Shure AD2TA/K8N=-G57 Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (G57: 470 to 616 MHz, Nickel) (TAA-Compliant)

Product Overview

The Shure AD2/KSM8 (TAA-Compliant) in nickel finish is a professional Axient Digital handheld wireless transmitter paired with the KSM8 Dualdyne dynamic capsule, operating in the G57 frequency band (470–616 MHz). The nickel finish is a common specification for productions and installations where the transmitter appearance on stage or at a podium is a consideration, while delivering identical RF performance and audio quality to the black variant. As a TAA-compliant wireless microphone, it meets U.S. federal procurement requirements and integrates into the Axient Digital ecosystem with AES-256 encryption, High Density mode, and Wireless Workbench 6 management. Compatible with Shure Axient Digital receivers (AD4D, AD4Q, ADX4, ADX4D) in the G57 band.

Product Description

The AD2 transmitter body pairs with Shure's KSM8 Dualdyne dynamic capsule — a patented two-diaphragm design with one active and one passive diaphragm in an inverted airflow system. This construction delivers exceptional control of proximity effect, allowing presenters and performers to maintain natural vocal tone at greater working distances with reduced feedback risk. The nickel-finished aluminum housing is moisture-resistant and lightweight, suited for daily commercial deployment in boardrooms, government hearing rooms, training facilities, and broadcast studios. Selectable RF output at 2, 10, or 35 mW lets integrators optimize for either extended range (up to 100 m line of sight) or High Density multi-channel configurations. The backlit LCD provides instant access to frequency, channel, RF level, and battery status, while lockout functions prevent unauthorized changes during live events. The TAA-compliant designation qualifies this transmitter for U.S. government GSA Schedule purchasing.

Technical Specifications

Frequently Asked Questions

Why would I specify the nickel finish over black?
Nickel finish is common in productions and installations where the microphone is visible to the audience or on camera, such as podium presentations, broadcast sets, and houses of worship. Both black and nickel variants offer identical RF performance and audio quality; finish selection is primarily aesthetic.

What receivers are compatible with this transmitter?
The AD2/KSM8 G57-band requires Shure Axient Digital receivers in the G57 band, including the AD4D, AD4Q, ADX4, and ADX4D. Both transmitter and receiver must operate in the same frequency band for proper system operation.

What does TAA compliant mean for this transmitter?
TAA compliance qualifies this unit for U.S. federal procurement under GSA Schedule and applicable contract vehicles. Government agencies and contractors on federal projects can purchase this transmitter through compliant procurement channels.

Can the capsule be swapped for a different Shure capsule?
Yes. The AD2 uses an interchangeable capsule design. The KSM8 Dualdyne can be replaced with other Shure capsules including the KSM9, KSM9HS, SM58, Beta 87A, and Beta 87C, making the transmitter body adaptable across applications.

What are the battery and charging options?
The AD2 accepts 2x AA alkaline batteries for up to 8 hours of operation. The Shure SB900A rechargeable battery (sold separately) provides up to 9 hours. Shure SBC220 and SBC840 networked chargers support remote battery monitoring via Wireless Workbench 6.

What warranty coverage applies?
Shure provides a limited 2-year manufacturer warranty. Contact Creation Networks for commercial installation support and warranty registration assistance.
