The Shure QLXD2/SM87 is a premium digital wireless handheld system that pairs the advanced QLXD wireless platform with the SM87 cardioid condenser microphone capsule. This system is engineered for vocalists and presenters who require detailed, natural sound reproduction with superior feedback rejection in live sound applications. The QLXD2 handheld transmitter features a rugged metal body, a high-resolution color display for clear status monitoring, and operates on a digital UHF link that delivers 24-bit audio quality with a wide dynamic range and ultra-low latency. This ensures the vocalist's performance is transmitted with exceptional clarity and precise timing.

The SM87 capsule is a cardioid condenser microphone known for its smooth, flat frequency response and excellent off-axis rejection. Its design provides a natural vocal tone with enhanced presence that helps vocals sit clearly in the mix without harshness. The condenser element captures finer details and transients compared to dynamic microphones, resulting in a more open and articulate sound. The capsule includes an effective internal pop filter and shock mount to minimize plosives and handling noise. When integrated with the QLXD2 transmitter, it offers the freedom of wireless movement without compromising the sonic integrity expected from a high-quality condenser microphone, making it ideal for lead vocals, broadcast, and demanding presentation environments.

This system represents a significant step up in wireless vocal quality, offering the transparency and detail of a studio condenser in a reliable wireless format. It is particularly well-suited for vocalists who prefer a more natural, less colored sound and for applications where audio fidelity is paramount. The combination of the QLXD platform's networking capabilities and the SM87's refined acoustic performance makes it a powerful tool for professional live sound reinforcement.
