Shure AD2/K9HSB Handheld Wireless Microphone Transmitter (Black)

Product Overview

The Shure AD2/K9HSB is an Axient Digital handheld wireless transmitter with the KSM9HS dual-pattern condenser capsule in black finish, providing professional wireless audio performance for commercial AV, broadcast, and live reinforcement applications. The KSM9HS’s selectable hypercardioid and subcardioid polar patterns give AV system designers exceptional flexibility in managing off-axis rejection and coverage area. The AD2 platform delivers AES 256-bit encryption, High Density mode, and tuning up to 184 MHz with dual battery support—without ShowLink remote control—at a lower price point than the ADX2 tier.

Product Description

The AD2/K9HSB pairs the AD2 transmitter with the KSM9HS condenser capsule (RPW186, black), offering the same dual-pattern KSM9HS acoustic performance as the ADX2/K9HSB at the standard AD2 price tier—without ShowLink. For commercial AV integrators where remote transmitter management is not required, the AD2/K9HSB provides access to the KSM9HS’s hypercardioid and subcardioid pattern options within the Axient Digital ecosystem at a meaningful cost reduction versus the ADX2. The transmitter supports both Shure SB900C rechargeable batteries (up to 11 hours at 10 mW) and 2× AA alkaline batteries (up to 8 hours), offering maximum power flexibility for multi-day events. Selectable 2/10/35 mW RF output and both Standard and High Density operating modes give the integrator full channel-density management capability.

Frequently Asked Questions

What is the difference between the AD2/K9HSB and ADX2/K9HSB?
Both use the same KSM9HS black capsule on an Axient Digital transmitter body. The ADX2/K9HSB adds ShowLink remote control (real-time Wireless Workbench management) and supports 40 mW maximum output. The AD2/K9HSB does not include ShowLink but supports AA batteries in addition to the SB900C rechargeable, and is priced lower. Both deliver the same core Axient Digital RF performance.

Can AA batteries be used?
Yes. The AD2/K9HSB accepts 2× AA alkaline batteries (approximately 8 hours at 10 mW) or the optional Shure SB900C rechargeable (up to 11 hours at 10 mW).

What receivers are compatible?
All Axient Digital receivers: AD4D, AD4Q, and ADX5D. Receiver frequency band must match the transmitter band ordered.

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