The KSM353 is a first-class bi-directional ribbon microphone crafted for pristine audio in studio and concert hall applications. Proprietary Roswellite technology provides revolutionary ribbon resilience and durability under extreme conditions.

 

Hand assembled in the USA from state-of-the art transducers, transformers and metals as the pinnacle of Shure quality for prestigious vocal and acoustic performances. The high-tensile strength, toughness and shape memory of Roswellite™ ribbon material replaces traditional foil ribbons for superior resilience at extreme SPLs.

 

With advanced technology and application features, alongside superior materials and construction, Shure KSM Ribbon Microphones are the necessary choice for the world’s most accomplished studio and live performances.

 

Features:

Revolutionary Roswellite proprietary ribbon material replaces traditional foil ribbons with high tensile strength, toughness and shape memory that provides superior resilience at extreme SPLs

Bi-directional polar pattern delivers premier, completely symmetrical audio with superior off-axis rejection

Double-shielded  matched full-sized transformer minimizes signal loss and maximizes output while reducing magnetic and RF interference from 90 degree placement, offset relative to the ribbon

Custom ribbon motor assembly tailors bass response without attenuating the overall output for full low and mid ranges, and superior upper range presence from a rising frequency response

Legendary Shure quality and superior construction from hand-assembly of machined steel, silver, gold and aluminum materials, and housed in a pure stainless steel casing

146dB SPL  across 30 – 15,000 Hz frequency response ideal for capturing fast transients in vocals, acoustic instruments and concert halls

Spring-loaded suspension shock mount for flexible, fully-isolated stand mounting.

Upright protective wood case included for storage when not in use
