Shure QLXD2/SM87 — Handheld Wireless Transmitter with SM87 Capsule (H50)
QLXD2/SM87 Overview
The Shure QLXD2/SM87 is a professional handheld wireless transmitter combining the QLXD2 body with the SM87 condenser capsule, designed for demanding vocal applications in music venues, houses of worship, and presentation environments. It delivers 24-bit digital audio quality with efficient RF spectrum usage across the H50 band (534-598 MHz), providing reliable, transparent wireless performance. IR sync with a compatible QLXD receiver streamlines setup, and the system maintains a clear, uninterrupted signal over its full 100 m (330 ft.) operating range. This transmitter is well suited for audio engineers, system integrators, and technical directors who require consistent wireless vocal performance in fixed-installation and live-sound environments.
All-metal construction provides the durability required for regular use in touring and installed applications, and compatibility with a wide selection of Shure capsules allows operators to tailor the system to specific vocal or speech reinforcement needs.
