Shure QLXD2/B58 H51 Wireless Handheld Microphone Transmitter

Shure QLXD2/B58 Handheld Wireless Transmitter (H51 frequency band)

The Shure QLXD2/B58 is a professional digital handheld transmitter designed for use with Shure QLX-D® series wireless systems. This specific model comes with the legendary Beta 58A microphone capsule. The Beta 58A is a dynamic microphone with a supercardioid polar pattern, which ensures excellent rejection of off-axis noise and a high gain-before-feedback level, making it ideal for vocals during live performances.

The transmitter features transparent 24-bit digital audio transmission and efficient spectrum utilization. The QLXD2 has a robust, metal body, adapted for intensive stage use. One of its key features is AES-256 encryption, ensuring secure signal transmission, which is relevant for confidential events. The transmitter can be powered by two AA batteries or an optional Shure SB900A lithium-ion rechargeable battery, which displays the remaining operating time in minutes. This version operates in the H51 frequency range.
