Shure ADX2TA/K9HSB=-G57 Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule (G57: 470 to 616 MHz, Black) (TAA-Compliant)

Product Overview

The Shure ADX2TA/K9HSB=-G57 is a TAA-compliant Axient Digital handheld wireless transmitter equipped with the KSM9HS high-sensitivity switchable-pattern condenser capsule in a black finish, operating in the G57 band (470–616 MHz). The KSM9HS is optimized for quieter sound sources and applications where maximum gain-before-feedback is required, making this transmitter well-suited for softer vocal performers, government panel discussions, and broadcast environments where presenter mic technique is variable. It integrates with any G57-band Axient Digital receiver for a complete commercial wireless solution.

Product Description

The ADX2TA/K9HSB=-G57 builds on the standard ADX2 platform with the addition of the KSM9HS high-sensitivity condenser capsule, which provides greater output for lower-level audio sources without requiring additional downstream gain. This is particularly useful in panel-style conference room deployments, government hearing rooms, and broadcast studios where presenters may not consistently project toward the microphone. The switchable cardioid and supercardioid patterns give the AV system designer additional control over pickup focus and rear rejection based on the room layout and speaker monitoring configuration.

The 184 MHz tuning range within the G57 band, ShowLink remote management, and AES 256-bit encryption provide the enterprise RF infrastructure expected of the Axient Digital platform. High Density mode reduces channel spacing to 125 kHz for large multi-channel deployments. For a nickel-finish variant of this model, see the Shure ADX2/K9HSN. For the standard-sensitivity KSM9 variant, see the Shure ADX2TA/K9B=-G57.

Key Features

• TAA Compliance — Manufactured per Trade Agreements Act requirements, eligible for US federal government and GSA schedule procurement without waivers.
• KSM9HS High-Sensitivity Condenser Capsule — Elevated sensitivity captures quieter sound sources with greater clarity, reducing the gain required from downstream amplification and minimizing noise floor contribution.
• Switchable Cardioid/Supercardioid Pattern — Adapts pickup polar pattern to match room acoustics, speaker positioning, and feedback margin requirements without hardware changes.
• G57 Frequency Band (470–616 MHz) — 184 MHz tuning range provides maximum frequency coordination flexibility in congested UHF environments.
• ShowLink Remote Control — IEEE 802.15.4 wireless management enables real-time parameter adjustment from the operator position without interrupting live audio.
• AES 256-Bit Encryption — Secures audio transmission for government, legal, and enterprise security applications.
• High Density Mode — 125 kHz channel spacing increases simultaneous channel capacity for large multi-system commercial deployments.
• Selectable RF Power (2/10/40 mW) — Transmit power selection balances operating range with battery runtime for each installation.
• SB920 Rechargeable Li-Ion Battery — Up to 9 hours runtime at 10 mW with precision fuel-gauge metering and docked charging support.
• Cast Aluminum Construction — Rugged, professional-grade housing for commercial AV environments.

Frequently Asked Questions

What is the difference between the KSM9HS and the standard KSM9 capsule?
The KSM9HS is a high-sensitivity variant of the KSM9 condenser capsule. It is optimized to capture quieter sound sources with greater clarity, reducing the gain needed from the downstream audio chain. This makes it a better choice for softer-spoken presenters, panel discussions, and environments where the presenter may not consistently hold the microphone at a standard distance.

What receiver is required for the ADX2TA/K9HSB=-G57?
This transmitter requires an Axient Digital receiver in the G57 band, such as the ADX4 or ADX4D. Frequency band must match between transmitter and receiver.

Is this eligible for US government procurement?
Yes. The "TA" designation confirms TAA compliance. This unit is eligible for US federal contracts and GSA schedule purchases.

Can the KSM9HS capsule be swapped for another cartridge?
Yes. The ADX2 body uses an interchangeable cartridge system compatible with all standard Shure wireless capsule accessories. Swapping capsules requires only unscrewing the transmitter handle.

What is the warranty on this product?
Shure provides a two-year limited warranty on the ADX2TA transmitter body and a one-year limited warranty on the SB920 battery.
