The Shure QLXD2 SM87 G51 is a wireless handheld microphone designed to meet the rigorous demands of stage professionals, whether for concerts, corporate seminars or outdoor events. Transmitting on the G51 carrier frequency band (470 to 534 MHz), it ensures optimal audio quality and secure RF transmission thanks to 256-bit AES encryption, with a range of up to 100 meters.

Powered by the Shure SB900A rechargeable lithium-ion battery (sold separately), the QLXD2 lasts up to 10 hours of continuous battery life, and can also run on standard LR6 batteries for approximately 9 hours. Recharging is facilitated by the SBC200 or SBC220 double chargers via the external contacts of the microphone for convenient handling.

Advanced Shure Gain Ranging technology automatically adjusts gain based on the audio source, removing the need for manual adjustments and optimizing the signal-to-noise ratio. With its two audio paths, it achieves a dynamic range of over 120 dB which ensures balanced and optimal signal transmission to the receiver.

Built with a sturdy cast aluminum housing, the QLXD2 SM87 G51 is ideally suited to heavy-duty, regular use. Its frequency and power lock feature ensures parameter stability, while the backlit LCD screen simplifies navigation and control for an intuitive user experience.

Thanks to its integrated Shure SM87 capsule, this microphone provides a very precise supercardioid polar pattern, ideal for rejecting unwanted noise during performances on stage with personal monitors or in difficult acoustic environments. The three-point silentblock mount minimizes handling noise, while the anti-pop filter reduces wind and breathing noise, ensuring clear and precise capture.
