Shure ULXD6/O Digital Wireless Omni Boundary Microphone Transmitter (Black, J50A: 572 to 608 + 614 to 616 MHz) - ULXD6/O=-J50A

Product Overview

The Shure ULXD6/O is a professional digital wireless omnidirectional boundary microphone transmitter designed for tabletop conference room, boardroom, and large meeting venue applications where wired microphones are impractical. With a low-profile boundary form factor, very low system latency for live sound reinforcement, and long transmission range up to 300 feet (100 meters), it integrates with ULX-D and QLX-D digital receiver systems to deliver consistent, intelligible audio capture across meeting tables and conference surfaces. This listing covers the black version in the J50A frequency band (572–608 + 614–616 MHz).

Product Description

The ULXD6/O omnidirectional boundary microphone transmitter provides 360-degree pickup from its low-profile tabletop form factor, capturing all participants around a conference table without directional placement requirements. Very low system latency makes it appropriate for meetings requiring simultaneous live sound reinforcement alongside wireless transmission. The system supports up to 200 ULXD6 transmitters sharing a single pair of receiving antennas when used with Shure antenna distribution components, enabling large-scale multi-table deployments in convention centers and government facilities without proportional antenna infrastructure costs. The configurable mute button supports Toggle, Push-to-Mute, Push-to-Talk, or disabled operation to accommodate different meeting workflow requirements. Optional SBC250, SBC450, and SBC850 networked charging stations support fleet management across multi-transmitter installations.

Key Features

• Omnidirectional Boundary Microphone Capsule — Provides 360-degree pickup from a flat tabletop surface, capturing all meeting participants without directional placement or per-seat microphone positioning.
• Very Low System Latency — Enables live sound reinforcement simultaneous with wireless transmission, essential for large conference and convention center meeting rooms requiring PA support.
• Long Transmission Range (Up to 300 ft / 100 m) — Delivers reliable wireless audio performance in very large meeting venues, conference centers, and government facilities.
• Up to 200 Transmitters Per Antenna Pair — Supports massive multi-transmitter deployments at convention centers and large facilities using a single pair of Shure antennas and distribution components.
• Configurable Mute Button — Supports Toggle, Push-to-Mute, Push-to-Talk, or disabled configurations to match specific meeting workflow and participant control requirements.
• 12-Hour Rechargeable Battery — Optional SB900C rechargeable lithium-ion battery provides up to 12 hours of runtime; also compatible with standard AA alkaline batteries for immediate replacement in the field.
• Networked Charging Station Compatibility — Compatible with SBC250, SBC450, and SBC850 networked docking stations for streamlined fleet charging and monitoring across multi-transmitter deployments.
• ULX-D and QLX-D Receiver Compatibility — Integrates with ULXD4, ULXD4D, and ULXD4Q receivers as well as QLX-D systems; frequency bands must match.

Frequently Asked Questions

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

Q: What receivers are compatible with the ULXD6/O?
A: The ULXD6/O=-J50A is compatible with ULX-D receivers (ULXD4, ULXD4D, ULXD4Q) and QLX-D receivers operating in the J50A frequency band. Frequency bands must match between transmitter and receiver.

Q: How many ULXD6 transmitters can operate simultaneously in a large conference facility?
A: With Shure antenna distribution components, up to 200 ULXD6 boundary transmitters can operate using a single pair of receiving antennas, enabling large-scale multi-table wireless deployments at convention centers, government facilities, and corporate campuses.

Q: Can this transmitter be used with networked charging stations for fleet management?
A: Yes. The ULXD6 is compatible with the SBC250 (2-bay), SBC450 (4-bay), and SBC850 (8-bay) Networked Charging Stations, which support remote battery monitoring and charging management across multi-transmitter installations.
