Shure ADX2/K9B Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule (Black)

Product Overview

The Shure ADX2/K9B is a flagship Axient Digital handheld wireless transmitter paired with the KSM9 dual-pattern condenser capsule in black finish, targeting professional broadcast studios, performing arts centers, and large-scale commercial AV installations where the KSM9’s selectable cardioid/supercardioid polar pattern provides maximum operational flexibility. ShowLink remote control enables real-time parameter management from Wireless Workbench, and the 184 MHz tuning range supports deployment in any RF environment. AES 256-bit encryption and High Density mode complete the professional feature set of this Axient Digital wireless transmitter.

Product Description

The ADX2/K9B combines the ADX2 transmitter platform with the KSM9 condenser capsule, a professional cardioid/supercardioid dual-pattern capsule used in demanding live and broadcast vocal applications. The KSM9’s switchable polar pattern provides AV system designers with flexibility—cardioid for wide pickup in boardroom and conference deployments, or supercardioid for tight rejection in feedback-prone auditorium and stage applications. The ADX2 body adds ShowLink diversity control, enabling engineers to change frequency, adjust output power, or mute channels remotely from Wireless Workbench without physically accessing the transmitter. At 40 mW maximum output power, the ADX2/K9B supports extended-range deployments. The SB920A rechargeable battery (included) delivers up to 9 hours at 10 mW with full precision battery metering on the receiver display.

Frequently Asked Questions

How does the KSM9 dual-pattern capsule work?
The KSM9 capsule has a physical switch that changes the polar pattern between cardioid and supercardioid. Cardioid provides a wider pickup pattern suited for presentations and spoken-word applications; supercardioid provides tighter off-axis rejection for stage performance environments with monitor wedges or other nearby sound sources.

What is the ADX2/K9B versus the ADX2/K9N?
The ADX2/K9B uses the black-finish KSM9 capsule (RPW184), while the ADX2/K9N uses the nickel-finish KSM9 capsule (RPW188). The capsule acoustic performance is identical; the difference is purely cosmetic.

Does the ADX2/K9B require a ShowLink access point separately?
ShowLink is built into the ADX2/K9B transmitter. It communicates with a ShowLink-compatible Axient Digital receiver or a dedicated ADSL access point connected to Wireless Workbench. If your Axient Digital receivers are ShowLink-capable (e.g., ADX5D), no separate access point is required.

What is the warranty?
