Shure AD2TA/K9B=-G57 Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule (G57: 470 to 616 MHz, Black) (TAA-Compliant)

Product Overview

The Shure AD2/KSM9 (TAA-Compliant) is a professional Axient Digital handheld wireless transmitter paired with the KSM9 premium condenser capsule, operating in the G57 frequency band (470–616 MHz) and designed for commercial AV deployments requiring condenser-quality audio capture. The KSM9 offers switchable supercardioid and cardioid polar patterns, giving AV system designers and audio engineers the flexibility to optimize gain-before-feedback and off-axis rejection for the specific acoustic characteristics of each venue. As a TAA-compliant wireless microphone, this transmitter meets U.S. federal procurement requirements and integrates into the Shure Axient Digital ecosystem with AES-256 encryption, High Density mode, and Wireless Workbench 6 management. Compatible with Shure Axient Digital G57-band receivers (AD4D, AD4Q, ADX4, ADX4D).

Product Description

The KSM9 condenser capsule uses a dual gold-layered, low-mass Mylar diaphragm design that captures vocal nuance and articulation with exceptional consistency across all frequencies. Switchable between supercardioid and cardioid polar patterns, the KSM9 allows on-site adjustment to balance gain-before-feedback versus off-axis rejection — a practical advantage in variable acoustic environments such as boardrooms, government hearing rooms, houses of worship, and multi-purpose commercial spaces. The AD2 transmitter body provides wide tuning across the G57 band (up to 184 MHz), selectable RF output at 2, 10, or 35 mW, and AES-256 encryption standard on every unit. The moisture-resistant aluminum housing withstands daily commercial-grade use, and the backlit LCD gives technicians real-time access to frequency, channel, RF level, and battery status. IR sync enables rapid pairing with Axient Digital receivers during commissioning, and Wireless Workbench 6 integration supports centralized spectrum coordination and remote monitoring across multi-transmitter installations. For a comparable Axient Digital transmitter with ShowLink capability, see the Shure ADX2/B58 at Creation Networks.

Key Features

• KSM9 Premium Condenser Capsule — Dual gold-layered, low-mass Mylar diaphragm design captures vocal detail with exceptional frequency consistency, delivering clear articulation for demanding live and installed AV applications.
• Switchable Polar Pattern (Supercardioid / Cardioid) — Field-adjustable polar pattern allows audio engineers to optimize gain-before-feedback or off-axis rejection based on the specific room geometry and acoustic environment.
• Axient Digital Compatible — Integrates natively with Shure Axient Digital G57-band receivers (AD4D, AD4Q, ADX4, ADX4D) for enterprise-scale wireless microphone deployments.
• AES-256 Encryption — Military-grade encryption is standard on all AD2 units, protecting audio transmission in government, legal, and sensitive commercial AV environments.
• Wide Tuning Range (up to 184 MHz) — Broad frequency agility across the G57 band enables RF coordination in dense wireless environments typical of large commercial AV installations.
• High Density Mode — Maximizes simultaneous channel count per RF band, critical for large conference rooms, all-hands rooms, and multi-room commercial installations.
• Selectable RF Output (2/10/35 mW) — Three output levels let AV designers balance range and channel density based on room geometry and channel plan requirements.
• Moisture-Resistant Aluminum Housing — Durable, lightweight construction engineered for daily commercial-grade use in demanding installed AV environments.
• Rechargeable Battery Support — Compatible with Shure SB900A lithium-ion rechargeable battery (sold separately) for up to 9 hours of operation with precision battery metering in hours and minutes.
• Wireless Workbench 6 Integration — Supports remote monitoring, frequency coordination, and networked charging management across multi-transmitter commercial installations.
• Interchangeable Capsule Design — KSM9 capsule can be swapped for other Shure capsules (KSM8, KSM9HS, SM58, Beta 87A, Beta 87C) to adapt the transmitter body across different applications.
• TAA Compliant — Qualifies for U.S. federal government procurement under the GSA Schedule and applicable federal contract vehicles.

Frequently Asked Questions

What is the difference between the KSM9 and KSM8 capsule on the AD2?
The KSM9 is a premium condenser capsule with a dual gold-layered Mylar diaphragm, offering switchable supercardioid and cardioid polar patterns and exceptional sensitivity for detailed vocal capture. The KSM8 is a Dualdyne dynamic capsule with a fixed cardioid pattern, offering robust handling noise rejection and natural sound with less sensitivity than the condenser KSM9. Condenser capsules like the KSM9 are typically preferred where audio quality and vocal detail are the primary consideration; dynamic capsules are often specified where durability and handling noise rejection are priorities.

How does the switchable polar pattern work on the KSM9?
The KSM9 capsule can be switched between supercardioid and cardioid polar patterns. Supercardioid offers tighter off-axis rejection and higher gain-before-feedback, useful in loud venues or when multiple speakers are in close proximity. Cardioid provides a wider acceptance angle, accommodating presenters who move or turn away from the microphone. The pattern switch is on the capsule itself and can be adjusted during system setup.

What receivers are compatible with this G57-band transmitter?
The AD2/KSM9 G57 is compatible with Shure Axient Digital G57-band receivers including the AD4D, AD4Q, ADX4, and ADX4D. Transmitter and receiver must be in the same frequency band for proper operation.

What does TAA compliant mean for this transmitter?
TAA (Trade Agreements Act) compliance means this unit qualifies for U.S. government procurement under the GSA Schedule and applicable federal contract vehicles. Government agencies and contractors on federal projects can include this transmitter in compliant wireless system bids.

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

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