Shure ADX2TA/K8N=-G57 Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (G57: 470 to 616 MHz, Nickel) (TAA-Compliant)

Product Overview

The Shure ADX2TA/K8N is a TAA-compliant Axient Digital handheld wireless transmitter equipped with the KSM8 dual-diaphragm cardioid dynamic capsule in a nickel finish. Built for US federal government procurement and professional AV installation, it operates in the G57 frequency band (470–616 MHz) and integrates directly with any Axient Digital wireless system. This transmitter is the right choice for conference rooms, government spaces, and large-scale AV deployments where TAA compliance is a procurement requirement.

Product Description

The ADX2TA/K8N delivers 184 MHz of tuning range within the G57 band, giving AV integrators maximum flexibility for frequency coordination in congested UHF environments. The KSM8 dual-diaphragm dynamic capsule produces natural vocal reproduction with reduced proximity effect, making it reliable for a wide range of presenter vocal dynamics without requiring gain adjustments. ShowLink remote control enables real-time parameter changes from the mix position — gain, mute, and frequency adjustments — without interrupting a live program. AES 256-bit encryption supports secure RF transmission in government facilities, legal settings, and sensitive corporate environments. For a non-TAA comparable, see the Shure ADX2/K8N; for a complementary transmitter option with Beta 58A capsule, see the Shure ADX2/B58.

High Density mode reduces channel-to-channel spacing to 125 kHz, significantly increasing the maximum number of simultaneous channels — critical for all-hands rooms, large conference centers, and government facilities running multiple wireless systems concurrently. The cast aluminum body and SB920 rechargeable lithium-ion battery round out a transmitter built for professional daily use.

Key Features

• TAA Compliance — Meets Trade Agreements Act requirements, making this transmitter eligible for US federal government and GSA schedule procurement without exception.
• KSM8 Dual-Diaphragm Dynamic Capsule — Cardioid polar pattern with reduced proximity effect delivers consistent, natural vocal reproduction across a wide range of presenter levels and distances.
• G57 Frequency Band (470–616 MHz) — 184 MHz of tuning range within the UHF G57 band provides maximum coordination flexibility in high-RF-density commercial environments.
• ShowLink Remote Control — IEEE 802.15.4 wireless link (2.40–2.4835 GHz) enables real-time transmitter management from Wireless Workbench without physical access to the microphone.
• AES 256-Bit Encryption — Supports secure RF audio transmission for government, legal, and enterprise security applications.
• High Density Mode — 125 kHz channel spacing (vs. 350 kHz in Standard mode) dramatically increases simultaneous channel capacity for large deployments.
• Selectable RF Power (2/10/40 mW) — Adjustable transmit levels balance coverage range with battery runtime for the specific venue footprint.
• SB920 Rechargeable Li-Ion Battery — Up to 9 hours runtime at 10 mW with precision fuel-gauge metering, zero memory effect, and docked charging via compatible Shure chargers.
• Cast Aluminum Construction — Rugged, lightweight housing withstands frequent use in live events, conference rooms, and government facilities.
• Interchangeable Cartridge System — Compatible with the full range of Shure wireless capsules for future reconfiguration without replacing the transmitter body.

Frequently Asked Questions

What receiver is required for the ADX2TA/K8N=-G57?
This transmitter requires an Axient Digital receiver operating in the G57 band, such as the ADX4 or ADX4D. Frequency band of the transmitter and receiver must match for proper operation.

Is this transmitter eligible for US government procurement through GSA schedules?
Yes. The "TA" in the SKU denotes TAA compliance. This transmitter is manufactured in accordance with the Trade Agreements Act and is eligible for procurement under US federal contracts and GSA schedules.

Can I swap the KSM8 capsule for a different cartridge?
Yes. The ADX2 body accepts interchangeable Shure wireless cartridges including the RPW112 (SM58), RPW118 (Beta 58A), RPW184 (KSM9 Black), and RPW174 (KSM8 Black). Capsule changes require only unscrewing the handle — no tools or firmware updates needed.

How does ShowLink improve live AV operations?
ShowLink provides a 2.4 GHz IEEE 802.15.4 wireless link between the transmitter and a connected access point or receiver. Operators can adjust transmitter parameters in Wireless Workbench — gain offset, mute, frequency — in real time without walking to the stage or interrupting a live event.

What is the warranty on this product?
Shure provides a two-year limited warranty on the ADX2TA transmitter body. The SB920 battery is covered by a one-year limited warranty. Contact an authorized Shure dealer or Shure directly for warranty service.
