Shure ADX2TA/B87A=-X55 Digital Handheld Wireless Microphone Transmitter with Beta 87A Capsule (X55: 941 to 960 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2TA/B87A=-X55 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. Equipped with the Beta 87A supercardioid condenser capsule, it delivers studio-quality wireless vocal reproduction suited for broadcast studios, boardrooms, and government facilities requiring transparent, detailed audio capture. Operating in the X55 frequency band (941–960 MHz), it operates above traditional UHF television spectrum, making it well-suited for RF-congested metro markets. ShowLink remote control and encryption-enabled transmission provide the network management and security capabilities required for professional commercial AV system integration.

Product Description

The ADX2TA/B87A=-X55 features a moisture-resistant, lightweight metal body with external docking contacts for charging via the Shure SBC240 two-bay or SBC840 eight-bay networked charger without removing the radome. The Beta 87A supercardioid condenser capsule provides improved off-axis rejection for controlled pickup in multi-presenter boardrooms, legislative chambers, and broadcast environments where ambient noise management is critical. Diversity ShowLink enables real-time remote adjustment of transmitter parameters through Wireless Workbench 6 software, allowing AV integrators to manage wireless systems without physical access to talent. High Density transmission mode accommodates maximum simultaneous channel count in spectrum-congested installations. Two SB920A lithium-ion rechargeable batteries are included, delivering up to 9 hours of continuous runtime.

Frequently Asked Questions

Q: Which Axient Digital receivers are compatible with the ADX2TA/B87A=-X55?
A: This transmitter is compatible with Axient Digital receivers operating in the X55 frequency band (941–960 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: Why would an AV integrator choose the X55 band for a government installation?
A: The X55 band (941–960 MHz) sits above the UHF television broadcast spectrum and avoids the 600–700 MHz range impacted by LTE spectrum reallocation, making it a strong choice for RF frequency coordination in spectrum-congested metro markets and dense government campuses.

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.
