Shure AD2TA/B87C=-G57 – Axient Digital Handheld Transmitter, Beta 87C, G57 (TAA)

Product Overview

The Shure AD2/B87C Axient Digital handheld wireless microphone transmitter (AD2TA/B87C=-G57) pairs the Beta 87C cardioid condenser capsule with the Axient Digital wireless platform in the G57 band (470–616 MHz), with TAA compliance. The Beta 87C delivers a smooth, extended frequency response and cardioid polar pattern optimized for vocal performers, corporate presenters, and broadcast talent who need consistent coverage with natural-sounding audio. AES-256 encryption, High Density mode, and Wireless Workbench 6 integration make this a commercial-grade component for AV integrators deploying professional wireless microphone systems in corporate spaces, government facilities, and broadcast environments. The interchangeable capsule design means the transmitter body can serve other applications by swapping in a different RPW-series capsule, such as the Shure RPW122 Beta 87C Replacement Capsule when the original needs to be replaced.

Product Description

The AD2TA/B87C=-G57 is a professional Axient Digital handheld transmitter for commercial AV system integration featuring the Beta 87C cardioid condenser capsule. The Beta 87C cardioid pattern offers wider coverage than the supercardioid Beta 87A, making it better suited for presenters who may not maintain precise microphone positioning and for applications where a slightly wider pickup area is beneficial. Its smooth frequency response with extended high end delivers clarity and naturalness for corporate AV presentations, broadcast interviews, and vocal reinforcement in commercial meeting spaces. With selectable RF output power (2/10/35 mW), 146 MHz of ultrawide UHF tuning, Automatic Gain Control, and frequency/power lockout, the AD2/B87C provides the RF performance and operational control required for professional commercial AV deployments. Wireless Workbench 6 enables centralized spectrum management and remote monitoring. TAA-compliant for government procurement.

Key Features

• Beta 87C Cardioid Condenser Capsule — Smooth frequency response with extended high end and a cardioid polar pattern providing wider coverage than supercardioid designs, ideal for corporate presenters, broadcast talent, and vocal applications where precise mic positioning may vary.
• Cardioid Polar Pattern — Wider pickup area compared to the Beta 87A supercardioid, providing more forgiving coverage for moving presenters while still rejecting rear-facing sound sources in commercial AV environments.
• Interchangeable Capsule Design — The Beta 87C capsule is field-replaceable with any Shure RPW-series capsule (Beta 87A, Beta 58A, KSM8, KSM9, SM58, VP68, and others), allowing the transmitter body to serve multiple applications without replacement.
• G57 Band Operation (470–616 MHz) — 146 MHz ultrawide UHF tuning provides wide frequency agility for interference management in commercial AV environments.
• High Density Mode — Enables high-density simultaneous channel deployment for large commercial AV, broadcast, government, and auditorium wireless systems.
• AES-256 Encryption — Standard on every unit for secure audio transmission in government and enterprise AV deployments.
• Selectable RF Output Power (2/10/35 mW) — Three levels enable control over the range-vs-channel density tradeoff for any commercial installation scenario.
• Automatic Gain Control — Manages input levels in real time across different presenters and performers for consistent signal quality without manual adjustments.
• Rechargeable Battery Option — Optional Shure SB900A rechargeable Li-ion battery for up to 9 hours runtime with networked docked charging.
• IR Sync — One-touch infrared synchronization with Axient Digital receivers for rapid multi-channel deployment.
• Wireless Workbench 6 Compatible — Enterprise RF coordination platform for centralized spectrum management and remote monitoring.
• TAA-Compliant — Eligible for federal government procurement under GSA schedules and Trade Agreements Act contract vehicles.

Typical Applications

• Corporate boardroom and conference room wireless presentations where condenser microphone quality and wide cardioid coverage are preferred
• Broadcast studio handheld wireless applications requiring smooth, natural-sounding condenser audio with AES-256 encryption
• Government facilities requiring TAA-compliant wireless audio for presentations and hearings
• Commercial auditorium and performing arts vocal reinforcement where a cardioid pattern provides more flexible coverage than supercardioid alternatives
• All-hands room and commercial meeting space AV systems with multiple simultaneous presenter wireless microphones
• House of worship spoken word and lead vocal applications where condenser quality and cardioid coverage are preferred
• Training room installations managed via Wireless Workbench 6

Frequently Asked Questions

What is the difference between the Beta 87C (cardioid) and Beta 87A (supercardioid)?
The Beta 87C has a cardioid polar pattern with a wider pickup area, providing more forgiving coverage for presenters and performers who may not maintain precise microphone positioning. The Beta 87A has a supercardioid pattern with tighter off-axis rejection, which is better for environments with higher ambient noise or when maximum isolation from off-axis sound sources is needed. For corporate presentations and broadcast interviews in controlled environments, the Beta 87C cardioid pattern is often preferred. For live sound reinforcement in louder environments, the Beta 87A supercardioid provides better feedback rejection.

Can the Beta 87C capsule be replaced with other RPW-series capsules?
Yes. The AD2 transmitter body accepts all Shure RPW-series wireless capsules. The RPW122 (replacement Beta 87C) is available as a spare. Other options include the RPW120 (Beta 87A), RPW118 (Beta 58A), RPW112 (SM58), RPW124 (VP68 omnidirectional), RPW170/RPW174 (KSM8), and RPW184 (KSM9).

Is the AD2/B87C compatible with Axient Digital receivers?
Yes. The AD2 is compatible with all Axient Digital receivers (AD4D dual-channel, AD4Q four-channel) in matching frequency bands. This G57 unit requires an Axient Digital receiver configured for the G57 band (470–616 MHz). It is not compatible with ULX-D, SLX-D, or BLX receivers.

Is the AD2TA/B87C=-G57 TAA-compliant?
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 on the AD2 handheld transmitter. Contact Creation Networks for warranty service and support.
