Shure ULXD6/C Digital Wireless Cardioid Boundary Microphone Transmitter (Black) - ULXD6/C=-J50A

Product Overview

The Shure ULXD6/C is a wireless cardioid boundary microphone transmitter for the ULX-D digital wireless system, supplied in the J50A frequency band. Its low-profile boundary form factor is designed for tabletop use in boardrooms, conference rooms, and events where wired microphones are impractical. The cardioid pattern focuses on the talker in front of it and rejects off-axis sound, which helps in rooms with multiple microphones or higher ambient noise.

Product Description

The ULXD6/C combines the discretion of a boundary microphone with the reliability of ULX-D digital wireless, delivering AES-256 encrypted transmission for secure meetings in corporate and government spaces. Paired with a ULX-D or QLX-D digital receiver, it provides low latency and a long transmission range of up to 300 feet (100 meters), supporting reliable performance in large conference centers and convention spaces. The cardioid polar pattern suits applications where talkers are seated in fixed positions and where rejecting room noise and adjacent sources improves intelligibility. For large multi-channel deployments, up to 200 ULXD6 transmitters can operate with a single pair of receiving antennas, simplifying RF infrastructure. Optional SB900C rechargeable batteries provide up to 12 hours of run-time, and the unit can be charged in a networked docking station for fleet management.

Frequently Asked Questions

What is the difference between the cardioid and omnidirectional ULXD6?
The cardioid ULXD6/C focuses on the talker in front of it and rejects off-axis sound, which helps in noisier rooms or where microphones are close together; the omnidirectional version picks up evenly from all directions for participants seated around a table.

Which receivers does it work with?
It pairs with ULX-D or QLX-D digital receivers such as the ULXD4Q.

How long does the battery last?
Optional SB900C rechargeable batteries provide up to 12 hours of run-time and can be charged in a networked docking station.

How many can I run on one system?
Up to 200 ULXD6 transmitters can operate with a single pair of receiving antennas, which suits large multi-channel installations.

Is the audio secure?
Yes. ULX-D provides AES-256 encryption for secure transmission in corporate and government environments.
