Shure ULXD6/C Digital Wireless Cardioid Boundary Microphone Transmitter (White)

Product Overview

The Shure ULXD6/C is a professional digital wireless cardioid boundary microphone transmitter in a white finish, designed for tabletop conference room, boardroom, and meeting venue applications where a directional wireless microphone is preferred over omnidirectional pickup. It integrates with ULX-D and QLX-D digital receiver systems to deliver very low latency audio across transmission distances up to 300 feet (100 meters), making it well-suited for commercial AV deployments in government facilities, corporate meeting spaces, and conference centers where wired microphones are impractical.

Product Description

The ULXD6/C cardioid boundary capsule focuses pickup in a single direction, providing better off-axis rejection than the omnidirectional ULXD6/O—making it the preferred choice for single-speaker applications, lecterns, and directional tabletop placements where rejecting room noise or adjacent audio sources improves intelligibility. The white finish suits installations in conference rooms and meeting spaces with white or light-colored furnishings and AV equipment. Very low system latency enables simultaneous live sound reinforcement alongside wireless transmission in large meeting venues. The configurable mute button supports Toggle, Push-to-Mute, Push-to-Talk, or disabled operation to match specific meeting workflow requirements. Optional SBC250, SBC450, and SBC850 networked charging stations support fleet management in multi-transmitter commercial deployments.

Key Features

Frequently Asked Questions

Q: What is the difference between the ULXD6/C and ULXD6/O?
A: The ULXD6/C has a cardioid capsule that focuses pickup in one direction with better off-axis rejection, suited for single-speaker or directional tabletop scenarios. The ULXD6/O has an omnidirectional capsule that picks up audio from all directions, suited for round-table conference room applications where all participants need equal coverage.

Q: What receivers are compatible with the ULXD6/C (White)?
A: This transmitter is compatible with ULX-D receivers (ULXD4, ULXD4D, ULXD4Q) and QLX-D receivers. Frequency bands must match between transmitter and receiver when purchasing separately.

Q: Can this transmitter be used in a large facility with many simultaneous wireless microphones?
A: Yes. With Shure antenna distribution components, up to 200 ULXD6 transmitters can operate using a single pair of receiving antennas, supporting high-density multi-table wireless deployments at convention centers, government campuses, and large commercial facilities.

Q: Does this transmitter support network-based charging management?
A: Yes. The ULXD6/C is compatible with the SBC250 (2-bay), SBC450 (4-bay), and SBC850 (8-bay) Networked Charging Stations, enabling remote battery status monitoring and centralized charging management for multi-unit commercial deployments.
