Shure KSM42/SG Wired Condenser Microphone

The Shure KSM42/SG is a premium, side-address condenser microphone designed to elevate vocal recording and performance to world-class levels. Built around a large dual-diaphragm capsule, this microphone delivers a rich, musical voice with controlled proximity effects and a presence-rich top end that translates beautifully across genres—from polished studio vocal takes to dynamic live performances. Its thoughtful design combines meticulous internal and external pop filtering with a cardioid pattern to minimize ambient noise and stage spill, making it a versatile tool for studios, broadcast rooms, and performance venues alike. The harmonized blend of warmth, clarity, and resilience makes the KSM42/SG a trusted choice for engineers who demand a breathy, intimate vocal sound without sacrificing body or articulation.

• Dual-diaphragm capsule for expansive, warm vocal detail — The large dual-diaphragm design delivers a natural, open vocal tone with a balanced low end and controlled upper harmonics, capturing the nuance of breath, inflection, and articulation while maintaining a smooth, non-sibilant top end across voice types.
• Cardioid pattern with excellent off-axis rejection — Engineered to reduce room noise and feedback, the KSM42/SG keeps the vocal front-and-center even in lively rooms, allowing closer mic placement for intimacy without gobbling up unwanted reflections.
• Integrated pop filtering for clean plosive control — A comprehensive internal pop filter works in concert with the microphone’s design to minimize plosives, enabling close-mic technique for expressive vocal performances and broadcast-quality delivery.
• Tailored frequency response for vocal clarity — The response curve is crafted to emphasize presence and intelligibility while smoothing harsh sibilance, resulting in a vocal tone that sits well in dense mixes and sits comfortably in broadcast or podcast contexts.
• Rugged, road-ready construction — An all-metal chassis and robust internal components provide durability for studio sessions and on-stage use, ensuring reliable performance under demanding conditions and frequent transport.
