Shure ADX2FDTA/B58=-G57 Digital Handheld Wireless Microphone Transmitter with Beta 58A Capsule (G57: 470 to 616 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2FD/B58 is a TAA-compliant Axient Digital handheld wireless microphone transmitter featuring Frequency Diversity technology and the Beta 58A dynamic supercardioid capsule. Operating in the G57 frequency band (470–616 MHz) with up to 184 MHz of tuning range, the ADX2FDTA/B58=-G57 is engineered for high-reliability commercial AV applications where wireless signal continuity is non-negotiable—including government presentations, corporate all-hands events, and broadcast productions. ShowLink remote control enables real-time parameter adjustments from 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 a layer of RF redundancy not available on standard single-carrier wireless systems. The Beta 58A capsule is a proven dynamic supercardioid microphone element widely used in live vocal and spoken word applications across corporate AV, government, and commercial event environments. The metal chassis construction provides durability for live productions, and the transmitter is compatible with the full range of 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 condenser 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 58A Dynamic Supercardioid Capsule — The Beta 58A capsule delivers clear, articulate audio for spoken word, presentations, and live vocal applications across corporate, government, and commercial event environments.
• Wide Tuning Range (Up to 184 MHz) — Tunes across up to 184 MHz within the G57 band (470–616 MHz), giving RF coordinators the flexibility to deploy large channel counts and avoid local interference.
• Diversity ShowLink Remote Control — Operators can adjust gain, mute, RF power, and other transmitter parameters in real time 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 while maintaining a professional appearance suited to corporate 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 — The RPW-series wireless capsules are compatible with the ADX2FD, allowing the capsule to be swapped out to match the specific acoustic requirements of a given application or venue.
• 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/B58=-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 does Frequency Diversity mean for commercial AV reliability?
Frequency Diversity transmits the audio signal on two discrete RF carriers simultaneously. If one carrier encounters interference, the receiver automatically favors the stronger signal, providing a practical layer of RF redundancy that reduces dropout risk in complex commercial AV environments.

Can the Beta 58A capsule be replaced with a different capsule?
Yes. The ADX2FD is compatible with RPW-series interchangeable wireless capsules, including the RPW118 (wireless Beta 58A) and others, allowing the capsule to be swapped to suit specific acoustic requirements.

Is the ADX2FDTA/B58=-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.

What is the difference between the ADX2FD and the standard ADX2?
The ADX2FD adds Frequency Diversity technology, transmitting on two RF carriers simultaneously for improved signal reliability. The standard ADX2 transmits on a single carrier. In high-reliability commercial AV and government applications, the Frequency Diversity architecture provides meaningful protection against RF interference events.

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.
