Description The KSM353/ED is a premium 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. Assembled 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 unique 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 The KSM353/ED from Shure is a superior ribbon microphone designed for high-quality reproduction in the studio or concert hall. The mic is hand-assembled in the United States, and features the build quality that Shure mics are renowned for. Shure outfitted the KSM353/ED with its proprietary Roswellite ribbon material, which has more strength and resilience than a conventional foil ribbon. The mic is also equipped with a custom ribbon-motor assembly, which helps tailor bass response and improve presence. A custom-wound double-shielded, full-size transformer keeps signal loss at a minimum and increases output. The KSM353/ED’s bi-directional polar pattern delivers totally symmetrical audio and superior off-axis rejection. Shure recommends using mic preamps with impedances of at least 1 kOhm to get optimal low-end and midrange performance. The mic offers a low noise floor, and an output level that’s on par with moving-coil microphones. Bi-directional polar pattern delivers premier, completely symmetrical audio with superior off-axis rejection Revolutionary Roswellite proprietary ribbon material replaces traditional foil ribbons with high-tensile strength, toughness, and shape memory that provides superior resilience at extreme SPLs Patented 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 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 146 dB SPL across 30 – 15,000 Hz frequency response ideal for capturing fast transients in vocals, acoustic instruments, and concert halls 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 Specifications Key Specs Element Type Ribbon Polar Pattern Figure-8 Frequency Range 30 Hz to 15 kHz Maximum SPL 146 dB SPL Analog Output 1x XLR 3-Pin Microphone Element Type Ribbon Polar Pattern Figure-8 Performance Frequency Range 30 Hz to 15 kHz Maximum SPL 146 dB SPL Impedance 330 Ohms Sensitivity 2.11 mV/Pa Connectivity Analog Output 1x XLR 3-Pin Physical Dimensions ø: 1.9 x L: 6.2″ / ø: 48.26 x L: 157.48 mm Weight 1.4 lb / 635.03 g
