Shure ADX2TA/K8B=-X55 Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (X55: 941 to 960 MHz, Black) (TAA-Compliant)

Product Overview

The Shure ADX2TA/K8B=-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 KSM8 dual-diaphragm cardioid dynamic capsule in black finish, it delivers transparent, natural vocal reproduction suited for broadcast studios, government facilities, and large-venue commercial AV installations. Operating in the X55 frequency band (941–960 MHz), it sits above traditional UHF television spectrum, providing cleaner RF operation in spectrum-congested metro markets where LTE and broadcast infrastructure compete for lower UHF bandwidth. ShowLink remote control and encryption-enabled transmission deliver the enterprise management and security capabilities required for compliant commercial wireless audio deployments.

Product Description

The ADX2TA/K8B=-X55 features a moisture-resistant, lightweight metal body in black finish with external docking contacts for charging via the Shure SBC240 or SBC840 networked charger without removing the radome. The KSM8 dual-diaphragm dynamic capsule is engineered for transparent, flat vocal response across the critical speech frequency range, making it the choice for discerning AV integrators specifying wireless systems for broadcast studios, auditoriums, and large government facilities where natural, uncolored dynamic microphone performance is the priority. The X55 band (941–960 MHz) is particularly effective in dense urban environments and government campuses where the lower UHF bands face spectrum pressure. Diversity ShowLink enables real-time remote adjustment of transmitter parameters through Wireless Workbench 6 software, supporting centralized management without physical access to talent. Two SB920A lithium-ion rechargeable batteries are included, delivering up to 9 hours of continuous runtime. For a comparable Shure digital wireless handheld, see the Shure ULXD2/B58 Digital Handheld Wireless Transmitter.

Key Features

• TAA Compliance — Designated TA variant confirms Trade Agreements Act compliance for GSA schedules, federal procurement, and government-funded commercial AV installations.
• KSM8 Dual-Diaphragm Cardioid Dynamic Capsule (Black) — Delivers transparent, natural vocal reproduction with controlled proximity effect, suited for broadcast, government, and professional live performance environments requiring uncolored audio.
• Diversity ShowLink Remote Control — Enables real-time remote adjustment of RF power, audio gain, and mute state from Wireless Workbench 6 without physical access to the transmitter or talent during live events.
• High Density Transmission Mode — Increases simultaneous active wireless channel count in spectrum-limited environments, supporting large-scale enterprise AV deployments in government and corporate facilities.
• Encryption-Enabled Transmission — Secures wireless audio transport for government, defense, and enterprise AV applications requiring protected RF communication.

Frequently Asked Questions

Q: Which Axient Digital receivers are compatible with the ADX2TA/K8B=-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: Why choose the X55 band for a government or metro AV installation?
A: The X55 band (941–960 MHz) operates above traditional UHF broadcast spectrum and avoids the 600–700 MHz range affected by LTE spectrum reallocation, making it a strong choice for RF frequency coordination in spectrum-congested metro markets and dense government campuses where lower UHF bands face heavy competition.

Q: What makes the KSM8 capsule stand out compared to other ADX2TA capsule options?
A: The KSM8 dual-diaphragm cardioid dynamic is engineered for transparent, uncolored vocal response—bridging the gap between traditional dynamics and condensers. It is suited for applications where natural, flat audio capture is the priority rather than the elevated presence of condenser capsules or the high-SPL focus of the Beta 58A.

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.
