Description
The Shure ULXD2/KSM9HS is a premium digital handheld wireless transmitter engineered for professional live sound, broadcast, and installed audio environments. Designed for seamless integration with ULX-D digital wireless systems, this transmitter delivers pristine 24-bit/48 kHz audio with exceptional clarity, low latency, and reliable RF performance across demanding applications.
Equipped with the advanced KSM9HS dual-diaphragm condenser capsule, the ULXD2/KSM9HS provides unmatched vocal detail and flexibility. With switchable hypercardioid and subcardioid polar patterns, audio engineers can optimize performance for both high-volume stages and more open acoustic environments. The hypercardioid mode enhances off-axis rejection and gain before feedback, while the subcardioid setting delivers natural tonal balance with broader coverage.
Built with a rugged yet lightweight aluminum housing, the transmitter is designed for durability without compromising handling comfort. Shure’s proprietary Gain Ranging automatically adjusts input levels, eliminating the need for manual gain tuning and ensuring consistent audio output. AES-256 encryption guarantees secure transmission, making it ideal for corporate, government, and high-security applications.
User-friendly controls, including a backlit LCD, IR sync, and lockable settings, provide quick setup and reliable operation. Flexible power options support both standard AA batteries and Shure SB900A rechargeable systems with intelligent battery monitoring and extended runtime, making it a dependable solution for long performances and critical events.
