Shure QLXD2/B87C Handheld Transmitter with Beta87C Microphone

Product Overview

The Shure QLXD2/B87C is a QLD-D digital wireless handheld transmitter fitted with the Beta 87C supercardioid condenser capsule, designed for wireless vocal applications in presentation spaces, houses of worship, music venues, and commercial AV installations. Delivering transparent 24-bit digital audio over a 100-meter operating range, the QLXD2 pairs with any QLXD4 series receiver for a complete digital wireless microphone system. Its all-metal construction and interchangeable capsule design make it a practical choice for integrators and AV system designers specifying wireless mic systems for permanent or touring deployments.

Product Description

The QLXD2 transmitter body accepts the Beta 87C capsule via Shure's RPW capsule system, allowing straightforward capsule swaps to match application requirements without replacing the transmitter. The Beta 87C's supercardioid polar pattern provides off-axis rejection suited to gain-before-feedback sensitive environments including podiums, stages, and lecterns. One-touch IR sync with a paired QLXD4 receiver streamlines system deployment and frequency coordination. An optional SB900C rechargeable lithium-ion battery provides up to 10 hours of continuous use with runtime reported in hours and minutes. For an SM58-capsule variant, see the Shure QLXD2/SM58 Handheld Transmitter.

Frequently Asked Questions

Which receiver is required to complete a system with the QLXD2/B87C?
The QLXD2/B87C requires a Shure QLXD4 single-channel or QLXD4Q quad-channel digital wireless receiver in the same frequency band. Frequency bands must match for proper system operation.

Can the capsule on the QLXD2/B87C be changed?
Yes. The QLXD2 transmitter body uses Shure's RPW interchangeable capsule system. Replacement capsules including the SM58 (RPW112), Beta 87A (RPW120), KSM9 (RPW184), and others can be swapped in without replacing the transmitter body.

What is the difference between the Beta 87C and Beta 87A capsule?
Both are high-output condenser capsules. The Beta 87C features a supercardioid polar pattern optimized for stage vocal use with enhanced gain-before-feedback. Consult Shure's capsule comparison documentation to determine which suits your specific application.

Is the QLXD2/B87C suitable for permanent AV installation?
Yes. The QLD-D digital system's efficient RF usage, IR sync setup, and durable all-metal transmitter body make it well-suited for fixed-installation commercial AV environments including corporate presentation rooms, government spaces, and houses of worship.
