Product Overview
The Shure QLXD2/KSM9HS is a QLD-D digital wireless handheld transmitter fitted with the premium KSM9HS condenser capsule, engineered for high-demand vocal applications in music venues, houses of worship, and commercial AV installations. The KSM9HS represents Shure's top-tier handheld condenser capsule offering in the QLXD wireless platform, combining the transparency of a studio-grade condenser with the 24-bit digital audio quality of the QLXD2 transmitter. With a 100-meter operating range and one-touch IR sync, this system is suited for integrators and system designers specifying premium wireless microphone solutions for permanent or touring deployments.
Product Description
The QLXD2/KSM9HS pairs the proven QLXD2 transmitter platform with Shure's KSM9HS capsule, a premium condenser designed to deliver detailed, high-fidelity vocal reproduction in demanding live and installed environments. The QLXD2's transparent 24-bit digital wireless transmission ensures the full character of the KSM9HS capsule is preserved without the noise floor or artifact limitations of analog wireless systems. One-touch IR sync with a paired QLXD4 receiver simplifies frequency coordination in multi-channel deployments, while the all-metal transmitter body provides the durability required for commercial-grade use. An optional SB900C rechargeable lithium-ion battery provides up to 10 hours of runtime. For a condenser alternative at a lower price point, see the Shure QLXD2/B87C.
