Shure QLXD14/85 Digital Wireless Cardioid Lavalier Microphone System

The Shure QLXD14/85-X52 is a wireless lavalier microphone system that delivers 24 bit digital audio over the UHF band for spoken-word applications. It brings together the WL185 cardioid lavalier microphone, a bodypack transmitter, and a half-rack receiver to give presenters and performers clear, consistent sound without being tied to a podium or cable.

The included WL185 mic captures speech with a cardioid pickup pattern that focuses on the voice in front of it while reducing room noise coming from the sides. This makes it a practical choice for corporate meetings, classroom lectures, worship services, and on-camera interviews where intelligibility matters more than anything else.

Audio is transmitted with minimal latency, so voices stay in sync with video feeds during live streams or recordings. Operating in the UHF spectrum and using Digital Predictive Switching Diversity, the system maintains a clean signal at distances up to 330 feet when line of sight is available. Users can move across a stage, down an aisle, or around a set without worrying about sudden dropouts.

The bodypack transmitter runs up to nine hours on two AA batteries, enough for a full workday or multiple back-to-back sessions. Meanwhile, the receiver’s backlit LCD lets technicians check levels, frequencies, and battery status even in low-light control booths. One-touch infrared sync pairs the transmitter and receiver in seconds, and the built-in Ethernet port allows networked monitoring and frequency coordination when several channels are in play.

For situations that demand confidentiality—board meetings, corporate keynotes, or broadcast productions—the system supports AES 256 bit encryption. This keeps private conversations from being intercepted over the air, giving users peace of mind in sensitive environments.
