Shure ADX2/K9N – Axient Digital Handheld Transmitter with KSM9 (Nickel)

Product Overview

The Shure ADX2/K9N is a professional Axient Digital handheld wireless transmitter designed for commercial AV deployments that demand reliable RF performance in dense-use environments. Equipped with the dual-diaphragm KSM9 condenser capsule in a nickel finish, this transmitter integrates with Axient Digital receivers for broadcast studios, houses of worship, government spaces, and large-venue AV installations. ShowLink remote control technology enables real-time parameter adjustment from the front-of-house position without touching the transmitter. Available in G57 (470–616 MHz), K54 (606–663 MHz), and X55 (941–960 MHz) frequency bands.

Product Description

The ADX2/K9N is built for AV system designers and integrators who need a dependable digital UHF handheld transmitter that performs under pressure. It operates on Shure's Axient Digital platform, delivering 2-ms latency and AES-256 encrypted audio transmission — critical for secure government and corporate meeting spaces. The KSM9 condenser capsule offers switchable cardioid and supercardioid polar patterns, giving operators the flexibility to adapt to different stage configurations and performer techniques without swapping hardware. A rugged aluminum housing and backlit LCD make the ADX2/K9N practical for demanding installation environments. The SB920 rechargeable lithium-ion battery provides up to 9 hours of runtime at medium power, while external charging contacts support docked charging via compatible Shure networked chargers. For a compatible receiver, see the Shure AD4DNP Two-Channel Digital Wireless Receiver. For a cost-effective Axient Digital handheld alternative, consider the Shure AD2/K8N Handheld Transmitter.

Key Features

• ShowLink Remote Control — Allows the FOH engineer to adjust gain, RF power, mute, and other transmitter parameters in real time from the booth without interrupting the event.
• KSM9 Condenser Capsule — Dual-diaphragm design with switchable cardioid and supercardioid polar patterns delivers precise vocal reproduction with minimal off-axis coloration and a 152 dB maximum SPL handling.
• AES-256 Encryption — Secure digital audio transmission protects against eavesdropping in government, corporate, and sensitive commercial AV environments.
• 146 MHz Tuning Range — Wide tuning within the G57 band allows system designers to coordinate large channel counts and avoid interference in congested RF environments.
• Selectable RF Output — 2/10/50 mW output power lets installers balance transmission range against RF spectral density, supporting up to 100 m (330 ft) line of sight at 10 mW.
• Up to 9 Hours Battery Life — SB920 rechargeable lithium-ion battery with precision time-remaining metering ensures reliable operation through full-day events and multi-session installations.
• IR Sync — One-touch infrared synchronization with compatible Axient Digital receivers accelerates deployment and frequency coordination during installation setup.
• Automatic Gain Adjustment — Onboard auto-gain reduces setup time for FOH engineers managing multiple transmitters across a complex wireless system.
• Interchangeable Capsule Design — The capsule can be swapped for other compatible Shure wireless capsules (SM58, Beta 87A, Beta 87C, KSM8, VP68, and others) to adapt the transmitter to different applications.
• Backlit LCD Display — Provides at-a-glance access to frequency, group/channel, mute/lock status, RF output level, and remaining battery life during live event operation.
• High-Density Mode — Supports maximum channel count in spectrum-limited venues alongside standard mode for mixed system configurations.
• Lightweight Aluminum Housing — At 338 g (11.9 oz) without battery, the ADX2/K9N is built for continuous commercial use on touring and installed AV systems.

Typical Applications

• House of worship with multiple wireless channels and shared RF coordination requirements
• Boardroom and government space deployments requiring encrypted wireless audio transmission
• Conference room and all-hands room AV systems managed remotely via ShowLink
• Broadcast studio and auditorium productions requiring low-latency digital wireless performance
• Multi-purpose room and training room installations where interchangeable capsule flexibility is needed

Frequently Asked Questions

Which Axient Digital receivers are compatible with the ADX2/K9N?
The ADX2/K9N is compatible with all Axient Digital series receivers, including the AD4D dual-channel and AD4Q four-channel rack-mount receivers. Frequency bands must match between transmitter and receiver — verify G57, K54, or X55 when ordering.

Does the ADX2/K9N support Frequency Diversity?
No. The ADX2/K9N is a single-carrier transmitter. For mission-critical applications requiring simultaneous dual-frequency transmission, the ADX2FD/K9N model adds Frequency Diversity. Both are compatible with the same Axient Digital receivers.

Can the capsule be replaced in the field?
Yes. The interchangeable capsule design allows field replacement with compatible Shure wireless capsules including SM58, Beta 87A, Beta 87C, KSM8, KSM9HS, and VP68. No tools are required — unscrew the existing capsule and thread on a replacement.

How is ShowLink integrated into a commercial AV system?
ShowLink requires an AD610 ShowLink access point connected to the same network as Shure Wireless Workbench 6 (WWB6) software. Once configured, the operator can remotely adjust gain, RF output, mute, and frequency on the ADX2/K9N from front-of-house — without accessing the transmitter physically.

What is the warranty on the ADX2/K9N?
Shure provides a limited 2-year manufacturer warranty. Creation Networks supports warranty claims and can assist with technical questions for commercial AV deployments.
