Shure AD2/B87C Handheld Wireless Microphone Transmitter

Product Overview

The Shure AD2/B87C is an Axient Digital handheld wireless transmitter with the Beta 87C cardioid condenser capsule, suited for presentation environments, corporate all-hands rooms, houses of worship, and conference room wireless deployments. The cardioid polar pattern of the Beta 87C is more forgiving of varied mic technique than a supercardioid, making it a practical choice for non-professional speakers and panel discussions. The AD2 platform delivers AES 256-bit encryption, High Density mode, and 184 MHz tuning range with dual battery support—AA or rechargeable—without the added cost of ShowLink remote control.

Product Description

The AD2/B87C enters the Axient Digital wireless platform at the AD tier, pairing the Beta 87C cardioid condenser capsule with Shure’s professional digital RF infrastructure. For commercial AV integrators, the cardioid pattern reduces the need for precise mic positioning and is typically preferred over supercardioid capsules for spoken-word presentations, town halls, and boardroom discussions where speakers are less experienced with handheld microphone technique. The transmitter supports both AA alkaline batteries and the optional SB900C rechargeable, giving event production teams flexibility for multi-day deployments without dedicated charging infrastructure. Frequency coordination and encryption settings are programmed via IR Sync from the receiver, and the transmitter operates in both Standard and High Density modes for system channel management.

Frequently Asked Questions

Why choose the Beta 87C over the Beta 87A for commercial AV?
The Beta 87C uses a standard cardioid polar pattern, which is more forgiving when speakers deviate from consistent mic positioning. In conference rooms, all-hands rooms, and panel discussions where speakers’ technique is unpredictable, the cardioid pattern reduces the chance of audio dropouts or tonal variation. The Beta 87A’s supercardioid pattern provides tighter off-axis rejection, which benefits feedback-prone environments with close monitor wedges.

Can the AD2/B87C use AA batteries in a venue without charging capability?
Yes. The AD2/B87C accepts 2× AA alkaline batteries providing approximately 8 hours at 10 mW, making it self-sufficient without dedicated charging stations. The optional SB900C rechargeable battery extends runtime to approximately 11 hours at 10 mW when charging is available.

What Axient Digital receivers are compatible?
AD4D, AD4Q, and ADX5D. Frequency bands between transmitter and receiver must match.

Does the AD2/B87C work in High Density mode for large channel count deployments?
Yes. High Density mode reduces channel spacing to 125 kHz, enabling more simultaneous channels within a given frequency band compared to Standard mode’s 350 kHz spacing. This is useful for large conference centers or multi-room AV deployments requiring 20+ simultaneous wireless channels.
