Shure ADX2TA/B87C=-G57 Digital Handheld Wireless Microphone Transmitter with Beta 87C Capsule (G57: 470 to 616 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2TA/B87C=-G57 is a TAA-compliant Axient Digital handheld wireless transmitter qualified for U.S. federal government procurement under GSA schedule contracts and federally funded AV projects. Fitted with the Beta 87C cardioid condenser capsule, it captures natural, full-frequency vocal audio with a wider pickup pattern suited for broadcast, government, and corporate presentation environments. Operating in the G57 frequency band (470–616 MHz) with up to 184 MHz of tuning range, it integrates into the Axient Digital wireless ecosystem with Standard and High Density transmission modes for scalable enterprise wireless deployment. Encryption-enabled transmission and ShowLink remote control make it the professional choice for compliant, secure commercial wireless audio installations.

Product Description

The ADX2TA/B87C=-G57 features a moisture-resistant, lightweight metal body with external docking contacts for charging via the Shure SBC240 or SBC840 networked charger without removing the radome. The Beta 87C cardioid condenser capsule provides a wider, more natural pickup pattern compared to supercardioid designs, making it well-suited for broadcast presenters, panel discussions, and government proceedings where a more open sound pickup is preferred. Diversity ShowLink enables real-time remote adjustment of transmitter RF and audio parameters through Wireless Workbench 6 software, supporting centralized wireless system management in multi-channel AV installations. High Density transmission mode increases simultaneous active channel capacity in spectrum-congested settings such as convention centers, broadcast facilities, and large-format government spaces. Two SB920A lithium-ion rechargeable batteries are included, delivering up to 9 hours of continuous runtime.

Frequently Asked Questions

Q: What is the difference between the Beta 87C and Beta 87A capsule on Axient Digital transmitters?
A: The Beta 87C uses a cardioid polar pattern, providing a wider, more natural sound pickup suited for broadcast presenters and panel applications. The Beta 87A uses a supercardioid pattern with tighter off-axis rejection, better suited for environments where isolation from nearby sound sources is critical, such as multi-presenter stages. Both deliver condenser-quality audio.

Q: Which Axient Digital receivers are compatible with the ADX2TA/B87C=-G57?
A: This transmitter is compatible with Axient Digital receivers operating in the G57 frequency band (470–616 MHz). Frequency band matching between transmitter and receiver is required for proper system operation.

Q: What does TAA compliance mean for procurement?
A: The TAA designation confirms this unit is manufactured in a Trade Agreements Act-compliant country, qualifying it for GSA Federal Supply Schedule purchases, military contracts, and federally funded AV projects with TAA requirements.

Q: Is Wireless Workbench software required to operate this transmitter?
A: Wireless Workbench 6 is not required for basic operation, but it enables ShowLink remote control, spectrum scanning, and multi-system monitoring. It is a free download from Shure and recommended for professional multi-channel deployments.

Q: What warranty does this product carry?
A: Shure provides a 2-year limited warranty on wireless microphone transmitters. Contact Creation Networks or Shure directly for warranty registration and authorized service information.
