Shure QLXD2/KSM9HS Digital Handheld Wireless Microphone Transmitter

Exceptional Sound Quality with Dual-Diaphragm Capsule

The Shure QLXD2/KSM9HS is a high-performance digital handheld wireless microphone transmitter designed for use with QLX-D receivers. Featuring the advanced dual-diaphragm KSM9HS condenser capsule, it excels in capturing sonic nuances with unparalleled detail, making it ideal for high-end live performances.

Versatile Polar Pattern Options

The KSM9HS capsule offers two switchable polar patterns, providing front-of-house (FOH) engineers with versatile options to suit different environments and performers' techniques. The hypercardioid pattern delivers excellent off-axis rejection and extended gain before feedback, perfect for loud environments. The subcardioid pattern, on the other hand, offers a wide coverage angle with subtle off-axis rejection, resulting in a natural sound and reduced proximity effect.

Operating within a 44 MHz UHF tuning range and offering 1760 selectable frequencies, the QLXD2/KSM9HS ensures reliable performance with minimal interference. It provides up to 9 hours of operation on two AA batteries, with a transmission range of up to 330 feet, and selectable RF power output of 1/10 mW, making it adaptable for various venue sizes and applications.

Durable and Secure Design

Constructed from rugged yet lightweight aluminum, the QLXD2/KSM9HS transmitter is built for durability while maintaining pristine audio quality and RF performance. It includes AES 256-bit encryption for secure transmission and offers advanced rechargeability options, making it suitable for medium-sized venues, houses of worship, and A/V installations in conferences, educational, and corporate settings.
