Shure AD2TA/B58=-X55 – Axient Digital Handheld Transmitter, Beta 58A, X55 (TAA)

Product Overview

The Shure AD2/B58 Axient Digital handheld wireless microphone transmitter (AD2TA/B58=-X55) operates in the X55 band (941–960 MHz) with a built-in Beta 58A dynamic supercardioid capsule and TAA compliance. Operating above the standard UHF TV broadcast spectrum, the X55 band provides spectrum access in deployments where lower-UHF frequencies are congested or locally restricted. AES-256 encryption, High Density mode, and Wireless Workbench 6 integration make this a professional-grade wireless handheld for commercial AV installation, broadcast, government audio, and live sound reinforcement. The interchangeable capsule design allows the transmitter body to be repurposed across applications with a simple capsule swap. See also the Shure RPW122 Beta 87C Wireless Replacement Capsule for condenser upgrade options compatible with this transmitter.

Product Description

The AD2TA/B58=-X55 brings the full performance of the Axient Digital wireless platform to the X55 band (941–960 MHz), providing commercial AV system designers with a spectrum option above the primary UHF broadcast congestion. The Beta 58A dynamic supercardioid capsule is tailored for close-mic vocal applications: its brightened midrange, controlled proximity effect, supercardioid polar pattern, and high-SPL handling (up to 147 dB) make it a reliable choice for live sound reinforcement in commercial and performance spaces. The transmitter body supports selectable RF output power, Automatic Gain Control, frequency/power lockout, and full Wireless Workbench 6 management. Note: verify local regulatory authorization for 941–960 MHz operation before deployment, as frequency use in this range is subject to market-specific licensing requirements.

Key Features

• Beta 58A Dynamic Supercardioid Capsule — Brightened midrange and bass roll-off for close-mic vocals with high-SPL handling (147 dB max), neodymium magnet for high signal-to-noise output, and supercardioid polar pattern for strong off-axis rejection and gain-before-feedback performance.
• X55 Band Operation (941–960 MHz) — Operates above the standard UHF TV broadcast window, providing spectrum access in markets where lower-UHF bands are congested or locally restricted. Verify local regulatory authorization before deployment.
• Interchangeable Capsule Design — The Beta 58A capsule is field-replaceable with any Shure RPW-series wireless capsule (Beta 87A, Beta 87C, KSM8, KSM9, SM58, VP68, and others), allowing one transmitter body to support multiple AV applications.
• High Density Mode — Increases simultaneous channel count for commercial AV deployments requiring many concurrent wireless channels in a constrained spectrum window.
• AES-256 Encryption — Standard on every unit for secure audio transmission in government, enterprise, and sensitive AV environments.
• Selectable RF Output Power (2/10/35 mW) — Three levels provide control over the tradeoff between transmission range (up to 100 m line-of-sight) and channel density.
• Automatic Gain Control — Manages input levels in real time for consistent signal quality across different performers and vocal dynamics without manual adjustments.
• Rechargeable Battery Option — Accepts the optional Shure SB900A rechargeable Li-ion battery for up to 9 hours runtime, with networked charging via SBC220 or SBC840 chargers.
• IR Sync — One-touch infrared synchronization with Axient Digital receivers accelerates channel assignment in multi-channel commercial AV installations.
• Wireless Workbench 6 Compatible — Centralized RF coordination, spectrum analysis, real-time monitoring, and remote configuration for commercial-grade wireless deployments.
• Durable Aluminum Housing — Moisture-resistant (340 g / 12 oz without batteries) for regular professional use.
• TAA-Compliant — Qualifies for federal government procurement under GSA schedules and Trade Agreements Act contract vehicles.

Typical Applications

• Government and federal audio installations requiring TAA-compliant wireless microphones with AES-256 encryption in the X55 band
• Commercial AV installations in markets where the 941–960 MHz range provides better spectrum access than lower-UHF bands
• Broadcast studio and on-camera wireless microphone applications configured for 900+ MHz band operation
• House of worship and commercial auditorium vocal reinforcement with encrypted wireless infrastructure
• All-hands room and corporate presentation environments requiring secure wireless handheld microphones
• Multi-purpose room and training facility deployments using X55 band for spectrum diversity across multiple wireless systems
• Commercial meeting space AV systems managed via Wireless Workbench 6

Technical Specifications

Frequently Asked Questions

Is the 941–960 MHz band legal to use in the United States?
Operation in the 941–960 MHz range is subject to FCC regulation and may require frequency coordination or licensing depending on specific frequencies and power levels. Always verify local regulatory compliance and current FCC frequency allocations before deploying equipment in this band. Creation Networks recommends working with an RF coordinator for X55 band deployments.

What capsules can be swapped into the AD2 transmitter body?
The AD2 accepts all Shure RPW-series wireless capsules: RPW118 (Beta 58A), RPW120 (Beta 87A), RPW122 (Beta 87C), RPW112 (SM58), RPW124 (VP68 omnidirectional), RPW170/RPW174 (KSM8), RPW184 (KSM9), and others. Swaps require no tools.

What Axient Digital receiver do I need for the X55 band?
Use an Axient Digital receiver (AD4D or AD4Q) configured for the X55 band (941–960 MHz). Frequency bands must match between transmitter and receiver. The AD2 is not compatible with ULX-D, SLX-D, or BLX series receivers.

Is the AD2TA/B58=-X55 TAA-compliant?
Yes. This unit is TAA-compliant and eligible for federal procurement under GSA schedules and government contract vehicles requiring Trade Agreements Act compliance.

What warranty does the Shure AD2 carry?
Shure provides a limited 2-year manufacturer warranty on the AD2 handheld transmitter. Contact Creation Networks for warranty service and support inquiries.
