Shure AD2TA/K8B=-G57 Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (G57: 470 to 616 MHz, Black) (TAA-Compliant)

Product Overview

The Shure AD2/KSM8 (TAA-Compliant) is a professional Axient Digital handheld wireless transmitter paired with the KSM8 Dualdyne dynamic capsule, engineered for commercial AV integration in the G57 frequency band (470–616 MHz). Designed for AV system designers, integrators, and IT/facilities managers specifying government, enterprise, and higher-education installations, this TAA-compliant wireless microphone meets U.S. federal procurement requirements without compromising RF performance or audio quality. With AES-256 encryption, High Density mode, and compatibility with the Axient Digital ecosystem, the AD2/KSM8 is a reliable centerpiece for multi-zone wireless microphone deployments managed via Wireless Workbench 6. For procurement staff and integrators building compliant AV systems, this transmitter ships as a G57-band unit compatible with Shure AD4D, AD4Q, ADX4, and ADX4D receivers.

Product Description

The AD2 transmitter body pairs with Shure's KSM8 Dualdyne dynamic capsule — a patented two-diaphragm design featuring one active and one passive diaphragm in an inverted airflow system. This construction delivers exceptional control of proximity effect, allowing presenters to work at greater distances without on-axis coloration, and significantly reduces the EQ compensation required during system commissioning. The aluminum housing is moisture-resistant and lightweight, suited for daily commercial-grade use in boardrooms, government hearing rooms, auditoriums, and broadcast studios. Selectable RF output at 2, 10, or 35 mW lets AV designers optimize for either extended range (up to 100 m line of sight) or High Density multi-channel configurations. The backlit LCD gives technicians instant visibility into frequency, channel, RF level, and battery status; frequency and power lockout functions prevent unauthorized changes during live events. IR sync enables rapid pairing with Axient Digital receivers during commissioning. For installations requiring federal procurement compliance, this unit carries TAA-compliant designation confirming it qualifies for U.S. government GSA Schedule purchasing. For a ShowLink-enabled upgrade path, see the Shure ADX2/B58 Axient Digital Transmitter also available at Creation Networks.

Key Features

• KSM8 Dualdyne Dynamic Capsule — Patented two-diaphragm design with inverted airflow technology delivers natural vocal reproduction with exceptional control of proximity effect and improved feedback rejection for live and installed AV environments.
• Axient Digital Compatible — Integrates natively with Shure Axient Digital receivers (AD4D, AD4Q, ADX4, ADX4D) for enterprise-scale wireless microphone deployments requiring centralized management.
• AES-256 Encryption — Military-grade encryption protects audio transmission from interception, a critical requirement for government meeting spaces, legal proceedings, and sensitive commercial environments.
• Wide Tuning Range (up to 184 MHz) — Broad frequency agility across the G57 band (470–616 MHz) enables RF coordination in dense wireless environments typical of large commercial facilities.
• High Density Mode — Enables maximum simultaneous channel count per RF band, essential for large conference rooms, all-hands rooms, and multi-room commercial installations.
• Selectable RF Output (2/10/35 mW) — Three RF output levels allow AV designers to balance range and channel density according to room geometry and channel plan requirements.
• Moisture-Resistant Aluminum Housing — Lightweight, durable construction withstands daily commercial use in boardrooms, government spaces, auditoriums, and training facilities.
• Rechargeable Battery Support — Compatible with the Shure SB900A lithium-ion rechargeable battery (sold separately) for up to 9 hours of operation with precision battery metering displayed in hours and minutes.
• Wireless Workbench 6 Integration — Supports remote monitoring, frequency coordination, and networked charging management across multi-transmitter installations via Shure's Wireless Workbench 6 software.
• Interchangeable Capsule Design — KSM8 capsule can be swapped for other Shure capsules (KSM9, KSM9HS, SM58, Beta 87A, Beta 87C, and others), allowing the transmitter body to serve multiple applications across an installation.
• TAA Compliant — Meets Trade Agreements Act requirements for U.S. federal government procurement, qualifying this transmitter for GSA Schedule purchasing and federal contract vehicles.

Frequently Asked Questions

What receivers are compatible with the Shure AD2/KSM8?
The AD2/KSM8 is compatible with Shure Axient Digital receivers: AD4D (dual-channel), AD4Q (quad-channel), ADX4, and ADX4D. It is not compatible with ULX-D, SLX-D, or other Shure system families. Confirm your receiver is part of the Axient Digital series before ordering.

What does TAA compliant mean for this transmitter?
TAA (Trade Agreements Act) compliance means this unit qualifies for U.S. government purchasing under the GSA Schedule and federal contract vehicles that restrict purchases to goods manufactured or substantially transformed in designated countries. Procurement managers supporting government facilities can include this transmitter in compliant wireless microphone system bids.

Can the KSM8 capsule be swapped for a different Shure capsule?
Yes. The AD2 transmitter uses an interchangeable capsule design. You can replace the KSM8 with other Shure capsules including the KSM9, KSM9HS, SM58, Beta 87A, Beta 87C, and VP68, making the transmitter body adaptable across different deployment scenarios.

How does High Density mode affect channel count in an Axient Digital system?
High Density mode allows more simultaneous wireless channels to coexist within the available RF spectrum compared to Standard mode. This is essential for large conference rooms, all-hands spaces, and event venues where many wireless microphone channels must operate in a limited frequency allocation.

Is the G57 band appropriate for my installation location?
The G57 band (470–616 MHz) covers UHF spectrum typically available in North America for licensed wireless microphone use. Before purchasing, use Shure's Frequency Finder tool at shure.com or consult a frequency coordinator to confirm G57 is available and legally operable in your specific geographic area.

What are the charging and power management options?
The AD2 accepts 2x AA alkaline batteries (included) for up to 8 hours of operation. For commercial deployments, the Shure SB900A rechargeable battery (sold separately) provides up to 9 hours with precision metering. The SBC220 dual-bay and SBC840 eight-bay networked chargers support remote power monitoring via Wireless Workbench 6 for centralized battery management.

What warranty does Shure provide on the AD2?
Shure provides a limited 2-year manufacturer warranty covering defects in materials and workmanship. Contact Creation Networks for assistance with warranty registration and commercial service support options.
