Shure ULXD6 C
The ULXD6/C is a wireless boundary microphone transmitter for Shure's ULX-D digital system, built for tabletop use at meetings and events where a wired microphone is impractical. Its low-profile boundary form factor sits flat on a conference or dais surface, and the cardioid element focuses pickup on the talker in front while rejecting off-axis room noise. Paired with a ULX-D or QLX-D digital receiver, it delivers transparent 24-bit/48 kHz audio with AES-256 encryption for secure, reliable coverage.
A configurable mute button supports Toggle, Push-to-Mute, Push-to-Talk, or disabled behavior, with matching Mute LED options, so it adapts to boardroom and worship workflows alike. Selectable 1/10/20 mW RF output lets you trade range for channel count, and the transmitter reaches up to 300 feet line of sight. It runs up to 8 hours and 40 minutes on two AA batteries, or an optional lithium-ion rechargeable pack provides up to 9 hours.
