Shure AD1LEMO3TA=-G57 – Axient Digital Bodypack Transmitter, LEMO3, G57 (TAA)

Product Overview

The Shure AD1 Axient Digital bodypack transmitter (AD1LEMO3TA=-G57) is a professional wireless transmitter for the Axient Digital system, operating in the G57 band (470–616 MHz) with a LEMO3 3-pin connector and full TAA compliance. With 146 MHz of ultrawide UHF tuning range, AES-256 encryption, and High Density mode, this transmitter supports large-scale commercial wireless microphone deployment for integrators and AV system designers working in government spaces, corporate AV installations, and broadcast environments. It integrates directly with the Shure AD4Q-US Axient Digital Four-Channel Receiver and the full Axient Digital ecosystem.

Product Description

Engineered for integrators deploying wireless microphone infrastructure in spectrum-congested environments, the AD1 bodypack transmitter combines a lightweight aluminum housing with selectable RF output power (2/10/35 mW) and support for up to 47 simultaneous channels per band in standard mode — extending further with High Density mode for maximum channel count. The LEMO3 connector supports broadcast-grade lavalier and headset microphones that use the industry-standard 3-pin LEMO interface, making this transmitter a practical choice for corporate broadcast, government AV, and professional recording applications. Automatic Gain Control eliminates manual gain-staging during live events, and frequency/power lockout functions prevent unauthorized changes mid-production. Full integration with Shure's Wireless Workbench 6 software enables centralized RF coordination, real-time battery monitoring, and remote configuration — essential for IT managers and AV system designers overseeing multi-room commercial deployments. Ships TAA-compliant for federal procurement.

Key Features

• 146 MHz Ultrawide UHF Tuning Range — Provides exceptional frequency agility across the G57 band (470–616 MHz), enabling efficient channel coordination and interference avoidance in multi-channel commercial AV installations.
• High Density Mode — Maximizes channel count in congested RF environments, allowing AV system designers to deploy high-density wireless microphone systems in large venues, government spaces, and multi-room facilities.
• AES-256 Encryption — Provides military-grade audio security for government, legal, and enterprise AV deployments where transmission confidentiality is a requirement.
• LEMO3 Connector (3-Pin) — Supports broadcast-grade lavalier and headset microphones using the industry-standard 3-pin LEMO interface, widely used in professional recording and corporate broadcast setups.
• Selectable RF Output Power (2/10/35 mW) — Allows the integrator to balance transmission range (up to 100 m / 328 ft line-of-sight) against channel density as deployment conditions require.
• Automatic Gain Control — Adjusts mic input levels in real time without manual intervention, maintaining consistent signal quality across multiple presenters or performers in commercial event environments.
• Rechargeable Battery Support — Compatible with the optional SB900A rechargeable lithium-ion battery (sold separately) for up to 9 hours of runtime, with intelligent docked charging via SBC220 two-bay or SBC840 eight-bay networked chargers.
• IR Sync — One-touch infrared synchronization with compatible Axient Digital receivers speeds up channel assignment and reduces setup time in multi-channel AV installations.
• Wireless Workbench 6 Compatible — Full integration enables centralized RF coordination, spectrum scanning, real-time battery status monitoring, and remote configuration across enterprise-scale commercial wireless deployments.
• Removable 1/4-Wave Antenna — Field-replaceable whip antenna allows maintenance without unit replacement and supports directional RF optimization for complex installation environments.
• Selectable Latency (2–2.9 ms) — Ultra-low latency options ensure audio-video synchronization for IEM-linked performers and professional presentation applications.
• TAA-Compliant — Qualifies for federal government procurement under GSA schedules and other government contract vehicles.

Typical Applications

• Government and federal facilities requiring TAA-compliant audio equipment with AES-256 encrypted wireless transmission
• Boardroom and executive conference room deployments requiring encrypted, centrally managed wireless microphone infrastructure
• House of worship with high channel-count requirements across simultaneous services and rehearsal spaces
• Broadcast studio environments requiring minimal latency and high-density channel deployment
• Multi-purpose room and all-hands room AV systems supporting varying event configurations from a single wireless infrastructure
• Training room installations with multiple simultaneous presenter microphones managed via Wireless Workbench 6
• Commercial meeting spaces in corporate campuses requiring scalable, spectrum-managed wireless microphone systems

Frequently Asked Questions

Is the AD1LEMO3TA=-G57 compatible with Shure Axient Digital receivers?
Yes. The AD1 is compatible with all Axient Digital series receivers including the AD4D dual-channel and AD4Q four-channel units. Frequency bands must match: this unit operates in the G57 band (470–616 MHz), so it requires an Axient Digital receiver configured for that band.

What microphones work with the LEMO3 connector?
The LEMO3 (3-pin) connector is supported by many professional lavalier and headset microphones from manufacturers including DPA, Countryman, Sennheiser, and others that offer LEMO-compatible terminations. Check your microphone manufacturer's specifications for LEMO3 compatibility. No phantom power is provided — only 5V bias/plug-in power.

Can the AD1 be managed remotely during a live event?
Yes. When used with Shure Wireless Workbench 6 software and compatible network infrastructure, the AD1 supports remote battery monitoring, RF status, and frequency coordination. Frequency and power lockout functions can also be engaged to prevent unauthorized local changes during events.

Does the AD1 support rechargeable batteries?
The AD1 accepts 2× AA alkaline batteries (up to 8 hours) as standard. The optional Shure SB900A rechargeable lithium-ion battery provides up to 9 hours of runtime. Networked charging is available via the SBC220 two-bay or SBC840 eight-bay chargers, which integrate with Wireless Workbench 6 for remote power monitoring.

What is High Density mode and when should I use it?
High Density mode reduces the RF footprint of each channel to allow more simultaneous transmitters to operate in a given bandwidth. Use it when deploying a large number of wireless channels in a limited spectrum environment — such as a convention center, government facility, or multi-stage event. Standard mode maximizes range and signal quality for smaller-scale deployments.

Is this product TAA-compliant for government procurement?
Yes. The AD1LEMO3TA=-G57 carries the TAA-compliant designation, making it eligible for procurement under GSA schedules and other government contract vehicles that require compliance with the Trade Agreements Act.

What is the warranty on the Shure AD1?
Shure provides a limited 2-year manufacturer warranty on the AD1 bodypack transmitter covering defects in materials and workmanship. Contact Creation Networks for warranty service and support options.
