Shure KSM353/ED Premier Bi-Directional Ribbon Microphone with Roswellite Ribbon Technology

The Shure KSM353/ED is a premier bi-directional ribbon microphone designed for pristine audio capture in studio and concert hall applications. Featuring Shure's proprietary Roswellite® ribbon technology, this microphone offers exceptional durability and resilience under extreme sound pressure levels (SPLs), making it ideal for capturing fast transients in vocals, acoustic instruments, and live performances. Its bi-directional polar pattern delivers symmetrical audio with superior off-axis rejection, ensuring clear and focused recordings.

Hand-assembled in the USA, the KSM353/ED combines high-quality materials, including machined steel, silver, gold, and aluminum, housed in a pure stainless steel casing. The microphone's custom ribbon motor assembly tailors bass response without attenuating overall output, providing full low and mid ranges and superior upper range presence. Additionally, the double-shielded matched full-sized transformer minimizes signal loss and reduces magnetic and RF interference, ensuring optimal performance in various environments.
