Shure AD2/K9HSN – Axient Digital Handheld Wireless Transmitter with KSM9HS, Nickel

Product Overview

The Shure AD2/K9HSN is an Axient Digital handheld wireless microphone transmitter featuring the KSM9HS condenser capsule in a nickel metal body. Built for professional live sound, broadcast, and commercial AV deployments requiring the highest RF performance and audio quality, the AD2 Axient Digital wireless transmitter delivers wide tuning up to 184 MHz, High Density mode, and AES 256 encryption. Paired with an Axient Digital receiver, it provides the transparency and RF resilience required for critical applications in competitive RF environments.

Product Description

The KSM9HS capsule on the AD2/K9HSN is optimized for demanding vocal applications where the KSM9HS's focused polar pattern delivers enhanced feedback rejection in high-SPL stage environments—making it well-suited for live performance, large auditoriums, and broadcast applications. The all-metal nickel body is constructed for durability in touring and fixed-installation commercial AV use. Two transmission modes—Standard for maximum coverage and High Density for maximum channel count—give system designers flexibility for large venues or multi-channel corporate events. Rechargeable Shure lithium-ion batteries with dockable charging eliminate battery management complexity in multi-channel deployments. For the compatible two-channel Axient Digital receiver, see the Shure AD4DUS Two-Channel Digital Wireless Receiver. Also available in black finish with KSM9 capsule: Shure AD2/K9B.

Frequently Asked Questions

What is the difference between the KSM9 and KSM9HS capsules?
The KSM9 (used in the AD2/K9B) is a dual-diaphragm condenser with switchable cardioid and supercardioid polar patterns. The KSM9HS (used in this AD2/K9HSN) offers a focused polar response optimized for higher feedback rejection, suited for louder stage environments and larger auditoriums.

What receivers are compatible with the AD2/K9HSN?
The AD2/K9HSN is compatible with all Axient Digital receivers—including the AD4DUS dual-channel and AD4Q quad-channel receivers—in the matching frequency band (G57 for this variant).

Can the capsule be swapped on the AD2/K9HSN?
Yes. The AD2 accepts RPW series wireless replacement cartridges, allowing the capsule to be changed without replacing the transmitter body. Note that capsule availability varies by finish (nickel vs. black) for some cartridge models.

Does the AD2/K9HSN work with Wireless Workbench 6?
Yes. When paired with a networked Axient Digital receiver, the AD2/K9HSN can be monitored via WWB6 for RF level, battery status, and gain control.

What charging solutions are compatible?
The AD2/K9HSN is compatible with Shure's SB900B and SB900C lithium-ion batteries, and the SBC200, SBC220, SBC800, and SBRC charging solutions for streamlined battery management in multi-channel deployments.
