Shure AD1LEMO3TA=-K54 – Axient Digital Bodypack Transmitter, LEMO3, K54 (TAA)

Product Overview

The Shure AD1 Axient Digital bodypack transmitter (AD1LEMO3TA=-K54) operates in the K54 band (606–663 MHz) with a LEMO3 3-pin connector and full TAA compliance. Delivering 146 MHz of ultrawide UHF tuning range, AES-256 encryption, and High Density mode, this commercial wireless microphone transmitter is purpose-built for integrators deploying professional wireless microphone infrastructure in government spaces, broadcast studios, and corporate AV environments. It pairs directly with the Shure AD4Q-US Axient Digital Four-Channel Receiver and the broader Axient Digital platform.

Product Description

The AD1 professional wireless bodypack transmitter for commercial installation operates in the K54 band (606–663 MHz), a frequency range well-suited for deployments that need to avoid the primary TV broadcast congestion in the lower UHF spectrum. The LEMO3 connector provides compatibility with broadcast-grade lavalier and headset microphones that use the industry-standard 3-pin LEMO interface. Selectable RF output power (2/10/35 mW), Automatic Gain Control, and frequency/power lockout functions ensure consistent, controlled operation in live production environments. Wireless Workbench 6 integration provides centralized RF coordination, spectrum management, and remote battery monitoring — a practical necessity for IT managers and facilities staff overseeing multi-room commercial wireless deployments. The unit ships TAA-compliant for government and federal procurement requirements.

Key Features

• K54 Band Operation (606–663 MHz) — Operates in a frequency range that avoids much of the lower-band TV broadcast congestion, offering cleaner spectrum options for commercial AV deployments in dense urban and multi-venue environments.
• 146 MHz Ultrawide UHF Tuning Range — Provides exceptional frequency agility within the K54 band, supporting aggressive interference avoidance and coordination of large multi-channel wireless systems.
• High Density Mode — Maximizes simultaneous channel count for large-scale wireless deployments in auditoriums, government facilities, broadcast studios, and multi-room commercial spaces.
• AES-256 Encryption — Standard military-grade transmission security for government, legal, and enterprise AV environments where audio confidentiality is mandated.
• LEMO3 Connector (3-Pin) — Supports broadcast-standard lavalier and headset microphones using the industry-standard LEMO interface without adapters, streamlining professional microphone integration.
• Selectable RF Output Power (2/10/35 mW) — Three power levels enable the AV system designer to tune the balance between transmission range and channel density based on the specific deployment environment.
• Automatic Gain Control — Continuously adjusts mic input levels during live events, ensuring consistent signal quality without manual gain adjustments between presenters or performers.
• Rechargeable Battery Support — Works with the optional SB900A rechargeable lithium-ion battery for up to 9 hours runtime, with networked charging via SBC220 or SBC840 units integrated into Wireless Workbench 6.
• IR Sync — Infrared one-touch synchronization with Axient Digital receivers speeds up multi-channel system setup and reduces configuration time in large AV installations.
• Wireless Workbench 6 Compatible — Enterprise-grade RF coordination platform for centralized spectrum scanning, real-time monitoring, remote configuration, and battery status management.
• Removable 1/4-Wave Antenna — Field-replaceable whip antenna supports both standard operation and customized RF optimization without returning the unit for service.
• TAA-Compliant — Eligible for federal procurement under GSA schedules and government contract vehicles requiring Trade Agreements Act compliance.

Typical Applications

• Government and federal facilities requiring TAA-compliant wireless audio with AES-256 encrypted transmission in the K54 band

Frequently Asked Questions

What frequency band does the AD1LEMO3TA=-K54 operate in?
This unit operates in the K54 band, covering 606–663 MHz. The K54 band sits above the primary lower-UHF TV broadcast congestion, offering cleaner spectrum options in many markets. Confirm local frequency availability before deployment using Shure's Wireless Workbench 6 or the Shure Frequency Finder tool.

What microphones are compatible with the LEMO3 connector?
The LEMO3 (3-pin) input supports professional lavalier and headset microphones from manufacturers including DPA, Countryman, and others that produce LEMO-compatible terminations. Note that this connector provides 5V bias/plug-in power only — no phantom power is supplied.

Can I use the AD1 with AA batteries in the field?
Yes. The AD1 accepts 2× standard AA alkaline batteries for up to 8 hours of operation, providing a practical fallback option when charging infrastructure is unavailable. The optional Shure SB900A rechargeable Li-ion battery extends runtime to up to 9 hours and supports networked docked charging.

How does High Density mode affect channel count and range?
High Density mode increases the number of simultaneous channels per band by reducing the RF footprint per channel. This is beneficial for large commercial deployments with many simultaneous wireless microphones. It requires an Axient Digital receiver that also supports High Density mode. Transmission range may be reduced in High Density mode compared to Standard mode.

Is this product TAA-compliant for federal procurement?
Yes. The AD1LEMO3TA=-K54 is TAA-compliant and qualifies for procurement under GSA schedules and other government contract vehicles requiring Trade Agreements Act compliance.

What warranty does the Shure AD1 carry?
Shure provides a limited 2-year manufacturer warranty on the AD1 bodypack transmitter. Contact Creation Networks for warranty claims and support options.
