Shure ADX2FDTA/K8N=-G57 Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (G57: 470 to 616 MHz, Nickel) (TAA-Compliant)

Product Overview

The Shure ADX2FDTA/K8N=-G57 is a professional Axient Digital frequency diversity handheld wireless microphone transmitter equipped with the KSM8 dual-diaphragm cardioid dynamic capsule in nickel finish, operating in the G57 frequency band (470–616 MHz). TAA-compliant for U.S. government and federally-funded education procurement, this transmitter delivers the same audio and RF performance as the black K8B variant with a nickel finish preferred in certain stage and installation aesthetics. Frequency diversity transmits on two simultaneous, independent RF carriers to ensure uninterrupted signal delivery in complex wireless environments. Commercial AV integrators and system designers building Axient Digital wireless infrastructure will benefit from the K8N’s broad spectrum flexibility, rechargeable battery system, and deep integration with Shure’s management ecosystem.

Product Description

The ADX2FDTA/K8N=-G57 pairs the Axient Digital frequency diversity platform with the KSM8 dual-diaphragm cardioid dynamic capsule in a nickel finish. The KSM8 is engineered for consistent cardioid polar response and natural, warm sound capture, making it a strong choice for lead vocals, conference presenters, and broadcast hosts in professional AV environments. The nickel finish provides an alternative aesthetic option while maintaining identical performance to the K8B black variant. ShowLink® 2.4 GHz remote control gives AV operators real-time command over gain, mute, and RF parameters from front-of-house without interrupting a live program. With up to 184 MHz of tuning bandwidth across the G57 band, the transmitter accommodates complex multi-channel wireless system deployments. For the matching black finish variant, see the Shure ADX2FDTA/K8B=-G57.

Frequently Asked Questions

Is the nickel (K8N) version different from the black (K8B) in audio performance?
No. The K8N and K8B use identical KSM8 dual-diaphragm cardioid dynamic capsules and deliver identical audio performance. The only difference is the exterior finish: nickel versus black.

What does TAA-compliant mean for federal procurement?
TAA compliance (denoted by the TA suffix) means the product meets Trade Agreements Act manufacturing origin requirements, qualifying it for purchase under U.S. federal GSA schedules, DoD contracts, and other government procurement vehicles.

What Axient Digital receivers are compatible?
This transmitter is compatible with Axient Digital G57-band receivers, including the AD4D (dual-channel) and AD4Q (quad-channel). Band must match between transmitter and receiver.

What is the capsule replacement option for the KSM8 in nickel finish?
The RPW170 wireless capsule adapter is designed for nickel-finish Shure transmitters and accepts KSM8-compatible elements. Consult the Shure capsule compatibility guide before ordering replacement or alternate capsules.
