keep audiences focused on the message, not the technology.
