Shure AD2TA/K9B=-K54 Digital Handheld Wireless Microphone Transmitter with KSM9 Capsule (K54: 606 to 663 MHz, Black) (TAA-Compliant)

Product Overview

The Shure AD2/KSM9 (TAA-Compliant) in the K54 frequency band (606–663 MHz) is a professional Axient Digital handheld wireless transmitter paired with the KSM9 premium condenser capsule, designed for commercial AV installations requiring condenser-quality vocal capture in a mid-UHF frequency allocation. The KSM9 condenser capsule with switchable supercardioid and cardioid polar patterns gives AV designers flexibility to optimize gain-before-feedback and off-axis rejection per venue, while the K54 band offers an alternative RF window for markets with congestion in the lower G57 frequencies. TAA compliant for federal procurement eligibility, this transmitter brings AES-256 encryption, High Density mode, and Wireless Workbench 6 integration to commercial AV systems at the Axient Digital tier. Compatible with Shure Axient Digital K54-band receivers (AD4D, AD4Q, ADX4, ADX4D).

Product Description

The KSM9 condenser capsule uses a dual gold-layered, low-mass Mylar diaphragm design that captures vocal nuance with exceptional frequency consistency. Its field-switchable polar pattern — between supercardioid and cardioid — provides on-site control over gain-before-feedback and off-axis rejection, which is particularly valuable in multi-speaker conference rooms, government hearing rooms, and multipurpose commercial spaces with variable acoustic conditions. The AD2 transmitter body delivers wide tuning across the K54 band (up to 184 MHz), selectable RF output at 2, 10, or 35 mW, and AES-256 encryption on every unit. The moisture-resistant aluminum housing is lightweight and built for daily commercial deployment, with a backlit LCD providing real-time status for frequency, channel, RF output, and battery level. IR sync enables fast pairing with K54-band Axient Digital receivers during commissioning, and Wireless Workbench 6 integration supports centralized spectrum management across large multi-transmitter installations. For an Axient Digital transmitter with ShowLink capability, see the Shure ADX2/B58 at Creation Networks.

Key Features

• Switchable Polar Pattern (Supercardioid / Cardioid) — Field-adjustable polar pattern allows on-site optimization for gain-before-feedback or off-axis rejection based on room acoustics and speaker placement.
• K54 Band (606–663 MHz) — Mid-UHF frequency allocation providing an alternative RF window in markets where lower UHF bands are heavily utilized by broadcast TV operations.
• Axient Digital Compatible — Integrates with Shure Axient Digital K54-band receivers for enterprise-scale wireless microphone management via Wireless Workbench 6.
• AES-256 Encryption — Military-grade encryption standard on all AD2 units, protecting transmission in government, legal, and sensitive commercial meeting environments.
• High Density Mode — Maximizes simultaneous channel count per RF band for large conference rooms, all-hands spaces, and multi-room commercial installations.
• Selectable RF Output (2/10/35 mW) — Three RF output levels enable AV designers to optimize for range or channel density per the installation requirements.
• Moisture-Resistant Aluminum Housing — Lightweight, durable construction engineered for daily commercial-grade use across demanding AV environments.
• 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 swapped for other Shure capsules (KSM8, KSM9HS, SM58, Beta 87A, and more) without tools, increasing deployment flexibility.
• TAA Compliant — Qualifies for U.S. federal government procurement under the GSA Schedule and applicable federal contract vehicles.

Technical Specifications

Frequently Asked Questions

What receivers are compatible with this K54-band transmitter?
The AD2/KSM9 K54 requires Shure Axient Digital receivers in the K54 frequency band, including the AD4D, AD4Q, ADX4, and ADX4D. Both transmitter and receiver must operate in the same frequency band. Always verify K54 is available and licensed for wireless microphone use in your location before purchasing.

How does the KSM9's switchable polar pattern benefit commercial AV installations?
The KSM9's switchable pattern allows audio engineers to select supercardioid for tighter rejection of off-axis sound and higher gain-before-feedback, or cardioid for a wider acceptance angle accommodating presenters who move. This in-field adjustability is particularly useful during commissioning of conference rooms, training spaces, and government chambers where speaker positioning varies.

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

Can the KSM9 capsule be swapped for a different Shure capsule?
Yes. The AD2 uses an interchangeable capsule design. The KSM9 can be replaced with other Shure capsules including the KSM8, KSM9HS, SM58, Beta 87A, and Beta 87C, allowing the transmitter body to be repurposed across different deployment scenarios.

What are the battery and charging options?
The AD2 accepts 2x AA alkaline batteries for up to 8 hours or the Shure SB900A rechargeable battery (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 assistance.
