Shure KSM40C Large-Diaphragm Cardioid Condenser Microphone

The Shure KSM40C is a large-diaphragm cardioid condenser microphone designed for recording professionals who require accurate, true-to-life sound with pristine low-noise performance for capturing vocals and instruments. Part of the refreshed KSM Studio Microphone line from Shure, the KSM40C combines refined capsule engineering, updated electronics, and premium accessories in a sleek, modern design built for contemporary studio workflows.

The uniform cardioid polar pattern focuses tightly on the source while minimizing room sound and bleed, making placement fast and predictable in multi-microphone sessions or less-than-ideal spaces. A smooth proximity effect provides additional creative flexibility, allowing engineers to move closer for a larger-than-life sound or pull back for a more neutral, transparent capture.

Extremely low self-noise supports clean recordings with greater headroom, enabling gain and compression without unwanted hiss. The lightweight, all-metal construction ensures durability while keeping the microphone easy to position on boom stands. A precision-machined steel grille highlights the gold-layered capsule and reinforces long-term reliability for daily professional use.

The KSM40C includes a proprietary shockmount that isolates the microphone from rumbles and vibrations, along with a detachable magnetic pop filter to reduce plosive sounds. A premium zippered carrying case, threaded adapter, and an extra set of shockmount bands complete the accessory suite, delivering a studio-ready microphone system designed for critical vocal and instrument recording.
