Shure AD1TA=-G57 – Axient Digital Bodypack Transmitter, TA4M, G57 (...
Product Overview
The Shure AD1 Axient Digital bodypack transmitter (AD1TA=-G57) operates in the G57 band (470–616 MHz) with a TA4M (4-pin mini XLR) connector and full TAA compliance. With 146 MHz of ultrawide UHF tuning, AES-256 encryption, and High Density mode, the AD1 is a proven component for Axient Digital wireless microphone deployments in government facilities, broadcast studios, conference rooms, and commercial AV installations. The TA4M input is the most widely compatible connector in the professional wireless microphone industry, supporting the broadest range of lavalier and headset microphones. Pair it with the Shure AD4Q-US Axient Digital Four-Channel Receiver for a complete commercial-grade wireless system.
Product Description
The AD1 professional wireless bodypack transmitter for AV system integration brings together 146 MHz of ultrawide UHF tuning with the industry-standard TA4M (4-pin mini XLR) connector — the most universally supported input across professional lavalier and headset microphone manufacturers. Operating in the G57 band (470–616 MHz), this TAA-compliant transmitter supports up to 47 simultaneous channels per band in standard mode, with High Density mode extending that count for large-venue commercial deployments. Automatic Gain Control stabilizes input levels across varied talent and presenters, while selectable RF output power (2/10/35 mW) lets the integrator balance range and channel density. Wireless Workbench 6 provides centralized RF coordination, spectrum scanning, and remote battery monitoring for IT managers and AV system designers. The aluminum housing is lightweight (155 g without batteries) and moisture-resistant, suited for regular handling in professional AV workflows.
Key Features

- G57 Band Operation (470–616 MHz) — Covers 146 MHz of ultrawide UHF spectrum in the standard professional wireless range, providing strong frequency agility and compatibility with standard UHF antenna distribution infrastructure.
- High Density Mode — Increases simultaneous channel count for large commercial deployments by reducing RF footprint per channel, supporting complex multi-channel wireless systems in auditoriums, broadcast studios, and government facilities.
- AES-256 Encryption — Military-grade security for government, enterprise, and legal AV environments where audio transmission confidentiality is a contractual or regulatory requirement.
- Selectable RF Output Power (2/10/35 mW) — Three power levels allow precise control of the tradeoff between transmission range and channel density for any commercial installation scenario.
- Automatic Gain Control — Manages mic input levels in real time, eliminating manual gain adjustments between different presenters or performers and ensuring consistent signal quality throughout events.
- Rechargeable Battery Support — Accepts the optional Shure SB900A rechargeable Li-ion battery (sold separately) for up to 9 hours runtime with networked docked charging via SBC220 or SBC840 chargers.
- IR Sync — One-touch infrared channel synchronization with Axient Digital receivers reduces multi-channel setup time in large commercial AV installations.
- Wireless Workbench 6 Compatible — Enterprise RF management platform supporting centralized spectrum scanning, remote monitoring, battery status tracking, and configuration management across commercial deployments.
- Removable 1/4-Wave Antenna — Field-replaceable whip antenna allows maintenance and RF optimization without returning the unit to service.
- Selectable Latency (2–2.9 ms) — Ultra-low latency settings support IEM-linked performers and professional presentation environments with audio-video synchronization requirements.
- TAA-Compliant — Qualifies for federal government procurement under GSA schedules and government contract vehicles requiring Trade Agreements Act compliance.
Typical Applications
- Government and federal facilities requiring TAA-compliant audio equipment with AES-256 encrypted wireless transmission

Frequently Asked Questions
What microphones work with the TA4M connector on the AD1TA=-G57?
The TA4M (4-pin mini XLR) is the most broadly supported input connector in professional wireless systems. Compatible lavalier and headset microphones are available from Shure, DPA, Countryman, Sennheiser, Audio-Technica, Tram, and many others. The AD1 provides 5V bias/plug-in power — no phantom power. Confirm microphone compatibility with your specific model before purchase.
Can I use this transmitter with Shure ULX-D receivers?
No. The AD1 is part of the Axient Digital system and is only compatible with Axient Digital receivers (AD4D, AD4Q, etc.). It is not backward-compatible with ULX-D or SLX-D receivers. Verify that your receiver is an Axient Digital model before ordering.
How many simultaneous wireless channels can I deploy with the AD1?
In Standard mode, the Axient Digital system supports up to 47 simultaneous channels per band. High Density mode increases channel count further for large-venue deployments. Actual channel count depends on the RF environment, antenna infrastructure, and system configuration managed through Wireless Workbench 6.
What is the audio frequency response of the AD1?
The AD1 transmits the full audio range captured by the connected microphone. As a transmitter, its audio frequency response is determined by the connected microphone capsule — not the transmitter itself. The system supports professional audio quality suitable for broadcast, AV presentation, and commercial sound reinforcement.
Is the AD1TA=-G57 TAA-compliant for government purchasing?
Yes. This unit is TAA-compliant and eligible for procurement under GSA schedules and other federal contract vehicles requiring Trade Agreements Act compliance.
What warranty does the Shure AD1 carry?
Shure provides a limited 2-year manufacturer warranty. Contact Creation Networks for support and warranty service inquiries.
