Shure KSM353/ED | Premier Bi Directional Ribbon Microphone

The Shure KSM353/ED is a top-tier, bi-directional ribbon microphone designed specifically for capturing pristine audio in studio and concert hall settings. This exceptional microphone features proprietary Roswellite technology, which offers unmatched ribbon resilience and durability even under the most extreme conditions. Hand-assembled in the USA using state-of-the-art transducers, transformers, and metals, the KSM353/ED represents the pinnacle of Shure quality, making it the microphone of choice for elite vocal and acoustic performances. Whether you're recording delicate acoustics in a studio or powerful vocals on stage, the KSM353/ED ensures superior audio fidelity and performance.

The revolutionary design of the Roswellite ribbon material surpasses traditional foil ribbons, providing high-tensile strength, toughness, and shape memory. This ensures the microphone performs exceptionally well at extreme sound pressure levels (SPLs), making it ideal for both quiet and loud environments. The double-shielded, full-sized transformer minimizes signal loss and maximizes output, while reducing magnetic and RF interference. Additionally, the bi-directional polar pattern offers symmetrical audio capture with superior off-axis rejection, ensuring that only the intended sounds are recorded with clarity and precision.

Overall, the Shure KSM353/ED embodies legendary Shure quality and superior construction. It incorporates advanced technology and high-quality materials such as machined steel, silver, gold, and aluminum, all housed in a pure stainless steel casing. When it comes to capturing fast transients, rich low and mid ranges, and superior upper range presence, the KSM353/ED stands as a necessary tool for the world’s most accomplished studio and live performances.
