Shure ULXD2/K8B=-G57
Product Overview
The Shure ULXD2/K8B is a digital handheld wireless transmitter built around the KSM8 Dualdyne dynamic capsule, designed for commercial AV installation projects that want premium vocal capture with the RF performance and encryption of the ULX-D platform. This ULX-D digital wireless handheld transmitter delivers AES 256-bit encryption and a 330-foot operating range, giving AV integrators a secure handheld option for auditoriums, government facilities, and performance spaces specifying a premium dynamic capsule.
Product Description
The ULXD2/K8B pairs Shure's ULX-D digital wireless platform with the KSM8 capsule, a dual-diaphragm dynamic microphone using Shure's Dualdyne technology to reduce proximity effect and minimize off-axis coloration compared to a traditional single-diaphragm dynamic capsule. The transmitter delivers 24-bit/48kHz digital audio with a 20 Hz to 20 kHz frequency response (±1 dB) and greater than 120 dB of A-weighted dynamic range.
Selectable RF power of 1, 10, or 20 mW lets integrators balance battery life against range and interference rejection, and image rejection greater than 70 dB helps maintain a clean RF signal in dense wireless environments. AES 256-bit encryption protects transmitted audio for confidential meetings or security-sensitive AV integration projects, and the transmitter's cast aluminum housing is built for durable daily use. Battery runtime is rated at under 12 hours at 10 mW using a Shure SB900A rechargeable battery.
