Shure - KSM353/ED Premium Bi-directional Ribbon Microphone

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
• 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

Performance Characteristics
Ribbon microphones perform optimally with the least amount of loading on the ribbon element as practical. The higher the impedance input on the microphone, the better the low-end and mid-range frequencies are represented in the output signal. Shure recommends using preamps with impedance settings of 1000 Ohms or more, although different load impedances may be used for a desired sound quality.

This is a low-noise microphone. The combination of its efficient transducer, robust shielding, and custom transformer produces a low noise floor and output level equal to moving coil microphones.

Shure ribbon microphones have an exceptionally smooth, natural response and perform best with preamps that provide simple, transparent gain. However, Shure encourages experimentation to find the desired combination of colour and transparency.

Applications
The KSM353 is a premium microphone, capturing superior audio quality in a wide range of environments. The following are some suggested applications:
• Studio vocals
• Orchestra ensembles
• Acoustic instruments
• Ambient or room pickup
• Voice-over for film or broadcast
