Shure AD2/B87A Handheld Wireless Microphone Transmitter

Product Overview

The Shure AD2/B87A is an Axient Digital handheld wireless transmitter with the Beta 87A supercardioid condenser capsule, providing professional wireless audio performance for commercial meeting spaces, houses of worship, and broadcast applications. The AD2 platform delivers AES 256-bit encryption, High Density mode, and tuning up to 184 MHz at a lower cost than the ADX series, without ShowLink. Compatible with all Axient Digital receivers, the AD2/B87A is a direct-entry point into the Axient Digital wireless ecosystem for integrators who need condenser capsule performance with professional-grade RF infrastructure.

Product Description

The AD2/B87A pairs the AD2 transmitter body with the Beta 87A supercardioid condenser capsule, delivering the natural high-fidelity vocal reproduction of the Beta 87A within the Axient Digital RF platform. For AV integrators, this combination is well-suited to conference keynotes, corporate all-hands events, and broadcast interviews where clarity and off-axis rejection are priorities. The AD2 supports both Shure SB900C rechargeable batteries (up to 11 hours at 10 mW) and standard AA alkaline batteries (up to 8 hours), providing deployment flexibility for long events without access to charging infrastructure. Selectable 2/10/35 mW output power and both Standard and High Density operating modes ensure the transmitter can be configured for any channel density requirement. Capsules are field-swappable across the RPW-series cartridge lineup.

Frequently Asked Questions

What is the difference between the AD2/B87A and ADX2/B87A?
The ADX2/B87A includes ShowLink remote control for real-time Wireless Workbench integration and supports 40 mW maximum output power. The AD2/B87A does not have ShowLink but supports AA batteries in addition to the SB900C rechargeable, and is priced lower. Both use the same Beta 87A capsule and Axient Digital RF core.

Does the Beta 87A condenser capsule need phantom power?
No. The capsule is powered by the transmitter body itself—no external phantom power is required. The AD2 transmitter provides bias power to the capsule internally.

What receivers are compatible?
All Axient Digital receivers: AD4D, AD4Q, and ADX5D. Match the receiver frequency band to the transmitter band ordered.

Can I mix AD2 and ADX2 transmitters on the same Axient Digital receiver?
Yes. AD2 and ADX2 transmitters can operate simultaneously on the same Axient Digital receiver system. ShowLink functionality is only available for ADX2-series transmitters; AD2 transmitters appear in Wireless Workbench as standard monitored channels without remote control capability.

What warranty is included?
Shure provides a 2-year limited warranty. Contact Creation Networks for support.
