Shure ADX2/K9HSB Digital Handheld Wireless Microphone Transmitter with KSM9HS Capsule (Black)

Product Overview

The Shure ADX2/K9HSB is a premium Axient Digital handheld wireless transmitter fitted with the KSM9HS dual-pattern condenser capsule in black finish, designed for professional broadcast, performing arts, and commercial AV applications where precise polar pattern control is required. The KSM9HS offers selectable hypercardioid and subcardioid patterns—providing tighter rejection in one mode and wider pickup in the other—making it versatile across diverse deployment scenarios. ShowLink remote control, AES 256-bit encryption, 184 MHz tuning, and High Density mode are standard features of the ADX2 platform.

Product Description

The ADX2/K9HSB pairs the ADX2 transmitter body with the KSM9HS condenser capsule, Shure’s hypercardioid/subcardioid dual-pattern variant of the KSM9. For AV system designers, the KSM9HS’s hypercardioid option delivers the tightest off-axis rejection in Shure’s RPW capsule lineup, suited for stage environments with monitor wedges and significant ambient noise. The subcardioid option provides a wider pattern for conference and broadcast setups where ambient rejection is less critical than coverage area. The ADX2 transmitter body adds ShowLink for real-time Wireless Workbench management, selectable 40 mW maximum output for large-venue deployments, and the SB920A rechargeable battery (included) for up to 9 hours runtime at 10 mW. At $2,781, the ADX2/K9HSB is Shure’s highest-tier handheld configuration, combining maximum capsule flexibility with the full ADX remote management platform.

Key Features

• KSM9HS Dual-Pattern Condenser Capsule (Black) — Selectable hypercardioid and subcardioid polar patterns in a single capsule—hypercardioid for maximum ambient rejection on stage, subcardioid for wide coverage in conference and broadcast environments.
• ShowLink Remote Control — Real-time wireless management via IEEE 802.15.4 diversity link integrated with Wireless Workbench for frequency coordination, power adjustment, and muting from the front-of-house position.
• 184 MHz Tuning Range — Professional-grade frequency agility for deployment in any commercial RF environment.
• AES 256-Bit Encryption — Secure audio for government, broadcast, and executive conference deployments.
• High Density Mode — 125 kHz channel spacing enables maximum simultaneous channel count in spectrum-limited environments.
• Selectable RF Output: 2/10/40 mW — Full power range for both high-density close-range systems and extended-range large-venue deployments.

Frequently Asked Questions

What is the difference between the KSM9 and KSM9HS capsules?
The KSM9 (RPW184/RPW188) offers selectable cardioid and supercardioid patterns. The KSM9HS (RPW186/RPW190) offers selectable hypercardioid and subcardioid patterns—providing a tighter rejection angle than the KSM9’s supercardioid in one mode, and a wider pattern than cardioid in the other. Choose the KSM9HS when maximum off-axis rejection is required (e.g., stage with side-fill monitors) or when the widest possible coverage is needed for a single-mic setup.

Is the ADX2/K9HSB available in nickel finish?
Yes. The ADX2/K9HSN uses the nickel-finish KSM9HS capsule (RPW190). Performance is identical; the difference is cosmetic.

What receivers are compatible?
All Axient Digital receivers: AD4D, AD4Q, and ADX5D. The receiver frequency band must match the transmitter band (this SKU: G57, 470–616 MHz).

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