Shure AD2TA/K8B=-X55 Digital Handheld Wireless Microphone Transmitter with KSM8 Capsule (X55: 941 to 960 MHz, Black) (TAA-Compliant)

Product Overview

The Shure AD2/KSM8 (TAA-Compliant) in the X55 frequency band (941–960 MHz) is a professional Axient Digital handheld wireless transmitter paired with the KSM8 Dualdyne dynamic capsule, built for commercial AV deployments where the upper UHF spectrum offers cleaner operating conditions. The X55 band is particularly valuable for installations in markets with heavy broadcast TV interference in the lower UHF bands, giving AV system designers an alternative frequency allocation for multi-zone wireless microphone systems. With AES-256 encryption, High Density mode, and full Wireless Workbench 6 integration, this TAA-compliant wireless microphone transmitter meets both federal procurement and professional AV performance requirements. Compatible with Shure Axient Digital receivers (AD4D, AD4Q, ADX4, ADX4D) matched to the X55 band.

Product Description

The AD2 transmitter body pairs with Shure's KSM8 Dualdyne dynamic capsule — a patented two-diaphragm design featuring one active and one passive diaphragm in an inverted airflow system. This construction delivers exceptional control of proximity effect, allowing presenters to work at greater distances without on-axis coloration, and reduces the EQ compensation required during system commissioning. The aluminum housing is moisture-resistant and lightweight, suited for daily commercial-grade use in boardrooms, government facilities, auditoriums, and broadcast studios. Selectable RF output at 2, 10, or 35 mW lets integrators optimize for extended range (up to 100 m line of sight) or High Density multi-channel configurations. The backlit LCD gives technicians at-a-glance access to frequency, channel, RF level, and battery status, while frequency and power lockout functions prevent unauthorized adjustments during live events. For government installations requiring federal procurement compliance, this unit carries TAA-compliant designation qualifying it for U.S. GSA Schedule purchasing. For a comparable Axient Digital transmitter with ShowLink capability, see the Shure ADX2/B58 at Creation Networks.

Frequently Asked Questions

Why would I choose the X55 band over other frequency bands?
The X55 band (941–960 MHz) operates in upper UHF spectrum that is often less congested than the 470–700 MHz range in markets with heavy broadcast TV usage. AV system designers sometimes specify X55 for installations where lower UHF bands are crowded, though frequency availability varies by region. Always verify X55 is licensed for wireless microphone use in your specific location before purchasing.

What receivers are compatible with this transmitter?
The AD2/KSM8 X55 requires Shure Axient Digital receivers operating in the X55 frequency band, including the AD4D, AD4Q, ADX4, and ADX4D. Both transmitter and receiver must be in the same frequency band for proper system operation.

What does TAA compliant mean for this transmitter?
TAA compliance means this unit qualifies for U.S. federal procurement under GSA Schedule and applicable contract vehicles. Government agencies, educational institutions, and contractors on federal projects can purchase this transmitter through compliant procurement channels.

Can I swap the KSM8 capsule for a different type?
Yes. The AD2 uses an interchangeable capsule system. The KSM8 Dualdyne dynamic capsule can be replaced with other Shure capsules including the KSM9, KSM9HS, SM58, Beta 87A, and Beta 87C, allowing the transmitter body to serve multiple applications.

What are the battery and charging options?
The AD2 accepts 2x AA alkaline batteries for up to 8 hours of operation. The Shure SB900A rechargeable battery (sold separately) provides up to 9 hours. Shure SBC220 and SBC840 networked chargers support remote battery monitoring via Wireless Workbench 6 for large installations.

What warranty coverage applies?
Shure provides a limited 2-year manufacturer warranty. Contact Creation Networks for commercial installation support and warranty registration assistance.
