Shure ADX2TA/B87C=-X55 Digital Handheld Wireless Microphone Transmitter with Beta 87C Capsule (X55: 941 to 960 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2TA/B87C=-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. 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 X55 frequency band (941–960 MHz), it sits above the traditional UHF television spectrum, providing cleaner RF operation in spectrum-congested metro markets. Encryption-enabled transmission and ShowLink remote control deliver the security and system management capabilities required for professional commercial AV system integration.

Product Description

The ADX2TA/B87C=-X55 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 natural, open sound pickup wider than supercardioid designs, making it well-suited for broadcast presenters, panel discussions, and government proceedings where a more ambient, flattering sound pickup is preferred over tight isolation. 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. The X55 band (941–960 MHz) is particularly effective in dense urban RF environments where lower UHF bands face spectrum congestion from LTE and broadcast infrastructure. 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/B87C=-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 is the difference between the Beta 87C and Beta 87A capsule?
A: The Beta 87C uses a cardioid polar pattern with a wider, more natural sound pickup—preferred for broadcast presenters and panel discussions where an open sound is desired. The Beta 87A uses a tighter supercardioid pattern with better off-axis rejection, suited for situations requiring greater isolation from adjacent sound sources.

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: 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.
