Shure QLXD2/KSM8 Digital Handheld Wireless Microphone Transmitter

The Shure QLXD2/K8B=-J50A is a handheld wireless microphone transmitter designed for stages, conference rooms, and worship spaces where dependable audio and easy setup matter. It pairs seamlessly with any Shure QLX-D receiver, giving performers and technicians a straightforward way to build a secure digital wireless system.

At the heart of the transmitter sits Shure’s KSM8 dual-diaphragm dynamic capsule. This design captures vocals with natural detail and keeps the proximity effect under control, so the sound stays balanced whether the mic is right on a singer’s lips or moving around a podium. The 24 bit digital signal path preserves those nuances from capsule to receiver without audible noise or compression artifacts.

Operating in the 572 to 616 MHz band, the transmitter maintains a working range of up to 100 meters, plenty for large stages or multi-room venues. AES 256 bit encryption is built in, protecting every channel from prying ears during corporate events, broadcast shoots, or sensitive presentations. One touch infrared sync locks frequencies in seconds, so changeovers between acts stay smooth.

Two standard AA batteries power the unit for as long as nine hours, and anyone looking for a rechargeable option can drop in the optional Shure SB900B pack for even longer runtimes and easy charging. The metal body is made for rugged use, shrugging off the bumps that come with touring and busy production schedules.
