Shure ADX2/K8N Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (Nickel)

Product Overview

The Shure ADX2/K8N is a premium Axient Digital handheld wireless transmitter fitted with the KSM8 dual-diaphragm dynamic capsule in nickel finish, engineered for commercial AV installations and live performance where a dynamic capsule’s SPL handling and consistent tone are required. The KSM8’s innovative dual-diaphragm design delivers a flatter frequency response curve than traditional dynamic capsules, making it suitable for both high-SPL stage environments and spoken-word conference deployments. ShowLink remote control, 184 MHz tuning range, and AES 256-bit encryption are standard features of the ADX series platform.

Product Description

The ADX2/K8N pairs the ADX2 transmitter platform with Shure’s KSM8 Dual-Diaphragm dynamic capsule in nickel finish. The KSM8 uses a secondary floating diaphragm to reduce the proximity effect and smooth the frequency response compared to conventional dynamic capsules, giving AV engineers more predictable results across varying mic technique and source distance. This is particularly valuable in multi-presenter conference applications, houses of worship with untrained speakers, and broadcast environments. The ADX series transmitter body adds ShowLink remote management and AES 256-bit encryption to this capsule combination. At $2,657, the ADX2/K8N targets professional integrators who need the KSM8’s acoustic characteristics with the RF performance and network manageability of the Axient Digital platform. The nickel finish matches the ADX2/K8N body for a consistent aesthetic on stage or in front-of-house environments.

Key Features

• KSM8 Dual-Diaphragm Dynamic Capsule (Nickel) — Shure’s proprietary floating dual-diaphragm design reduces proximity effect and delivers a flatter frequency response than conventional dynamic capsules across a wide range of source distances.
• ShowLink Remote Control — IEEE 802.15.4 diversity wireless link allows real-time frequency coordination, output power changes, and muting from Wireless Workbench without interrupting audio.
• 184 MHz Tuning Range — Full-band frequency agility for deployment in any commercial RF environment, including RF-dense venues and convention centers.
• AES 256-Bit Encryption — Secure audio for corporate boardrooms, government spaces, and broadcast environments.
• High Density Mode — 125 kHz channel-to-channel spacing enables significantly more simultaneous wireless channels compared to Standard mode.
• Selectable RF Output: 2/10/40 mW — Adjustable transmit power optimizes the balance between range and channel density for any deployment scenario.
• SB920A Rechargeable Battery — Up to 9 hours at 10 mW with precision time-remaining metering and dockable charging.
• Interchangeable Capsule System — ADX2 body accepts all RPW-series wireless capsules for field reconfiguration.
• Cast Aluminum Housing — Commercial-grade durability suitable for touring inventory and permanent installation.

Typical Applications

• House of worship
• Auditorium
• Broadcast studio
• Conference room
• All-hands room
• Multi-purpose room
• Government space

Frequently Asked Questions

What makes the KSM8 capsule different from a standard dynamic?
The KSM8 uses a secondary floating rear diaphragm that acoustically cancels the proximity effect and narrows frequency response variation with distance. The result is a more consistent on- and off-axis response compared to conventional single-diaphragm dynamics, which is valuable in AV installations where speaker distance to the microphone varies.

Is the ADX2/K8N available in black finish?
The K8N variant uses the nickel (silver) capsule (RPW170) and is paired with a nickel transmitter body. For a black KSM8 capsule option on an ADX2 transmitter, the ADX2/K8B (RPW174) is the equivalent black-finish version.

What receivers work with the ADX2/K8N?
All Axient Digital receivers are compatible: AD4D, AD4Q, and ADX5D. The receiver’s frequency band must match the ADX2/K8N variant ordered (G57: 470–616 MHz is the single band offered on this SKU).

Does ShowLink require a separate access point?
ShowLink is built into the ADX2/K8N transmitter. It communicates with any ShowLink-compatible Axient Digital receiver or a dedicated ADSL access point. If using a non-ShowLink Axient Digital receiver (AD4D/AD4Q without ADSL), you can add an ADSL to enable ShowLink functionality.

What is the return and warranty policy?
Shure provides a 2-year limited warranty. Contact Creation Networks for support, warranty service, or pre-purchase configuration guidance.
