AD2/K11B Handheld Transmitter

Shure AD2/K11B Digital Handheld Wireless Microphone Transmitter – Black

The AD2/K11B is a professional-grade handheld digital wireless transmitter designed for use with Shure's Axient Digital series receivers. Outfitted with the KSM11B condenser capsule, it features a cardioid pickup pattern that delivers focused audio capture with excellent rejection of ambient sound—ideal for vocal performances in demanding environments.

The capsule includes a durable aluminum and steel grille, a built-in three-layer pop filter to minimize plosives and breath noise, and an integrated shockmount that helps reduce handling noise during use. Its tight cardioid pattern provides strong feedback resistance and natural sound reproduction with minimal coloration.

Key performance features include:

• Operation across a broad 146 MHz UHF bandwidth

• Selectable RF output power of 2, 10, or 35 mW

• Transmission range of up to 330 feet

• Power options: up to 8 hours on two AA batteries or up to 9 hours with the SB900A rechargeable battery (sold separately)

Housed in a lightweight, moisture-resistant aluminum chassis, the AD2/K11B also includes AES 256-bit encryption for secure wireless transmission and supports advanced charging options, making it an excellent choice for professional touring, broadcast, or corporate AV applications.
