Shure ADX2FDTA/B87A=-G57 Digital Handheld Wireless Microphone Transmitter with Beta 87A Capsule (G57: 470 to 616 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2FD/B87A is a TAA-compliant Axient Digital handheld wireless microphone transmitter featuring Frequency Diversity technology and the Beta 87A condenser supercardioid capsule. Operating in the G57 frequency band (470–616 MHz) with up to 184 MHz of tuning range, the ADX2FDTA/B87A=-G57 is engineered for high-reliability commercial AV applications requiring the sensitivity and detail of a condenser capsule—including broadcast, theater, government press events, and professional AV productions. ShowLink remote control enables real-time parameter adjustments via Wireless Workbench 6 without interrupting active audio.

Product Description

The Frequency Diversity architecture of the ADX2FD transmits the RF signal simultaneously on two discrete carriers within the same frequency band. If one carrier encounters interference, the receiving system automatically favors the stronger signal, providing RF redundancy not available on standard single-carrier wireless systems. The Beta 87A condenser supercardioid capsule delivers exceptional audio quality with high sensitivity and detail, making this transmitter well suited for vocal applications in broadcast, theater, and professional AV environments where audio fidelity is critical. The metal chassis construction provides durability for live productions, and the transmitter is compatible with all Axient Digital receivers when matched to the G57 band. Two SB920A lithium-ion rechargeable batteries are included. For a complementary Axient Digital bodypack transmitter, see the Shure ADX1M Micro Bodypack Wireless Transmitter. For a Frequency Diversity handheld with a dynamic capsule, see the Shure ADX2FD/K8N with KSM8 Capsule.

Key Features

• Frequency Diversity (Dual Carrier) — Transmits the RF signal on two discrete carriers simultaneously, providing automatic redundancy against interference on either carrier and improving signal reliability in RF-congested commercial AV environments.
• Beta 87A Condenser Supercardioid Capsule — The Beta 87A delivers high sensitivity, extended frequency response, and detailed audio reproduction for broadcast, theater, and professional AV productions requiring condenser-grade fidelity from a wireless handheld transmitter.
• Wide Tuning Range (Up to 184 MHz) — Tunes across up to 184 MHz within the G57 band (470–616 MHz), giving RF coordinators flexibility to deploy large channel counts and avoid local interference.
• Diversity ShowLink Remote Control — Real-time adjustment of gain, mute, RF power, and other parameters via Wireless Workbench 6 without interrupting active audio.
• Encryption-Enabled Secure Transmission — On-board encryption supports secure audio transmission for government facilities, defense installations, and corporate environments with strict AV security requirements.
• Metal Construction — The metal chassis provides durability for live productions and commercial deployments with a professional appearance suited to broadcast and government AV environments.
• Includes Two SB920A Rechargeable Batteries — Two SB920A lithium-ion rechargeable batteries are included, supporting extended-runtime productions and multi-session events.
• Interchangeable Capsule System — RPW-series wireless capsules are compatible with the ADX2FD, allowing the capsule to be swapped to suit different acoustic requirements across applications.
• TAA Compliant — Meets Trade Agreements Act requirements for U.S. federal procurement on GSA Schedule contracts and other government contracting vehicles.

Frequently Asked Questions

Which Axient Digital receivers are compatible with the ADX2FDTA/B87A=-G57?
The ADX2FD is compatible with all Axient Digital receivers, including the ADX4D dual-channel and ADX4 quad-channel rack-mount units, when matched to the G57 frequency band (470–616 MHz).

What is the difference between the Beta 87A and Beta 58A capsule variants of the ADX2FD?
The Beta 87A is a condenser supercardioid capsule that provides higher sensitivity, extended frequency response, and more detailed audio reproduction, making it well suited for broadcast, theater, and applications requiring condenser-grade fidelity. The Beta 58A is a dynamic supercardioid capsule that is more tolerant of high sound pressure levels, making it a practical choice for general live vocal and spoken word applications.

What does Frequency Diversity add in a commercial AV environment?
Frequency Diversity transmits the audio signal on two discrete RF carriers simultaneously. If one carrier encounters interference, the receiver automatically favors the stronger signal, reducing dropout risk in RF-congested environments such as large government facilities, broadcast studios, and enterprise event spaces.

Is the ADX2FDTA/B87A=-G57 eligible for U.S. federal government procurement?
Yes. The TA= suffix confirms Trade Agreements Act (TAA) compliance, qualifying this transmitter for GSA Schedule contracts, federal agency purchases, and other government procurement vehicles.

Can the Beta 87A capsule be replaced with a different capsule?
Yes. The ADX2FD is compatible with RPW-series interchangeable wireless capsules, including the RPW120 (wireless Beta 87A), allowing capsule swaps to suit specific acoustic requirements.

What warranty applies to the ADX2FD?
Shure provides a two-year limited warranty on the ADX2FD transmitter. Creation Networks supports warranty claims and provides authorized service for commercial AV customers.
