Description
The Shure ULXD2/KSM9 is a premium VHF digital handheld wireless microphone transmitter engineered for professional live sound environments where clarity, control, and reliability are essential. Designed for seamless integration with ULX-D receivers, this transmitter features the acclaimed KSM9 condenser capsule, delivering studio-quality vocal reproduction with exceptional detail and accuracy.
Equipped with dual switchable polar patterns, the KSM9 capsule allows audio engineers to adapt quickly to different stage conditions. Cardioid mode provides a warm, natural tone with strong feedback rejection, while supercardioid mode enhances isolation in high-noise environments or multi-performer setups.
The ULXD2/KSM9 ensures pristine 24-bit/48 kHz digital audio transmission with low latency and secure AES-256 encryption, making it ideal for high-profile events, corporate presentations, houses of worship, and live performances. Its rugged yet lightweight aluminum construction ensures durability without compromising comfort during extended use.
Advanced features such as automatic gain adjustment, infrared synchronization, and selectable RF output power streamline setup and operation. Flexible power options, including AA batteries or the optional Shure SB900A rechargeable battery, provide reliable performance with extended runtime and intelligent power monitoring capabilities.
