Shure ULXD4D Dual-Channel Digital Wireless Receiver

Product Overview

The Shure ULXD4D is a professional dual-channel digital wireless receiver providing two independent channels in a single 1RU rack unit, designed for multi-microphone commercial AV installations, houses of worship, government facilities, and touring live sound. It delivers 24-bit/48 kHz audio on both channels simultaneously, with an expanded tuning range of up to 166 MHz (region dependent), Dante digital audio networking, AES 256-bit encryption, and comprehensive network control via Wireless Workbench 6, AMX, and Crestron—making it the centerpiece of scalable professional wireless infrastructure.

Product Description

The ULXD4D houses two fully independent receivers in a rugged all-metal 1RU chassis with an internal power supply, each channel providing its own XLR output, gain control, and audio/RF LED metering. Dante digital audio networking enables multi-channel audio transport over a single Ethernet cable, critical for installed AV systems requiring centralized audio routing without analog snake runs. RF cascade ports allow distribution of the RF signal to additional units, supporting large antenna infrastructure deployments. High Density mode significantly increases the number of simultaneous channels operable within approximately 30 meters, and bodypack frequency diversity ensures uninterrupted audio for mission-critical wireless applications. The Yamaha device ID simplifies channel patching on CL series digital consoles for performing arts and touring installations. Pair with ULXD2 transmitters such as the Shure ULXD2/B87A to build a complete dual-channel ULX-D wireless system.

Key Features

• Two Independent Digital Wireless Channels in 1RU — Houses two complete receivers in a single rack unit with individual XLR outputs, gain controls, and metering per channel, maximizing rack space efficiency in commercial AV installations.
• Dante Digital Audio Networking — Transmits multiple audio channels over a single Ethernet cable for installed AV systems requiring centralized digital audio routing without analog cabling infrastructure.
• Expanded Tuning Range (Up to 166 MHz) — Provides a wide frequency range for frequency coordination in challenging RF environments at conference centers, convention venues, and campus facilities.
• AES 256-Bit Encryption — Secures both channels of digital audio transmission for government, corporate, legal, and sensitive commercial AV applications.
• RF Cascade Ports — Allow RF signal distribution to additional receiver units from a single antenna pair, supporting large-scale multi-receiver installations without redundant antenna infrastructure.
• High Density Mode — Enables significantly more simultaneous ULX-D channels within approximately 30 meters, essential for high channel-count conference, training room, and event environments.
• Bodypack Frequency Diversity — Ensures continuous, dropout-free audio for mission-critical wireless applications such as simultaneous interpretation, broadcast, and conference keynotes.
• Wireless Workbench 6, AMX/Crestron, and Yamaha CL Integration — Provides comprehensive enterprise AV control via software and hardware control systems, including simplified channel patching on Yamaha CL digital consoles.

Frequently Asked Questions

Q: How does the ULXD4D differ from the ULXD4?
A: The ULXD4D houses two independent channels in 1RU with an internal power supply, Dante audio networking, RF cascade ports, and expanded tuning range up to 166 MHz. The ULXD4 is a half-rack single-channel receiver with an external power supply and 64 MHz tuning range, suited for smaller systems.

Q: Does the ULXD4D support Dante audio networking for installed AV systems?
A: Yes. Dante digital networking allows both audio channels to be routed over a single Ethernet cable to compatible Dante-enabled DSPs, mixers, and audio systems—eliminating analog cabling from the equipment rack to the audio DSP.

Q: How many simultaneous channels can be coordinated with the ULXD4D in High Density mode?
A: High Density mode significantly increases simultaneous channel capacity within approximately 30 meters. The exact number depends on the frequency band and RF environment; Wireless Workbench 6 provides precise frequency coordination analysis for each deployment.

Q: What transmitters are compatible with the ULXD4D?
A: The ULXD4D is compatible with all ULX-D transmitters including ULXD2 handheld, ULXD1 bodypack, ULXD6 boundary microphone, and ULXD8 gooseneck base transmitters. Frequency bands must match.

Q: What warranty applies to the ULXD4D?
A: Shure provides a two-year limited warranty on the ULXD4D. Contact Creation Networks for purchasing assistance or Shure directly for warranty service.
