Shure ADX2/K8B Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (Black)

Product Overview

The Shure ADX2/K8B is a ShowLink-enabled digital handheld wireless microphone transmitter for the Axient Digital Wireless System, paired with the KSM8 dual-diaphragm cardioid dynamic capsule in a black finish. Built for commercial AV integrators, broadcast engineers, and touring production professionals who require reliable wireless performance in RF-dense environments, the ADX2/K8B delivers wide 184 MHz tuning bandwidth and real-time remote parameter control via ShowLink without interrupting a live event. It operates with all Shure Axient Digital receivers including the Shure AD4Q-DC Four-Channel Wireless Receiver and requires matching frequency bands between transmitter and receiver.

Product Description

Designed for demanding commercial AV deployments where consistent wireless performance is non-negotiable, the Shure ADX2/K8B combines the Axient Digital transmitter platform with the KSM8 capsule—a dual-diaphragm cardioid dynamic microphone designed to handle high SPLs and deliver natural, detailed vocal reproduction suited to live sound reinforcement, house of worship, and broadcast environments. The ADX2/K8B features selectable RF output power (2/10/40 mW), allowing AV system designers to balance transmitter power against battery life based on venue size and RF environment. ShowLink technology provides over-the-air remote control of transmitter gain, mute, RF power, and other parameters directly from the mix position using a compatible Axient Digital receiver and Wireless Workbench 6 software—without requiring physical access to the transmitter. The SB920 rechargeable lithium-ion battery provides up to 9 hours of runtime at 10 mW, and the transmitter accepts standard AA batteries as a backup power option.

Key Features

• KSM8 Dual-Diaphragm Cardioid Dynamic Capsule — Delivers natural vocal reproduction with controlled rear rejection, suited to high-SPL live sound environments, podiums, and stage applications where ambient noise rejection is important.
• ShowLink Remote Control — Enables real-time over-the-air parameter adjustments (gain, mute, RF power) from the booth or control room without physical access to the transmitter on talent.
• 184 MHz Ultra-Wide Tuning Bandwidth — Provides broad frequency agility within the purchased band, allowing technicians to avoid interference in congested commercial RF environments and spectrum-limited venues.
• Selectable RF Output Power — Three power settings (2/10/40 mW) allow AV integrators to optimize transmitter range versus battery life for each specific installation or event scenario.
• SB920 Rechargeable Li-Ion Battery — Provides up to 9 hours of runtime at 10 mW, with networked battery monitoring via Wireless Workbench 6 for proactive charge management across large systems.
• Axient Digital System Integration — Fully compatible with all Shure AD4 and ADX4 series Axient Digital receivers, supporting High Density mode, frequency diversity, and Quadversity configurations.
• Sleek Metal Construction — Durable metal body in a professional black finish provides the build quality and hand feel expected in commercial AV, broadcast, and touring applications.
• Interference Detection and Avoidance — Axient Digital’s interference detection and automatic frequency avoidance work with the ADX2/K8B to maintain signal integrity without operator intervention during live events.

Frequently Asked Questions

Which receivers are compatible with the ADX2/K8B?
The ADX2/K8B is compatible with all Shure Axient Digital receivers, including the AD4D (two-channel) and AD4Q/AD4Q-DC (four-channel) receivers. Ensure the transmitter and receiver are purchased in matching frequency bands (G57, K54, or X55).

What is the KSM8 capsule and why use it over other options?
The KSM8 is a dual-diaphragm cardioid dynamic microphone capsule designed for natural vocal reproduction with high SPL handling. It is particularly suited to live sound reinforcement, house of worship, and broadcast environments where a natural, dynamic sound is preferred over a condenser character.

Does the ADX2/K8B support rechargeable batteries?
Yes. The ADX2/K8B uses the Shure SB920 rechargeable lithium-ion battery, providing up to 9 hours of runtime at 10 mW. Battery charge status is visible in real time via Wireless Workbench 6 software when used with a compatible Axient Digital receiver.

Can transmitter parameters be adjusted remotely during a live event?
Yes. ShowLink technology allows real-time over-the-air remote control of gain, mute, RF output power, and other parameters from the mix position or system control station, without physically accessing the transmitter.

What warranty does the ADX2/K8B include?
Shure provides a two-year limited warranty. Contact Creation Networks for pre-sale system design support, frequency coordination assistance, and post-purchase technical service.
