Shure ADX2FD/B87A Digital Handheld Wireless Microphone Transmitter with Beta 87A Capsule

Product Overview

The Shure ADX2FD/B87A is a frequency-diverse digital handheld wireless microphone transmitter featuring the Beta 87A supercardioid condenser capsule, engineered for broadcast production, theatrical performances, and high-profile commercial AV installations where RF interference is a constant concern. As part of the Axient Digital ADX series, it transmits on two independent frequencies simultaneously, with ShowLink remote control for automatic interference avoidance during live productions. Compatible with Axient Digital AD4D and AD4Q receivers, the ADX2FD/B87A is designed for demanding live sound and broadcast environments that require maximum channel density and RF transparency.

Product Description

The ADX2FD/B87A combines the proven Shure Beta 87A studio-quality supercardioid condenser capsule with Axient Digital frequency-diverse transmission technology in a single handheld form factor. Frequency diversity means the transmitter continuously uses two separate RF transmission paths, enabling the system to maintain audio continuity even in the most congested RF environments—critical for broadcast studios, government assembly chambers, and large-venue commercial events. ShowLink technology allows engineers to adjust transmitter settings, change frequencies, and monitor RF status remotely from a Wireless Workbench 6 workstation or ShurePlus Channels app without interrupting audio. The transmitter supports Standard mode for maximum coverage and High Density (HD) mode for installations requiring a high channel count within limited spectrum. It is available in the G57 band (470–616 MHz) and integrates with the Shure AD4DNP Two-Channel Receiver or Shure AD4QUS Four-Channel Receiver for complete Axient Digital systems.

Key Features

• Frequency-Diverse Transmission — Simultaneously transmits on two independent RF frequencies, providing automatic interference avoidance and maintaining audio continuity in congested RF environments.
• Beta 87A Supercardioid Condenser Capsule — Professional studio-quality condenser capsule with tight supercardioid polar pattern for high gain-before-feedback and excellent off-axis rejection in live and broadcast settings.
• ShowLink Remote Control — Enables remote frequency changes, gain adjustments, and transmitter monitoring from Wireless Workbench 6 or ShurePlus Channels without interrupting audio.
• Standard and High Density Modes — Supports both Standard mode for optimal coverage and HD mode for maximum simultaneous channel count within limited RF bandwidth, essential for large-scale productions.
• Wide Tuning Range — Wider frequency tuning range than earlier Axient transmitters, allowing greater frequency agility and coordination flexibility across a deployment.
• Axient Digital Receiver Compatibility — Works with all Axient Digital AD4D and AD4Q receivers, fitting into existing Axient Digital wireless infrastructure.
• Transparent Digital Audio — Axient Digital’s digital audio path delivers low latency and low noise floor, maintaining vocal clarity in broadcast and live sound applications.

Frequently Asked Questions

What makes the ADX2FD different from the ADX2?
The ADX2FD adds frequency diversity: it transmits on two separate RF frequencies simultaneously. This provides automatic interference avoidance without requiring engineer intervention, making it better suited for mission-critical broadcast and live production environments.

Is the ADX2FD/B87A compatible with my existing Axient Digital receivers?
Yes. The ADX2FD/B87A is compatible with all Axient Digital AD4D and AD4Q receivers and operates in both Standard and High Density modes.

What is ShowLink and how does it help during installation and live productions?
ShowLink is Shure’s proprietary remote control technology that allows engineers to adjust transmitter frequency, gain, and other settings remotely from Wireless Workbench 6 or the ShurePlus Channels iOS app—without touching the transmitter or interrupting the audio feed. This is critical during live events where access to on-stage equipment is limited.

What warranty coverage does the ADX2FD/B87A carry?
Shure products are backed by Shure’s standard manufacturer warranty. Contact Creation Networks for commercial warranty support and service coordination options for installed AV environments.
