Shure SLXD14/85M Digital Wireless Cardioid Lavalier Microphone System (H55: 514 to 558 MHz)

The Shure SLXD14/85M-H55 is a digital wireless system that pairs the trusted WL185M cardioid lavalier microphone with a robust bodypack transmitter and a half-rack receiver. It gives presenters, trainers, worship leaders, and event coordinators a simple path to clear, dropout-free speech reinforcement without the complexity that often comes with multi-channel wireless setups.

You hear every nuance thanks to 24-bit digital audio that offers 120 dB of dynamic range and only 3.2 ms of latency. Voices sound natural and stay consistent, even when the speaker turns their head, because the WL185M lavalier focuses on the voice while reducing ambient noise from surrounding instruments, HVAC systems, or audience chatter.

Day-to-day operation is straightforward. Power up the SLXD4 receiver, press a single button to scan for an open frequency in the H55 band (514 to 558 MHz), then use IR sync to send that frequency to the SLXD1 bodypack. An Ethernet port lets you network several receivers for coordinated frequency management when a production calls for multiple microphones.

Portability and endurance are built in. The lightweight bodypack runs up to eight hours on two AA batteries, or on the optional SB903 rechargeable pack, and maintains a reliable link at distances up to 330 feet line of sight. With support for as many as 32 compatible channels per 44 MHz band, the system scales smoothly from a single presenter in a conference room to a full roster of actors in a small theater.

Whether you are equipping a corporate boardroom, a classroom, or a house of worship, the SLXD14/85M-H55 delivers the audio quality and operational ease that keep attention on the message, not the gear.
