The ULXD6 Boundary Microphone Transmitter offers a low-profile boundary form factor that is ideal for meetings and events where quick setup and teardown is important or flexible seating arrangements make wired microphones impractical. With long transmission range (up to 300 feet/91 meters), the ULXD6 delivers reliable performance even when used in very large meetings at conference and convention centers.

Compatibility with the full line of Shure antennas and distribution components means that up to 200 ULXD6 boundary microphone transmitters can be used with just one pair of receiving antennas for efficient setup when time is short. The optional SB900A rechargeable batteries and SBC450 and SBC850 networked charging stations provide up to 9 hours of runtime and convenient charging when not in use. Standard AA alkaline batteries provide an additional power option.
