Shure ULXD1 – Digital Wireless Bodypack Transmitter with LEMO3 Connector

Product Overview

The Shure ULXD1 with LEMO3 connector is a digital wireless bodypack transmitter for use with Shure ULX-D and QLX-D wireless receivers, designed for commercial AV applications where a LEMO3 input connector is required for instrument or line-level sources. Featuring AES 256-bit encryption, up to 12 hours of operation with the SB900C rechargeable battery, and a 330 ft (100 m) operating range, the ULXD1 delivers professional digital audio performance suited for commercial conference, government, broadcast, and live production environments. Available in four frequency band configurations: G50, H50, J50A, and X52.

Product Description

The ULXD1 LEMO3 bodypack transmitter is the instrument-input variant of the ULX-D digital wireless system, intended for applications where the source audio signal uses a LEMO3 connector — common in professional broadcast, theater, and performing arts wireless microphone systems where cable retention and low-profile connector form factor are critical. Shure’s proprietary Gain Ranging technology continuously optimizes the transmitter’s dynamic range based on the incoming audio level, reducing the risk of clipping or excessive noise in environments with highly variable signal levels such as live events, houses of worship, and all-hands rooms. The rugged, lightweight aluminum housing withstands the physical demands of daily-use commercial wireless environments. The backlit LCD with navigable menu gives technical staff direct access to frequency, gain, and status information without requiring a laptop or software connection during field deployment. AES 256-bit encryption protects audio transmission in sensitive commercial environments such as government facilities and corporate boardrooms. For ULX-D boundary microphone transmitters compatible with this system, see the Shure ULXD6/C Cardioid Boundary Transmitter.

Frequently Asked Questions

What is a LEMO3 connector and when is the ULXD1 LEMO3 version required?
A LEMO3 is a locking 3-pin connector widely used in professional broadcast and performing arts wireless microphone systems for cable retention and low-profile connection. The ULXD1 LEMO3 variant is required when connecting microphone elements or instrument sources that use LEMO3 terminations, common in theater, broadcast studio, and high-production commercial AV applications.

Is the ULXD1 compatible with QLX-D receivers?
Yes. The ULXD1 is compatible with both ULX-D and QLX-D receivers operating in the same frequency band. Ensure the transmitter frequency band (G50, H50, J50A, or X52) matches the installed receiver’s band assignment.

What battery is recommended for the ULXD1?
The optional Shure SB900C lithium-ion rechargeable battery provides up to 12 hours of operation. The ULXD1 also accepts standard AA alkaline batteries for deployments where rechargeable infrastructure is not available.

Does the ULXD1 support AES encryption?
Yes. The ULXD1 supports AES 256-bit encryption for secure wireless audio transmission, appropriate for government facilities, corporate boardrooms, and other environments requiring audio transmission security.

What is Shure Gain Ranging and how does it benefit commercial deployments?
Shure Gain Ranging is a proprietary technology that continuously adjusts the transmitter’s dynamic range based on incoming signal levels, reducing the risk of audio clipping from unexpectedly loud input events while maintaining clean audio at lower levels. This is particularly valuable in commercial AV environments with varied presenter skill levels and unpredictable input signal behavior.

Can the ULXD1 be monitored and managed remotely?
Yes. When used with ULX-D receivers connected to a network, the ULXD1 transmitter status (battery level, RF signal, channel assignment) can be monitored remotely via Shure Wireless Workbench software or compatible network management platforms used in commercial AV control rooms.
