Description
Featuring transparent 24-bit digital audio quality and incredibly efficient RF spectrum usage, the QLXD2 handheld transmitter is ideal for wireless vocals in presentation spaces, music venues, and houses of worship. Easy to use, the QLXD2 quickly syncs with a wireless receiver over IR at the push of a button and maintains clear, uninterrupted signal over its entire 100 m (330 ft.) range. All metal construction ensures durability, and a wide selection of compatible microphone choices offer legendary Shure sound signatures.
Features
The Shure QLXD2/KSM9 is a digital handheld wireless microphone transmitter compatible with QLX-D receivers. It comes equipped with a dual-diaphragm KSM9 condenser capsule that captures sonic nuances with superior detail, delivering precise vocal reproduction for high-end live performance. The KSM9 capsule offers two switchable polar patterns to provide FOH engineers with more choices in dealing with varying environments or the microphone techniques of different performers. The cardioid pattern offers solid gain before feedback, with minimal off-axis coloration, for a warm, full sound. The supercardioid pattern offers increased sound isolation and gain before feedback, an ideal choice for applications where there are high levels of ambient noise, or where multiple instruments or vocalists are close together.
The QLXD2/KSM9 operates on a 26 MHz UHF tuning range with 1040 selectable frequencies available. It provides up to 9 hours of operation on two AA batteries, with a transmission range up to 330′ and a selectable 1/10mW RF power output.
With a rugged, yet lightweight aluminum housing, the QLXD2/KSM9 transmitter delivers pristine audio quality and RF performance, as well as AES 256-bit encryption for secure transmission and advanced rechargeability options. It is well suited for sound reinforcement applications in medium-sized venues and houses of worship as well as A/V installations in conference, educational, and corporate facilities.
Clear, Accurate Audio with Interchangeable Capsule
- The unit delivers clear, reliable 24-bit/48 kHz digital audio.
- The KSM9 capsule with dual 3/4” gold-layered, low-mass Mylar diaphragms provides a consistent frequency response.
- The mic features Class-A, discrete transformerless preamplifier for transparency, extremely fast transient response, and no crossover distortion.
- The integrated three-stage “pop” protection grille reduces plosives, wind, and other breath noise.
- The interchangeable capsule design allows you to replace the KSM9 capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including SM58, SM87A, Beta 58A, Beta 87C, KSM8 capsules, and more.
