Shure ADX2FD/K9N Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule (Nickel)

Product Overview

The Shure ADX2FD/K9N is a frequency-diverse digital handheld wireless microphone transmitter featuring the KSM9 switchable cardioid/supercardioid condenser capsule in a nickel finish, designed for broadcast production, live commercial events, and installed AV applications requiring studio-quality wireless audio with maximum RF performance. The nickel finish makes it well-suited for broadcast facilities and theatrical productions where a traditional microphone appearance is preferred. Frequency-diverse transmission provides automatic dual-frequency interference avoidance, and ShowLink remote control enables engineers to manage the transmitter remotely during live productions via Wireless Workbench 6 or ShurePlus Channels.

Product Description

The ADX2FD/K9N pairs the KSM9—one of Shure’s flagship condenser capsules with switchable cardioid and supercardioid patterns—with the Axient Digital frequency-diverse RF platform. Switchable polar patterns allow adapting pickup coverage to different stage or room configurations without changing hardware, providing flexibility for broadcast environments, auditoriums, and corporate all-hands venues. The frequency-diverse architecture transmits simultaneously on two independent RF paths, providing automatic interference avoidance critical for mission-critical commercial productions and broadcast facilities. HD mode maximizes simultaneous channel capacity in spectrum-constrained deployments. Available in G57 band (470–616 MHz), nickel finish. Integrates with the Shure AD4DNP Two-Channel Receiver or Shure AD4QUS Four-Channel Receiver.

Frequently Asked Questions

What is the difference between the ADX2FD/K9N and ADX2FD/K9B?
Both transmitters use the same KSM9 capsule with identical RF and audio performance. The K9N is nickel/silver finish and the K9B is black. Selection is typically based on visual preference or the conventions of the broadcast facility or production.

Is the ADX2FD/K9N compatible with existing Axient Digital receivers?
Yes. It works with all Axient Digital AD4D and AD4Q receivers in Standard and High Density operating modes.

Can the KSM9 polar pattern be switched in the field?
Yes. The KSM9 capsule supports in-field polar pattern switching between cardioid and supercardioid, allowing AV engineers to adjust the microphone’s pickup characteristics for different room configurations or production requirements without hardware changes.
