Shure AD2TA/K9B=-X55 Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule (X55: 941 to 960 MHz, Black) (TAA-Compliant)

Product Overview

The Shure AD2/KSM9 (TAA-Compliant) in the X55 frequency band (941–960 MHz) is a professional Axient Digital handheld wireless transmitter paired with the KSM9 premium condenser capsule, designed for commercial AV deployments that require condenser-quality vocal capture in upper UHF spectrum. The X55 band is frequently specified when lower UHF frequencies are congested, offering AV system designers a cleaner RF window for enterprise wireless microphone installations. The KSM9's switchable supercardioid and cardioid polar patterns provide in-field flexibility, while the Axient Digital platform delivers AES-256 encryption, High Density mode, and Wireless Workbench 6 management. TAA compliant for U.S. federal procurement. Compatible with Shure Axient Digital X55-band receivers (AD4D, AD4Q, ADX4, ADX4D).

Product Description

The KSM9 condenser capsule's dual gold-layered, low-mass Mylar diaphragm captures vocal detail with exceptional consistency across frequencies, making it a preferred choice for high-profile presentations, broadcast applications, and installations where audio quality is the primary specification criterion. Switchable between supercardioid and cardioid patterns, the KSM9 can be tuned on-site to match the acoustic conditions of each specific room. The X55 band (941–960 MHz) operates in upper UHF spectrum outside the broadcast TV range, which can provide cleaner RF operating conditions in urban markets and dense multi-system environments. The AD2 transmitter platform offers wide tuning (up to 184 MHz), selectable RF output at 2, 10, or 35 mW, and AES-256 encryption on every unit, housed in moisture-resistant aluminum construction. IR sync enables fast pairing with Axient Digital X55-band receivers, and Wireless Workbench 6 integration supports centralized monitoring and frequency coordination. For an Axient Digital upgrade path with ShowLink, see the Shure ADX2/B58 at Creation Networks.

Key Features

• KSM9 Premium Condenser Capsule — Dual gold-layered, low-mass Mylar diaphragm delivers high-detail vocal capture with exceptional frequency consistency for demanding commercial AV environments.
• Switchable Polar Pattern (Supercardioid / Cardioid) — Field-adjustable polar pattern allows on-site optimization for gain-before-feedback or off-axis rejection based on venue acoustics and presenter positioning.
• X55 Band (941–960 MHz) — Upper UHF operation outside the broadcast TV band, frequently specified when lower UHF frequencies are congested in dense urban commercial environments.
• Axient Digital Compatible — Integrates natively with Shure Axient Digital X55-band receivers for enterprise-scale wireless microphone management.
• AES-256 Encryption — Military-grade encryption standard on every AD2 unit, protecting audio transmission in government, legal, and sensitive commercial AV installations.
• High Density Mode — Maximizes simultaneous channel count per RF band for large commercial installations with multiple wireless microphone channels.
• Selectable RF Output (2/10/35 mW) — Three output levels allow AV designers to optimize for range or High Density channel capacity.
• Moisture-Resistant Aluminum Housing — Lightweight, durable construction for daily commercial-grade deployment in boardrooms, auditoriums, and government facilities.
• Rechargeable Battery Support — Compatible with Shure SB900A lithium-ion battery (sold separately) for up to 9 hours of operation with precision hour/minute metering.
• Interchangeable Capsule Design — KSM9 capsule can be replaced with other Shure capsules (KSM8, KSM9HS, SM58, Beta 87A) without tools.
• TAA Compliant — Qualifies for U.S. federal government procurement under the GSA Schedule and applicable federal contract vehicles.

Technical Specifications

Frequently Asked Questions

Why would I specify the X55 band for this installation?
The X55 band (941–960 MHz) operates in upper UHF spectrum outside the broadcast TV band, which can offer cleaner RF operating conditions in markets where lower UHF frequencies (470–700 MHz) are congested. It is frequently specified in urban commercial deployments or where TV broadcast interference is a documented concern. Verify X55 is available and licensed for wireless microphone use in your geographic area before purchasing.

What receivers are compatible with the X55-band AD2/KSM9?
This transmitter requires Shure Axient Digital receivers in the X55 frequency band, including the AD4D, AD4Q, ADX4, and ADX4D. Transmitter and receiver must be in the same frequency band for system operation.

How does the KSM9 condenser capsule compare to a dynamic capsule in commercial AV?
The KSM9 condenser capsule captures greater vocal detail and nuance than a dynamic capsule, with a dual gold-layered Mylar diaphragm that provides exceptional frequency consistency. Condenser capsules are generally preferred for installations where audio quality is the primary specification driver. Dynamic capsules may be specified where extreme handling noise rejection or robustness is the priority.

What does TAA compliant mean for this transmitter?
TAA compliance qualifies this unit for U.S. federal government procurement under GSA Schedule and applicable contract vehicles. Government agencies and federal contractors can include this transmitter in compliant wireless system bids.

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

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