Overview
The Shure QLXD14/85 rackmount digital wireless lavalier microphone system provides instructors, presenters, and broadcasters with professional-quality audio, reliable RF performance, and secure AES 256-bit encryption. Rugged and easy-to-use, it is ideal for use in TV broadcast or sound-reinforcement applications in medium-sized venues and houses of worship, as well as A/V installations in conference, educational, and corporate facilities.
The QLXD14/85 operates in the UHF band to transmit pristine 24-bit/48 kHz digital audio with clarity, accurate low end, and crisp transient response. It utilizes Digital Predictive Switching Diversity to protect the transmission from interference and deliver solid RF signal stability without audio artifacts. You can run up to 60 mic channels at the same location.
The system comes with a WL185 cardioid lavalier microphone optimized for speech intelligibility. The bodypack transmitter provides up to 9 hours of operation on two AA batteries, with selectable 1/10mW RF power and a transmission range up to 330'.
- Includes QLXD4 digital wireless receiver, QLXD1 wireless bodypack transmitter, & WL185 lavalier mic
- Transparent 24-bit digital audio captures every performance detail
- Over 120dB of dynamic range eliminates transmitter gain adjustment
- Wide 64 MHz tuning bandwidth (region dependent)
- Up to 17 compatible systems per 6 MHz TV channel
