Overview

The Shure BLX14R/W85-J11 is a complete UHF wireless lavalier microphone system designed for presenters, lecturers, and performers who need hands-free audio with professional reliability. At the heart of the system is the WL185 cardioid condenser lavalier microphone, which provides focused voice pickup while minimizing ambient noise from the sides and rear. The BLX1 bodypack transmitter is compact and lightweight, running up to 14 hours on two AA batteries, and features a simple one-touch sync with the receiver for fast setup.

The BLX4R single-channel receiver is built for permanent installation, fitting into a standard 19-inch equipment rack for clean integration into conference rooms, worship spaces, and performance venues. It offers automatic frequency scanning to find clear channels and supports up to 12 compatible systems operating simultaneously in the same frequency band. With an operating range of up to 300 feet and XLR output, the BLX14R/W85 bridges the gap between entry-level wireless systems and higher-end touring rigs, providing dependable Shure quality for fixed and semi-permanent sound reinforcement applications.
