Shure ADX2FDTA/K9B=-G57 Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule (G57: 470 to 616 MHz, Black) (TAA-Compliant)

Product Overview

The Shure ADX2FDTA/K9B=-G57 is a professional Axient Digital frequency diversity handheld wireless microphone transmitter equipped with the KSM9 condenser capsule in black, operating in the G57 frequency band (470–616 MHz). The KSM9 is Shure’s premium wireless condenser capsule, delivering studio-grade transparency and precision pickup suited to professional vocalists and broadcast applications where audio fidelity is the primary requirement. TAA-compliant for U.S. government and federally-funded education procurement, this transmitter provides both the signal resilience of frequency diversity technology and the acoustic performance of one of Shure’s most refined wireless capsules.

Product Description

The ADX2FDTA/K9B=-G57 is the specification choice for demanding commercial AV installations where premium condenser performance and maximum RF reliability are both required. The KSM9 capsule’s condenser design provides detailed, natural audio reproduction with high sensitivity and controlled polar response, making it a preferred option for lead vocalists, broadcast talent, and presenters in high-visibility productions. Frequency diversity simultaneously transmits on two independent RF carriers across the G57 band (470–616 MHz), protecting signal integrity in environments with significant RF interference. ShowLink® 2.4 GHz remote control gives operators real-time command over gain, mute, and RF parameters from front-of-house. SB920A rechargeable batteries deliver up to 6.5 hours runtime in FD mode and up to 9 hours in single-carrier mode. For the nickel finish version, see the Shure ADX2FDTA/K9N=-G57.

Frequently Asked Questions

How does the KSM9 differ from the KSM8 capsule?
The KSM9 is a condenser capsule that provides higher sensitivity, extended frequency response, and studio-grade transparency compared to the KSM8, which is a dual-diaphragm dynamic capsule. The KSM9 is preferred when maximum audio fidelity is the priority; the KSM8 is favored for high-SPL environments and durability.

What receivers are compatible with the ADX2FDTA/K9B=-G57?
This transmitter is compatible with Axient Digital receivers in the G57 band, such as the AD4D and AD4Q. Transmitter and receiver must operate in the same frequency band.

Is the ADX2FDTA/K9B=-G57 TAA-compliant?
Yes. The TA suffix confirms Trade Agreements Act compliance for U.S. federal, DoD, and GSA-funded procurement.

What is the difference between the K9B (black) and K9N (nickel) versions?
Both use the identical KSM9 condenser capsule with identical audio performance. The only difference is finish: black (K9B) versus nickel (K9N).
