Shure AD4DUSTA=-A Axient Digital Two-Channel Wireless Receiver (A: 470 to 636 MHz) (TAA-Compliant)

Product Overview

The Shure AD4DUSTA=-A is a TAA-compliant, two-channel Axient Digital wireless receiver for commercial AV deployments in government facilities, broadcast studios, and enterprise conference environments. Operating in Band A (470–636 MHz), this 1U rack-mount receiver includes a US power supply, 1/2-wave wideband antennas, BNC coaxial RF cables, RF cascade cable, and Ethernet cables — everything needed to bring up a new Axient Digital receiver position from scratch. Dante, AES3, and AES67 digital audio outputs connect directly to IP-based AV infrastructure without additional adapters.

Product Description

The AD4D supports two independent wireless audio channels in a single 1U rack space. Band A (470–636 MHz) provides extensive spectrum for frequency coordination across multi-channel wireless deployments in RF-dense environments. High Density (HD) mode compresses channel spacing to 125 kHz, supporting up to 47 simultaneous active transmitters in a single 6 MHz TV channel — a requirement for high-channel-count installations in legislative facilities, convention centers, and large corporate campuses. AES-256 encryption secures all wireless audio channels to meet security requirements for federal government facilities and secure boardrooms. The AD4DUSTA=-A is compatible with all Shure AD and ADX series transmitters, giving AV designers flexibility to mix handheld, bodypack, boundary, and gooseneck transmitter form factors within the same system. For a four-channel option in the same frequency band, see the Shure AD4Q-DCTA=-A Four-Channel Receiver.

Key Features

• Two Independent Wireless Channels in 1U — Supports two simultaneous wireless microphone channels from a single rack unit, preserving rack space in commercial AV system builds.
• Band A: 470–636 MHz Tuning Range — Broad spectrum coverage in Band A for frequency coordination across multi-channel wireless deployments in RF-dense environments.
• Includes US Power Supply and Mounting Accessories — Ships with a US-spec AC power supply, 1/2-wave wideband antennas, BNC RF cables, RF cascade cable, and Ethernet cables for complete system commissioning from a new rack position.
• High Density (HD) Mode — Narrows channel spacing to 125 kHz, supporting up to 47 active transmitters per 6 MHz TV channel for high-channel-count installations.
• Dante, AES3, and AES67 Digital Audio Outputs — Native integration with Dante-enabled IP audio networks and AES3/AES67 digital signal paths, compatible with leading DSPs and mixing platforms.
• AES-256 Encryption — Applies government-grade encryption to all wireless audio channels, meeting security standards for federal facilities and secure commercial spaces.
• Interference Management with Automatic Frequency Switching — Detects RF interference and can automatically switch to a clean frequency, reducing dropout risk in congested spectrum.
• 60 dB Gain Adjustment Range — Gain adjustable from -18 to +42 dB in 1 dB steps, compatible with both mic-level and line-level inputs on DSPs, mixers, and amplifiers.
• 120 dB Dynamic Range (XLR) / 130 dB (Dante/AES3) — Transparent digital audio with ample headroom for high-SPL sources without audible compression or clipping artifacts.
• Four-Port Network Switch Built In — Operates in Switched or Split/Redundant mode for flexible integration into existing AV network architectures.
• Wireless Workbench and Control System Integration — Compatible with Shure Wireless Workbench software and mobile app; supports AMX, Crestron, and third-party control systems.
• TAA Compliant — Meets Trade Agreements Act requirements for U.S. federal government procurement under GSA schedules and agency contracts.

Typical Applications

• Government space — TAA compliance and AES-256 encryption support wireless audio in federal courtrooms, legislative chambers, and secured government conference facilities.
• Broadcast studio — 130 dB digital dynamic range and sub-3 ms latency support live production, news studio, and broadcast AV applications.
• Auditorium — HD mode supports large-scale wireless deployments in performing arts centers, lecture halls, and multi-use auditoriums.
• Boardroom — Dante integration and network control allow wireless microphone management in enterprise boardrooms and executive conference suites.
• House of worship — Wide tuning range and interference management support reliable wireless audio in large worship venues with complex RF environments.
• Commercial meeting space — Scalable channel deployment fits multi-room wireless systems in hotels, convention centers, and corporate campuses.

Frequently Asked Questions

What is the difference between the AD4DUSTA=-A and the AD4DNPTA=-A?

Both are the same AD4D two-channel receiver in Band A. The AD4DUSTA=-A includes the US power supply, 1/2-wave wideband antennas, BNC RF cables, RF cascade cable, AC power cable, and Ethernet cables. The AD4DNPTA=-A ships without accessories and is intended for integration into an existing Axient Digital rack where power and cabling are already in place.

What transmitters are compatible with the AD4DUSTA=-A?

This receiver is compatible with all Shure AD series and ADX series transmitters in Band A (470–636 MHz), including handheld (AD2), bodypack (AD1), boundary, gooseneck, and instrument transmitters.

Does this receiver work on existing Dante networks?

Yes. The AD4D includes a 4-port network interface supporting Dante primary and secondary streams. It operates in Switched mode or Split/Redundant mode to match existing network architecture.

What does TAA compliance mean for procurement?

TAA compliance confirms the product was manufactured or substantially transformed in a country covered by a U.S. Trade Agreement. This is required for products purchased under GSA schedules and most federal AV contracts without requesting a waiver.

When should I use High Density mode versus Standard mode?

High Density mode suits high-channel-count deployments where transmitters operate within 6 to 60 meters of receivers. Standard mode is preferred for fewer channels or longer-range installations at higher RF power.

Can gain and mute be controlled remotely?

Yes. Gain, mute, frequency, and RF power can all be controlled remotely via Shure Wireless Workbench software, the Wireless Workbench Mobile app, or AMX/Crestron commands over the network.

What is the warranty on this receiver?

Shure provides a two-year manufacturer warranty on the AD4D. Purchasing through Creation Networks, an authorized Shure reseller, ensures full warranty coverage.
