Shure AD2Overview

TheShure AD2/B87Ais a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers.

The AD2/B87A comes equipped with the Beta 87A condenser capsule designed to withstand extreme sound pressure levels, while still delivering a remarkably smooth frequency response for vocal performers and presenters. The capsule features a supercardioid polar pattern that offers excellent rejection of off-axis background noise, helping to reduce feedback.

The transmitter operates in a single 146 MHz ultrawide UHF bandwidth with selectable 2/10/35mW RF output power and a transmission range up to 330′. It provides up to 8 hours of operation on two AA batteries and up to 9 hours with an SB900A lithium-ion rechargeable battery (available separately).

With a durable, moisture-resistant, lightweight aluminum case, the AD2/B87A transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement applications.

Interchangeable Design with Beta 87A Capsule

  • The Beta 87A supercardioid condenser capsule handles SPL levels up to 140 dB and offers a smooth frequency response with a gradual presence rise and controlled proximity effect tailored for vocals.
  • The interchangeable capsule design allows you to replace the Beta 87A capsule with a Shure capsule thats ideal for your application and simply screw it onto the transmitterincluding KSM9, KSM8, SM58, VP68, Beta 87C capsules, and more.
