Shure ADX2TA/B87A=-K54 Digital Handheld Wireless Microphone Transmitter with Beta 87A Capsule (K54: 606 to 663 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2TA/B87A=-K54 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 K54 frequency band (606–663 MHz) with up to 184 MHz of tuning range, it integrates into the Axient Digital wireless ecosystem with Standard and High Density transmission modes. Encryption-enabled transmission and ShowLink remote control make the ADX2TA/B87A the preferred choice for secure, high-fidelity commercial wireless microphone installations requiring TAA compliance.

Product Description

The ADX2TA/B87A=-K54 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, supporting high-rotation commercial deployments. 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—RF power, audio gain, mute state—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; Standard mode optimizes audio quality for smaller deployments. Two SB920A lithium-ion rechargeable batteries are included, delivering up to 9 hours of continuous runtime.
