Shure ADX2TA/B58=-K54 Digital Handheld Wireless Microphone Transmitter with Beta 58A Capsule (K54: 606 to 663 MHz) (TAA-Compliant)

Product Overview

The Shure ADX2TA/B58=-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. Fitted with the Beta 58A supercardioid dynamic capsule, it delivers reliable wireless vocal audio in high-interference commercial environments, operating in the K54 frequency band (606–663 MHz). It integrates into the Axient Digital wireless ecosystem with support for Standard and High Density transmission modes, enabling large-scale multi-channel deployments in government facilities, corporate all-hands rooms, and broadcast studios. Encryption-enabled transmission and ShowLink remote control make it the professional standard for compliant commercial wireless microphone installations.

Product Description

The ADX2TA/B58=-K54 features a moisture-resistant, lightweight metal enclosure 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 deployment environments. Diversity ShowLink provides real-time remote control of transmitter parameters including RF power, audio gain, and mute state through Wireless Workbench 6, eliminating the need for physical access to the presenter during live events or government proceedings. High Density transmission mode increases simultaneous active channel capacity in spectrum-congested settings such as convention centers and legislative chambers, while Standard mode prioritizes audio quality in smaller deployments. Two SB920A lithium-ion rechargeable batteries are included with up to 9 hours of continuous runtime per charge. The TAA designation confirms this unit is manufactured in a Trade Agreements Act-compliant country, a requirement for federally funded AV projects and government contractor installations. For a comparable Shure digital wireless handheld, see the Shure ULXD2/B58 Digital Handheld Wireless Transmitter.
