Shure QLXD2/B87A Handheld Transmitter with Beta87A Microphone

Product Overview

The Shure QLXD2/B87A is a professional QLX-D digital wireless handheld transmitter fitted with the Beta 87A supercardioid condenser capsule, targeting commercial AV deployments where vocal intelligibility and studio-level audio quality are priorities. The condenser element delivers extended high-frequency response and low self-noise — characteristics that suit controlled acoustic environments including executive boardrooms, broadcast studios, training rooms, and all-hands rooms. Operating on Shure's 24-bit digital wireless platform with a 100 m (328 ft) range and AES-256 encryption, the QLXD2/B87A integrates into managed AV infrastructure via the QLXD4 receiver's Ethernet control interface.

Product Description

The Beta 87A condenser capsule distinguishes the QLXD2/B87A from dynamic-capsule alternatives in the QLX-D line: the condenser element captures the full frequency range with greater detail and sensitivity, making it the preferred choice for presenters, vocalists, and corporate communications in acoustically treated spaces. The transmitter body is machined aluminum, operates at 1 mW or 10 mW RF output, and syncs with the QLXD4 receiver via IR in seconds — reducing commissioning time for multi-channel wireless installations. Five frequency bands (G50, H50, J50A, V50, X52) and support for over 60 compatible channels per band give AV integrators the flexibility to deploy multiple wireless systems in RF-dense facilities. AES-256 encryption is available for installations in government or executive environments with confidentiality requirements.

For a complete QLX-D system, pair with the Shure QLXD4 single-channel digital wireless receiver at Creation Networks. Integrators requiring a premium KSM9 capsule for demanding vocal applications may also consider the Shure QLXD2/KSM9.

Key Features

• Beta 87A Supercardioid Condenser Capsule — The condenser element delivers extended frequency response and low self-noise, capturing vocal detail with accuracy suited to broadcast, corporate communications, and acoustically treated conference environments.
• 24-Bit Digital Audio — Shure QLX-D's proprietary digital transmission achieves an audio dynamic range exceeding 120 dB (A-weighted, typical) with less than 2.9 ms system latency.
• 100 m (328 ft) Operating Range — Line-of-sight RF coverage for large conference rooms, auditoriums, and multi-purpose rooms without requiring antenna distribution in standard deployments.
• AES-256 Encryption — End-to-end audio encryption for government spaces, executive boardrooms, and any facility with audio confidentiality requirements.
• IR Sync for Fast Setup — One-button synchronization with the QLXD4 receiver transfers frequency and group settings in seconds, accelerating installation and event changeover workflows.
• Selectable RF Power (1 mW / 10 mW) — Two transmit power settings allow integrators to manage RF coexistence in dense wireless environments while maintaining adequate operating range.
• 60+ Compatible Channels per Band — High-density RF spectrum usage supports large multi-channel deployments within a single frequency band, reducing coordination complexity.
• Dual Power Options — Two AA alkaline batteries (~8 hours) or Shure SB900C rechargeable Li-Ion battery (>11 hours on standard UHF bands) support both disposable and managed battery workflows.
• Interchangeable RPW-Series Capsules — The QLXD2 transmitter body accepts Shure wireless RPW-series capsules (SM58, Beta 58A, KSM9, and others) for capsule changes without replacing the transmitter.
• Network Integration via QLXD4 Receiver — Ethernet control supports Wireless Workbench 6, ShurePlus Channels app, and AMX/Crestron integration for unified room control workflows.

Typical Applications

• Executive boardroom and corporate conference room wireless vocal systems
• All-hands room and town hall presentation environments
• Broadcast studio and corporate video production vocal capture
• House of worship vocal reinforcement in acoustically treated sanctuaries
• Training room and government space wireless AV installations
• Multi-purpose room systems requiring high-clarity condenser wireless

Technical Specifications

Frequently Asked Questions

How does the Beta 87A capsule differ from the Beta 58A on the QLXD2/B58?
The Beta 87A is a condenser capsule offering extended high-frequency response and lower self-noise compared to the Beta 58A dynamic capsule. The Beta 87A is the preferred choice for controlled acoustic environments such as conference rooms and broadcast studios; the Beta 58A is better suited for high-SPL live performance environments with monitor proximity.

What receiver does the QLXD2/B87A require?
The QLXD2/B87A operates with the Shure QLXD4 single-channel digital wireless receiver. Transmitter and receiver must be in the same frequency band. Cross-system use with ULX-D receivers is also supported with encryption set to Off.

What frequency band should I specify at time of purchase?
Frequency band availability is governed by local RF licensing. Use Shure's Frequency Finder at shure.com or contact Creation Networks to confirm which band is authorized in your region before ordering.

Is AES-256 encryption available on this transmitter?
Yes. AES-256 encryption is enabled via the QLXD4 receiver menu. It applies to QLX-D component pairings only; cross-system use with ULX-D requires disabling encryption on both units.

Can the Beta 87A capsule be swapped for another capsule?
Yes. The QLXD2 transmitter body accepts Shure wireless RPW-series capsules, including the SM58, Beta 58A, Beta 87C, KSM9, and others, without replacing the transmitter body.

Does the QLXD4 receiver support Crestron or AMX control?
Yes. The QLXD4 connects via Ethernet (TCP/IP, port 2202) for AMX and Crestron integration, supporting unified room control and remote monitoring in commercial AV installations.
