Shure AD2TA/B87A=-G57 – Axient Digital Handheld Transmitter, Beta 87A, G57 (TAA)

Product Overview

The Shure AD2/B87A Axient Digital handheld wireless microphone transmitter (AD2TA/B87A=-G57) combines the Beta 87A condenser supercardioid capsule with the full performance of the Axient Digital platform in the G57 band (470–616 MHz), with TAA compliance. Designed for corporate AV presentations, broadcast applications, commercial meeting spaces, and professional vocal reinforcement environments where condenser microphone quality is required, the AD2/B87A delivers smooth frequency response with gradual presence rise, 140 dB max SPL handling, and a supercardioid polar pattern for strong off-axis rejection. AES-256 encryption, High Density mode, and Wireless Workbench 6 integration provide the commercial-grade wireless management required by professional AV integrators and IT facilities managers. The transmitter body accepts any Shure RPW-series capsule, including the RPW122 Beta 87C Cardioid Condenser Capsule, for application flexibility across commercial AV deployments.

Product Description

The AD2TA/B87A=-G57 is a professional wireless handheld transmitter for commercial AV integration, featuring the Beta 87A condenser capsule — a supercardioid condenser microphone element optimized for vocal performance in presentation and broadcast environments. The Beta 87A delivers a smooth, extended frequency response with gradual presence rise that adds clarity and intelligibility to spoken word and singing in commercial meeting rooms, corporate all-hands events, broadcast studios, and government facilities. Its supercardioid polar pattern provides strong rejection of off-axis ambient sound, reducing feedback risk in acoustically challenging commercial spaces. With selectable RF output power (2/10/35 mW), Automatic Gain Control, frequency/power lockout, and full Wireless Workbench 6 compatibility, the AD2/B87A gives AV system designers complete control over wireless performance across commercial-grade deployments. TAA-compliant for federal and government agency procurement.

Key Features

• Beta 87A Condenser Supercardioid Capsule — Delivers smooth frequency response with gradual presence rise and extended high end, tailored for vocal performance and speech intelligibility in corporate AV, broadcast, and commercial meeting environments. Handles up to 140 dB SPL.
• Supercardioid Polar Pattern — Strong off-axis rejection minimizes feedback risk and isolates the primary source from ambient sound in commercial AV spaces, auditoriums, and broadcast environments.
• Interchangeable Capsule Design — The Beta 87A capsule is field-replaceable with any Shure RPW-series wireless capsule (Beta 87C, Beta 58A, KSM8, KSM9, SM58, VP68, and others), enabling a single transmitter body to serve multiple commercial AV applications.
• G57 Band Operation (470–616 MHz) — Operates across 146 MHz of ultrawide UHF tuning in the standard professional wireless range, with excellent frequency agility for interference management in complex commercial AV environments.
• High Density Mode — Supports high-density simultaneous channel deployment for large commercial AV installations, broadcast studios, government facilities, and houses of worship.
• AES-256 Encryption — Standard on every unit for secure audio transmission in government, enterprise, and legal AV environments without additional licensing.
• Selectable RF Output Power (2/10/35 mW) — Three power levels enable precise control over the transmission range vs. channel density tradeoff for any commercial installation.
• Automatic Gain Control — Real-time input level management maintains consistent signal quality across presenters and performers with varying vocal dynamics.
• 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 — Infrared one-touch synchronization with Axient Digital receivers reduces multi-channel setup time in commercial AV installations.
• Wireless Workbench 6 Compatible — Enterprise RF management with centralized spectrum coordination, battery monitoring, remote configuration, and multi-site deployment management.
• TAA-Compliant — Direct eligibility for federal government procurement under GSA schedules and Trade Agreements Act contract vehicles.

Frequently Asked Questions

When should I choose the Beta 87A over the Beta 58A or Beta 87C?
The Beta 87A is a condenser supercardioid capsule optimized for vocal performance with smooth, extended frequency response and a gradual presence rise that adds intelligibility and airiness to spoken word and singing. Choose it over the Beta 58A (dynamic) when recording-quality condenser audio is preferred and the environment has controlled SPL levels. Choose the Beta 87A over the Beta 87C when stronger off-axis rejection is needed — the supercardioid pattern of the Beta 87A rejects more side noise than the cardioid Beta 87C, making it preferable in higher-ambient-noise commercial environments.

What capsules are compatible with the AD2 transmitter body?
The AD2 accepts all Shure RPW-series capsules: RPW120 (Beta 87A), RPW122 (Beta 87C), RPW118 (Beta 58A), RPW112 (SM58), RPW124 (VP68 omnidirectional), RPW170/RPW174 (KSM8), RPW184 (KSM9), and others. Capsules swap without tools in the field.

Is the AD2/B87A compatible with Axient Digital receivers?
Yes. The AD2 is compatible with all Axient Digital receivers (AD4D, AD4Q) in matching frequency bands. This unit operates in the G57 band (470–616 MHz). It is not compatible with ULX-D or SLX-D receivers.

Is the AD2TA/B87A=-G57 TAA-compliant for government purchasing?
Yes. This unit is TAA-compliant and eligible for procurement under GSA schedules and federal contract vehicles requiring Trade Agreements Act compliance.

What warranty does the Shure AD2 carry?
Shure provides a limited 2-year manufacturer warranty. Contact Creation Networks for warranty and support services.
