Shure AD2TA/K9HSB=-G57 Digital Handheld Wireless Microphone Transmitter with KSM9HS Capsule (G57: 470 to 616 MHz, Black) (TAA-Compliant)

Product Overview

The Shure AD2/KSM9HS (TAA-Compliant) is a professional Axient Digital handheld wireless transmitter paired with the KSM9HS premium condenser capsule, designed for commercial AV installations where maximum gain-before-feedback and precise polar pattern control are critical requirements. Operating in the G57 frequency band (470–616 MHz), the KSM9HS features switchable hypercardioid and subcardioid polar patterns — a specialized combination that gives audio engineers and AV system designers fine control over off-axis rejection and pickup angle in acoustically demanding environments. The KSM9HS captures extraordinary vocal detail with a dual Mylar diaphragm, suited for high-profile presentations, broadcast studios, auditoriums, and commercial meeting spaces where condenser-quality audio and tight pattern control are specified together. TAA compliant for U.S. federal procurement. Compatible with Shure Axient Digital G57-band receivers (AD4D, AD4Q, ADX4, ADX4D).

Product Description

The KSM9HS condenser capsule uses a dual Mylar diaphragm design with switchable hypercardioid and subcardioid polar patterns — two specialized pattern positions that distinguish the KSM9HS from the standard KSM9 (supercardioid/cardioid). Hypercardioid provides maximum gain-before-feedback and tight off-axis rejection, making it the preferred choice for loud stages, houses of worship, and auditoriums where monitor speakers or adjacent sound sources are common. Subcardioid offers a wider, more forward-facing acceptance angle that captures presenters who move or turn slightly away from the microphone, useful in conference rooms, training facilities, and government hearing rooms. The AD2 transmitter platform delivers wide tuning across the G57 band (up to 184 MHz), selectable RF output at 2, 10, or 35 mW, and AES-256 encryption on every unit, housed in moisture-resistant aluminum construction suitable for daily commercial-grade deployment. IR sync enables fast pairing with G57-band Axient Digital receivers, and Wireless Workbench 6 integration supports centralized frequency coordination and remote monitoring. For a ShowLink-enabled Axient Digital upgrade, see the Shure ADX2/B58 at Creation Networks.

Key Features

• KSM9HS Premium Condenser Capsule — Dual Mylar diaphragm design captures extraordinary vocal detail with exceptional frequency consistency, engineered for demanding live and installed commercial AV environments.
• Switchable Polar Pattern (Hypercardioid / Subcardioid) — Field-adjustable between hypercardioid for maximum gain-before-feedback and tight rejection, or subcardioid for a wider forward pickup angle — two specialized positions not available on standard KSM9.
• Axient Digital Compatible — Integrates natively with Shure Axient Digital G57-band receivers for enterprise-scale wireless microphone management via Wireless Workbench 6.
• AES-256 Encryption — Military-grade encryption standard on all AD2 units, protecting audio transmission in government, legal, and sensitive commercial AV installations.
• Wide Tuning Range (up to 184 MHz) — Broad frequency agility across the G57 band enables effective RF coordination in dense multi-channel wireless environments.
• High Density Mode — Maximizes simultaneous channel count per RF band, critical for large conference rooms, all-hands spaces, and multi-room commercial installations.
• Selectable RF Output (2/10/35 mW) — Three RF output levels allow AV system designers to optimize for range or channel density based on installation requirements.
• Moisture-Resistant Aluminum Housing — Lightweight, durable construction engineered for daily commercial-grade deployment across demanding AV environments.
• Rechargeable Battery Support — Compatible with Shure SB900A lithium-ion battery (sold separately) for up to 9 hours of operation with precision hour/minute metering.
• Interchangeable Capsule Design — KSM9HS capsule can be replaced with other Shure capsules (KSM8, KSM9, SM58, Beta 87A) without tools for cross-application versatility.
• 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 KSM9HS and the KSM9 capsule?
The KSM9HS offers switchable hypercardioid and subcardioid polar patterns, while the standard KSM9 switches between supercardioid and cardioid. Hypercardioid provides tighter off-axis rejection and higher gain-before-feedback than supercardioid — useful in louder environments. Subcardioid offers a wider forward pickup angle than cardioid, accommodating presenters who move or turn. The KSM9HS is the specialized choice when pattern extremes are required.

What is subcardioid, and when would I specify it?
Subcardioid is a pickup pattern wider than cardioid with minimal rear rejection — it captures sound in a broad forward-facing arc. It is useful in installations where a presenter moves significantly relative to the microphone, or where a single transmitter needs to capture multiple speakers in close proximity. For maximum rejection of off-axis sources, hypercardioid mode is the alternative setting on the KSM9HS.

What receivers are compatible with this G57-band transmitter?
The AD2/KSM9HS G57 is compatible with Shure Axient Digital G57-band receivers including the AD4D, AD4Q, ADX4, and ADX4D. Transmitter and receiver must operate in the same frequency band.

What does TAA compliant mean for this transmitter?
TAA compliance means this unit qualifies for U.S. federal procurement under the GSA Schedule and applicable federal contract vehicles. Government agencies and contractors can include this transmitter in compliant wireless system specifications.

What are the battery and charging options?
The AD2 accepts 2x AA alkaline batteries for up to 8 hours or the Shure SB900A rechargeable (sold separately) for up to 9 hours. 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.
