Shure ULXD6W/O – Digital Wireless Omni Boundary Mic Transmitter, White (G50)

Product Overview

The Shure ULXD6W/O is a digital wireless omnidirectional boundary microphone transmitter designed for tabletop use in conference rooms, boardrooms, government spaces, and commercial meeting environments. Operating in the G50 band (470–534 MHz), it integrates with ULX-D and QLX-D digital wireless receivers to deliver 24-bit/48 kHz digital audio with a flat 20 Hz–20 kHz frequency response. The white finish ensures a discreet, professional appearance on conference tables and presentation surfaces where aesthetics matter in commercial AV deployments.

Product Description

The Shure ULXD6W/O digital wireless boundary mic transmitter captures omnidirectional audio from meeting participants without requiring a visible microphone stand, maintaining a clean table surface. The configurable mute button supports Toggle, Push-to-Mute, Push-to-Talk, or fully disabled modes to match the workflow requirements of the facility or integrator. Adjustable RF transmitter power (1, 10, 20 mW) allows optimization for room size and spectrum congestion. A selectable high-pass filter helps manage HVAC noise and low-frequency room rumble common in commercial spaces. Compatible with ULX-D receivers such as the Shure ULXD4Q Quad-Channel Receiver. For the cardioid boundary transmitter variant, see the Shure ULXD6/C Boundary Mic Transmitter.

Key Features

• 24-Bit/48 kHz Digital Audio — Delivers broadcast-quality digital audio with a flat 20 Hz–20 kHz frequency response and greater than 120 dB dynamic range for clear, intelligible conference and presentation audio.
• Omnidirectional Polar Pattern — Captures audio from all directions around the tabletop, making it well-suited for round-table conference room deployments where participants are distributed around the microphone.
• Configurable Mute Button — Supports Toggle, Push-to-Mute, Push-to-Talk, and disabled modes to match the specific operational requirements of the facility or AV system design.
• Adjustable RF Transmitter Power — Selectable 1, 10, and 20 mW output allows the integrator to optimize coverage for room size while minimizing RF interference in multi-channel installations.
• High-Pass Filter — Selectable filter reduces low-frequency noise from HVAC systems, projector fans, and other commercial building infrastructure.
• White Finish — Discreet commercial-grade finish blends with white conference tables and light-colored meeting room furniture for professional aesthetics.
• Low-Profile Boundary Form Factor — Flat tabletop design requires no stand or mounting hardware, enabling rapid deployment and clean table surface presentation in commercial meeting spaces.
• ULX-D and QLX-D Compatible — Integrates with Shure's professional digital wireless receiver ecosystem for consistent RF and audio performance across multi-channel installations.

Frequently Asked Questions

What receivers are compatible with the ULXD6W/O G50?
The ULXD6W/O G50 is compatible with ULX-D receivers (ULXD4, ULXD4D, ULXD4Q) and QLX-D receivers in the G50 band. All components must match the same frequency band for proper operation.

How many ULXD6W/O transmitters can run simultaneously?
ULX-D supports up to 22 simultaneous channels in a standard 8 MHz TV channel, and up to 47 in High Density mode (depending on receiver model). Actual channel count depends on RF environment and proper frequency coordination.

Can the mute LED be configured for confidentiality?
Yes. The mute LED behavior is configurable alongside the mute button function, allowing integrators to disable the visible indicator for applications where LED visibility is undesirable.

What is the battery solution for the ULXD6W/O?
The ULXD6W/O supports optional SB900C rechargeable batteries providing up to 12 hours of run time. Standard AA batteries can also be used.

Is the ULXD6W/O suitable for permanent installation?
Yes. The low-profile form factor and configurable RF power make it well-suited for permanent conference room and boardroom installations integrated with ULX-D rack-mounted receiver systems.
