Shure AD1TA=-K54 – Axient Digital Bodypack Transmitter, TA4M, K54 (...
Product Overview
The Shure AD1 Axient Digital bodypack transmitter (AD1TA=-K54) operates in the K54 band (606–663 MHz) with a TA4M (4-pin mini XLR) connector and TAA compliance. This commercial wireless microphone transmitter delivers 146 MHz of ultrawide UHF tuning, AES-256 encryption, and High Density mode for large-scale professional wireless deployments in government facilities, broadcast studios, corporate AV installations, and commercial meeting spaces. The K54 band provides spectrum options above the primary lower-UHF congestion zone, and the TA4M connector offers the widest lavalier and headset microphone compatibility in the industry. Pair with the Shure AD4Q-US Axient Digital Four-Channel Receiver for a complete Axient Digital wireless system.
Product Description
The AD1TA=-K54 is a professional Axient Digital bodypack transmitter for commercial AV integration, combining the industry-standard TA4M input with K54 band operation (606–663 MHz). This frequency range sits above the denser lower-UHF broadcast congestion and is well-suited for deployments requiring cleaner spectrum access in urban and high-density environments. With selectable RF output power (2/10/35 mW), automatic Gain Control, and support for standard and High Density transmission modes, the AD1 provides the channel flexibility and RF performance required by professional integrators. Wireless Workbench 6 compatibility enables centralized spectrum coordination, remote battery monitoring, and multi-system management from a single platform. The unit ships TAA-compliant, qualifying for government and federal agency procurement.
Key Features
- K54 Band Operation (606–663 MHz) — Operates above the primary lower-UHF broadcast congestion, offering cleaner available spectrum for commercial deployments in markets with heavy lower-band TV activity.
- TA4M (4-Pin Mini XLR) Connector — The most universally compatible professional wireless input connector, supporting lavalier and headset microphones from virtually all major AV manufacturers without adapters.
- 146 MHz Ultrawide UHF Tuning Range — Provides wide frequency agility for interference avoidance and channel coordination in complex commercial wireless environments.
- High Density Mode — Allows high-density simultaneous channel deployment in commercial spaces, auditoriums, government facilities, and broadcast studios where many wireless channels operate concurrently.
- AES-256 Encryption — Secure transmission for government, enterprise, and legal AV environments requiring audio confidentiality.
- Selectable RF Output Power (2/10/35 mW) — Three selectable power levels provide precise control over the range-vs-density tradeoff for any commercial installation scenario.
- Automatic Gain Control — Real-time input level management ensures consistent signal quality across multiple presenters or performers without manual gain adjustments.
- Rechargeable Battery Option — Compatible with the optional Shure SB900A rechargeable Li-ion battery for up to 9 hours runtime, with networked charging via SBC220 or SBC840 chargers.
- IR Sync — Infrared channel synchronization with Axient Digital receivers reduces multi-channel setup time in large AV installations.
- Wireless Workbench 6 Compatible — Centralized RF coordination, spectrum scanning, real-time battery monitoring, and remote configuration for enterprise commercial deployments.
- Removable 1/4-Wave Antenna — Field-replaceable whip antenna for maintenance and directional RF optimization without unit downtime.
- TAA-Compliant — Eligible for federal government procurement under GSA schedules and Trade Agreements Act contract vehicles.

Frequently Asked Questions
Why choose the K54 band over the G57 band?
The K54 band (606–663 MHz) operates above the primary lower-UHF broadcast congestion found in the 470–600 MHz range. In urban markets or venues near active TV broadcast infrastructure, the K54 band may offer cleaner available spectrum. Always verify local frequency availability using Shure Wireless Workbench 6 or the Shure Frequency Finder before finalizing band selection.
What microphones are compatible with the TA4M connector?
The TA4M (4-pin mini XLR) is the most universally supported connector in professional wireless. Compatible lavalier and headset microphones are available from Shure, DPA, Countryman, Audio-Technica, Tram, and many others. This connector provides 5V bias/plug-in power — not phantom power. Confirm microphone compatibility with your specific model before purchase.
What Axient Digital receivers are compatible with this transmitter?
The AD1TA=-K54 is compatible with all Axient Digital receivers, including the AD4D (dual-channel) and AD4Q (four-channel). Frequency bands must match: use a receiver configured for the K54 band (606–663 MHz). The transmitter is not compatible with ULX-D or SLX-D receivers.
Does the AD1 support remote battery monitoring?
Yes. When paired with Shure Wireless Workbench 6 and compatible networked charging hardware (SBC220 or SBC840), the AD1 supports remote battery status monitoring with precision readout in hours and minutes. This is valuable for IT managers and AV system designers overseeing multi-channel commercial wireless deployments.
Is this product eligible for government procurement?
Yes. The AD1TA=-K54 is TAA-compliant and eligible for procurement under GSA schedules and other federal contract vehicles requiring Trade Agreements Act compliance.
