Shure AD4DUS – Axient Digital Two-Channel Wireless Receiver with US Power Supply

Product Overview

The Shure AD4DUS is the US power supply-equipped configuration of the Axient Digital AD4D two-channel wireless receiver, the system core for professional-grade Axient Digital deployments. Supporting all AD series and ADX series transmitters, the AD4DUS Axient Digital wireless receiver delivers wide tuning, low latency, High Density mode, and networked control in a 1RU rack-mount chassis. Available in A (470–636 MHz), B (606–810 MHz), and C (750–960 MHz) frequency bands, it sets a standard for spectral efficiency in demanding commercial AV, broadcast, and live event environments.

Product Description

The AD4DUS provides two independent receiver channels, each with its own RF diversity, audio processing, and output. High Density mode enables up to 47 active transmitters in a single 6 MHz TV channel (up to 63 in an 8 MHz channel), delivering the channel density required for large-scale government, broadcast, and conference deployments where spectrum is constrained. Networked control and signal routing options integrate the AD4DUS into complex AV infrastructure managed via Wireless Workbench 6, enabling frequency coordination, live RF monitoring, and remote gain control from a centralized control room. Compatible transmitters include the Shure AD2/K9B Axient Digital Handheld Transmitter and the Shure QTAD10PS Q5X PlayerMic Bodypack Transmitter.

Key Features

• Two Independent Receiver Channels in 1RU — Houses two complete Axient Digital receivers in a single rack unit, compatible with all AD and ADX series transmitters for flexible wireless system design.
• High Density Mode — Enables up to 47 simultaneous active transmitters in a 6 MHz TV channel (up to 63 in 8 MHz), supporting the highest-density commercial AV and broadcast wireless deployments.
• Wide Tuning Bandwidth — Broad tuning range across the selected frequency band maximizes frequency coordination flexibility in contested RF environments.
• Low Latency — Minimized audio processing delay is critical for live performance and broadcast applications where synchronization with video and confidence monitoring is essential.
• Networked Control and Signal Routing — Integrates with Wireless Workbench 6 and AV control infrastructure for centralized remote management, frequency coordination, and live RF monitoring.
• Compatible with All AD and ADX Series Transmitters — Accepts handheld, bodypack, boundary, and specialty transmitters from the full Axient Digital product family for complete system flexibility.
• US Power Supply Included — Configured with a US-standard locking power supply for immediate deployment without additional power accessories.
• Multiple Frequency Bands — Available in A (470–636 MHz), B (606–810 MHz), and C (750–960 MHz) bands to match regional spectrum availability and RF environment requirements.

Technical Specifications

Frequently Asked Questions

What transmitters are compatible with the AD4DUS?
The AD4DUS is compatible with all Axient Digital AD series transmitters (AD1, AD2, AD3, QTAD10P) and ADX series transmitters (ADX1, ADX2, ADX3). It is not compatible with ULX-D, QLX-D, or PSM system transmitters.

What is the difference between the AD4D and AD4DUS?
The AD4DUS (US) includes a US-standard locking power supply with the receiver. The base AD4D comes without a power supply and requires a separately purchased power option. Both units are otherwise identical in specifications and performance.

How does High Density mode work?
High Density mode compresses per-channel RF bandwidth to fit more simultaneous transmitters into the same spectrum. In HD mode, the AD4DUS supports up to 47 active transmitters per 6 MHz TV channel (or up to 63 per 8 MHz), enabling large-scale deployments in government, conference, and broadcast environments where spectrum is limited.

Does the AD4DUS support Wireless Workbench 6?
Yes. The AD4DUS integrates with Wireless Workbench 6 over Ethernet for centralized frequency coordination, RF level monitoring, remote gain and mute control, and system management in multi-room or multi-venue installations.

Is the AD4DUS suitable for permanent rack installation?
Yes. The 1RU chassis is designed for permanent rack integration in broadcast facilities, commercial AV installations, government spaces, and conference centers. Remote antenna deployment with compatible Shure antenna distribution systems (e.g., UA845UWB) is recommended for optimal RF coverage in larger or multi-zone facilities.
