Shure ADX2FD/K8B Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (Black)

Product Overview

The Shure ADX2FD/K8B is a frequency-diverse digital handheld wireless microphone transmitter featuring the KSM8 dual-diaphragm cardioid dynamic capsule in a black finish, designed for live productions, broadcast applications, and commercial AV deployments where a dynamic capsule is preferred for high-SPL environments. The KSM8’s dual-diaphragm design provides a flat, natural frequency response characteristic of studio condenser microphones while maintaining the durability and feedback rejection of a dynamic capsule. Frequency diversity transmits on two independent RF paths simultaneously, and ShowLink remote control enables engineers to manage settings from Wireless Workbench 6 or ShurePlus Channels during live events without interrupting audio.

Product Description

The ADX2FD/K8B pairs the Axient Digital frequency-diverse platform with the Shure KSM8 capsule—a dual-diaphragm cardioid dynamic microphone that delivers a condenser-like flat response while handling high sound pressure levels common in live vocal and broadcast applications. This combination makes it effective for high-energy live productions, house of worship applications, and commercial venues where feedback control and sound pressure performance are priorities. Frequency diversity ensures continuous audio even in congested RF environments, while HD mode enables scaling up channel counts in large-venue deployments. Available in black finish in G57 (470–616 MHz) and X55 (941–960 MHz) bands. Works with the Shure AD4DNP Two-Channel Receiver or Shure AD4QUS Four-Channel Receiver.

Frequently Asked Questions

What makes the KSM8 capsule distinctive for live commercial applications?
The KSM8 uses a dual-diaphragm design that provides a flat, natural frequency response similar to condenser microphones, while retaining the high SPL handling and feedback resistance of a dynamic capsule. This makes it particularly suited for high-energy live productions, large-format auditoriums, and house of worship applications where feedback control is critical.

Is the ADX2FD/K8B compatible with existing Axient Digital receivers?
Yes. It is compatible with all Axient Digital AD4D and AD4Q receivers in Standard and High Density modes.

What frequency bands are available for the ADX2FD/K8B?
The ADX2FD/K8B is available in G57 (470–616 MHz) and X55 (941–960 MHz) frequency bands. When purchasing components for an Axient Digital system, ensure all transmitters and receivers are ordered in matching frequency bands.
