Shure ADX2/B87A Digital Handheld Wireless Microphone Transmitter with Beta 87A Capsule

Product Overview

The Shure ADX2/B87A is a premium Axient Digital handheld wireless transmitter fitted with the Beta 87A supercardioid condenser capsule, optimized for vocal applications in broadcast studios, corporate all-hands rooms, houses of worship, and auditorium installations. ShowLink remote control allows real-time frequency changes and muting from Wireless Workbench, while AES 256-bit encryption ensures secure audio transmission in sensitive environments. With a 184 MHz tuning range and High Density mode support, the ADX2/B87A is a professional Axient Digital wireless solution for commercial AV integrators managing complex multi-channel systems.

Product Description

The ADX2/B87A pairs the ADX2 transmitter body—the premium tier of the Axient Digital handheld line—with the Beta 87A condenser capsule, which delivers extended frequency response and a tighter supercardioid pickup pattern compared to dynamic capsules. This makes it well-suited to controlled acoustic environments like broadcast studios, conference rooms, and performing arts centers where ambient rejection and vocal clarity are priorities. The transmitter features selectable RF output (2/10/40 mW), allowing integrators to configure for close-range high-density deployments or extended line-of-sight range up to 100 meters. ShowLink diversity control links to the Wireless Workbench network for centralized management of transmitter parameters across large wireless deployments. The SB920A rechargeable lithium-ion battery provides up to 9 hours of runtime at 10 mW, with precision hours-and-minutes metering on the receiver display.

Integrators building out complete Axient Digital systems can pair this transmitter with the Shure ADX1 Axient Digital Bodypack Transmitter for a unified ShowLink-managed wireless platform.

Key Features

• ShowLink Remote Control — IEEE 802.15.4 diversity link enables real-time remote management of frequency, power, mute, and channel naming from Wireless Workbench without interrupting audio.
• Beta 87A Supercardioid Condenser Capsule — Extended frequency response with tight polar pattern delivers natural vocal reproduction with strong off-axis rejection, suited for studio and controlled-room environments.
• 184 MHz Tuning Range — Wide spectrum agility supports precise frequency coordination in RF-dense commercial deployments.
• AES 256-Bit Encryption — Secure audio transmission for government spaces, executive conference rooms, and broadcast facilities.
• High Density Mode — Reduces channel-to-channel spacing to 125 kHz, enabling higher simultaneous channel counts in limited spectrum.
• Selectable RF Output: 2/10/40 mW — Adjustable power accommodates high-density system design or extended-range deployment scenarios.
• SB920A Rechargeable Battery — Lithium-ion power with dockable charging contacts; up to 9 hours runtime at 10 mW, with precision time-remaining metering.
• Interchangeable Capsule System — Accepts all Shure RPW-series wireless capsules for field swaps without replacing the transmitter.
• Automatic Input Staging — Automatically optimizes gain setting for consistent audio levels across varying input sources.
• Cast Aluminum Housing — Commercial-grade build quality suitable for touring inventory and permanent installation.

Typical Applications

Frequently Asked Questions

What is the difference between the ADX2/B87A and the AD2/B87A?
The ADX2/B87A includes ShowLink remote control, which enables real-time parameter management from Wireless Workbench software. The AD2/B87A uses the same Beta 87A capsule and Axient Digital RF platform but does not include ShowLink. For mission-critical large-format deployments where remote control is required, the ADX2/B87A is the appropriate choice.

Is the Beta 87A capsule interchangeable?
Yes. The ADX2 body accepts all Shure RPW-series wireless capsules. You can swap to the Beta 87C (RPW122), SM58 (RPW112), KSM9 (RPW184), or other cartridges in the field without tools.

Which Axient Digital receivers are compatible?
The ADX2/B87A works with all Axient Digital receivers: AD4D (2-channel), AD4Q (4-channel), and ADX5D (2-channel ShowLink access point). Ensure the receiver frequency band matches the transmitter band ordered.

What Shure system is required for ShowLink to function?
ShowLink requires a compatible Axient Digital receiver or a dedicated ShowLink Access Point (ADSL) connected to Wireless Workbench 6 or higher. Without a ShowLink-compatible receiver or ADSL, the transmitter still operates normally — ShowLink is an optional management layer.

What is the warranty on this product?
Shure provides a 2-year limited warranty on the ADX2/B87A. Contact Creation Networks for warranty support and service coordination.
