Shure AD1TA=-X55 – Axient Digital Bodypack Transmitter, TA4M, X55 (TAA)

Product Overview

The Shure AD1 Axient Digital bodypack transmitter (AD1TA=-X55) operates in the X55 band (941–960 MHz) with a TA4M (4-pin mini XLR) connector and full TAA compliance. Operating in the 941–960 MHz range, this transmitter provides access to spectrum above the primary UHF TV broadcast bands, offering deployment options in environments where lower-UHF spectrum is heavily congested or locally restricted. AES-256 encryption, High Density mode, and Wireless Workbench 6 integration make it a professional-grade component for commercial AV system designers and integrators working on government, broadcast, and corporate deployments. Pair it with the Shure AD4Q-US Axient Digital Four-Channel Receiver for a complete Axient Digital wireless system in the X55 band.

Product Description

The AD1TA=-X55 professional wireless bodypack transmitter for AV integration operates in the X55 band (941–960 MHz), a frequency range above the standard UHF TV broadcast window that may provide cleaner or more accessible spectrum in certain markets. The TA4M (4-pin mini XLR) connector offers the broadest lavalier and headset microphone compatibility across professional AV manufacturers. With selectable RF output power (2/10/35 mW), Automatic Gain Control, and frequency/power lockout functions, the AD1 supports disciplined operation in professional live event and commercial AV environments. Wireless Workbench 6 integration enables centralized spectrum management, remote battery monitoring, and multi-system coordination. The unit ships TAA-compliant, qualifying for government procurement. Note: before deploying wireless equipment in the 941–960 MHz range, verify local regulatory permissions and frequency coordination requirements in your market.

Key Features

• X55 Band Operation (941–960 MHz) — Operates above the standard UHF TV broadcast spectrum, offering spectrum access in environments where lower-UHF bands are congested or subject to local regulatory restrictions. Verify local frequency authorization before deployment.
• 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 additional adapters.
• High Density Mode — Enables high-density simultaneous channel operation for commercial AV deployments requiring many wireless channels within a constrained spectrum environment.
• AES-256 Encryption — Military-grade transmission security required for government, enterprise, and legal AV environments mandating audio confidentiality.
• Selectable RF Output Power (2/10/35 mW) — Three levels allow the integrator to optimize the balance between transmission range (up to 100 m line-of-sight) and channel density for the specific deployment environment.
• Automatic Gain Control — Manages mic input levels in real time without manual adjustment, ensuring consistent signal quality across varied presenters and performers.
• Rechargeable Battery Support — Compatible with the optional Shure SB900A rechargeable Li-ion battery for up to 9 hours runtime, with networked docked charging via SBC220 or SBC840 chargers.
• IR Sync — Infrared one-touch synchronization with compatible Axient Digital receivers accelerates multi-channel system configuration in commercial AV installations.
• Wireless Workbench 6 Compatible — Centralized RF coordination, spectrum scanning, remote battery monitoring, and multi-system configuration management for enterprise-scale commercial deployments.
• Removable 1/4-Wave Antenna — Field-replaceable whip antenna for maintenance and RF optimization without unit downtime.
• Selectable Latency (2–2.9 ms) — Low-latency options for IEM-linked performers and presentation environments requiring audio-video synchronization.
• TAA-Compliant — Eligible for federal government procurement under GSA schedules and Trade Agreements Act contract vehicles.

Typical Applications

• Government and federal facilities requiring TAA-compliant wireless audio with AES-256 encryption where X55 band spectrum is available
• Commercial AV installations in markets where the 941–960 MHz range provides better spectrum access than lower UHF bands
• Broadcast studio environments configured for 900+ MHz band operation
• Corporate conference room and boardroom deployments requiring encrypted, centrally managed wireless infrastructure
• House of worship and multi-purpose room installations using X55 band for spectrum diversity across multiple wireless systems
• All-hands room and training room AV systems with multiple simultaneous presenter microphones managed via Wireless Workbench 6
• Commercial auditorium deployments requiring scalable wireless microphone infrastructure above the standard UHF broadcast window

Frequently Asked Questions

Why would I choose the X55 band over G57 or K54?
The X55 band (941–960 MHz) operates above the standard UHF TV broadcast window, which can provide cleaner available spectrum in markets with heavy lower-UHF broadcast activity. It is also useful when spectrum coordination across multiple wireless systems requires band diversity. Always verify local regulatory permissions and spectrum availability before deploying equipment in the 941–960 MHz range, as regulations vary by market.

Is the X55 band legal to use in the United States?
Operation in the 941–960 MHz range is subject to FCC regulation and may require coordination or licensing depending on the specific frequencies and power levels used. Work with your RF coordinator and refer to current FCC frequency allocation rules before deploying the AD1TA=-X55. Creation Networks recommends verifying compliance with all applicable regulations for your installation location.

What microphones are compatible with the TA4M connector?
The TA4M (4-pin mini XLR) is compatible with professional lavalier and headset microphones from a wide range of manufacturers. The AD1 provides 5V bias/plug-in power only — not phantom power. Confirm microphone compatibility before purchase.

What Axient Digital receivers work with the X55 band?
The AD1TA=-X55 requires an Axient Digital receiver configured for the X55 band (941–960 MHz). Confirm your receiver's frequency band before purchasing. The unit is not compatible with ULX-D, SLX-D, or BLX receivers.

Does the AD1TA=-X55 support rechargeable batteries?
Yes. The AD1 accepts the optional Shure SB900A rechargeable lithium-ion battery for up to 9 hours of runtime. Standard 2× AA alkaline batteries provide up to 8 hours as a practical fallback option.

Is this product TAA-compliant?
Yes. The AD1TA=-X55 is TAA-compliant and eligible for federal 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. Contact Creation Networks for warranty and support services.
