Shure QLXD2/B87A Digital Handheld Wireless Microphone Transmitter

The Shure QLXD2/B87A=-H50 is a digital handheld wireless microphone transmitter that delivers clear vocal reproduction and dependable wireless performance for demanding live and installed sound applications.

Its Beta 87A supercardioid condenser capsule offers a frequency response tailored for voice, while the tight pickup pattern helps keep background noise and feedback under control. Singers appreciate the smooth high-end detail that lets vocals cut through a mix, and presenters gain extra intelligibility in rooms where echoes are common.

The transmitter operates in the UHF range from 534 to 598 MHz and provides 2560 selectable frequencies, making it easier to find a clean channel at festivals, conference centers, and other locations with crowded airwaves. A transmission range of up to 330 feet allows performers, worship leaders, and speakers to move freely without signal dropouts.

Two standard AA batteries power the unit for as much as nine hours. For longer events, the optional Shure SB900A lithium ion rechargeable battery extends operation beyond ten hours and enables real-time monitoring of remaining charge.

AES 256-bit encryption keeps corporate meetings and worship services secure from unauthorized listening. Adjustable input sensitivity, frequency lockout, and power lockout give engineers precise control, while one-touch infrared syncing pairs the transmitter with compatible QLX-D receivers in seconds.

The housing, made from durable aluminum, withstands the rigors of touring and daily use. Because the system balances professional sound quality with quick setup, it suits rental houses, churches, theaters, and event production crews that need reliable wireless speech and vocal reproduction every time.
