Shure ADX2TA/B58=-G57 Digital Handheld Wireless Microphone Transmitter with Beta 58A Capsule (G57: 470 to 616 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2TA/B58=-G57 is a professional Axient Digital handheld wireless microphone transmitter equipped with the Beta®58A supercardioid dynamic capsule, operating in the G57 frequency band (470–616 MHz). TAA-compliant for U.S. government and federally-funded education procurement, this single-carrier Axient Digital transmitter brings the proven performance of the Beta 58A to Shure’s flagship wireless platform. For commercial AV integrators and system designers who need Axient Digital’s deep management capabilities, ShowLink remote control, and TAA compliance with the Beta 58A’s high-SPL handling and tight supercardioid rejection, the ADX2TA/B58=-G57 is the specification-grade solution.

Product Description

The ADX2TA/B58=-G57 pairs the Axient Digital platform’s spectrum management and remote control capabilities with the Beta 58A supercardioid dynamic capsule. The Beta 58A delivers a tight supercardioid polar pattern with high SPL handling and neodymium magnet assembly — making it a preferred choice for high-energy live vocal performance in houses of worship, auditoriums, and commercial AV applications where feedback rejection is essential. As an ADX2 (non-FD) transmitter, this model provides up to 9 hours of battery life on the SB920A rechargeable battery. ShowLink® 2.4 GHz remote control enables real-time gain, mute, and RF parameter adjustment from front-of-house. With up to 184 MHz of G57 band tuning bandwidth, the transmitter supports complex multi-channel system coordination. For a frequency diversity version of this platform with enhanced RF protection, see the Shure ADX2FDTA/SM58=-G57.

Frequently Asked Questions

What is the difference between the ADX2TA and ADX2FDTA transmitters?
The ADX2FDTA includes Frequency Diversity (FD) — it transmits simultaneously on two independent RF carriers for enhanced interference protection. The ADX2TA is a standard single-carrier Axient Digital transmitter without frequency diversity. Both are TAA-compliant and use the same ShowLink remote control and Axient Digital receiver ecosystem. The ADX2FD is the higher-specification option for mission-critical RF environments.

What receivers are compatible with the ADX2TA/B58=-G57?
This transmitter is compatible with Axient Digital G57-band receivers, including the AD4D and AD4Q. Frequency band must match between transmitter and receiver.

Is the ADX2TA/B58=-G57 TAA-compliant?
Yes. The TA suffix confirms Trade Agreements Act compliance, qualifying this transmitter for U.S. federal, DoD, and GSA contract purchases.

What is the battery runtime for the ADX2TA?
The ADX2TA delivers up to 9 hours on the SB920A lithium-ion rechargeable battery. Compatible networked charging docks (SBC240, SBC840) allow fleet charging and battery status monitoring via Wireless Workbench.

Can I upgrade from ADX2TA to ADX2FDTA in the future?
The ADX2TA and ADX2FDTA are separate hardware units; frequency diversity is not field-upgradeable on the ADX2TA. If frequency diversity is required for your deployment, select the ADX2FDTA model at time of purchase.
