FAQ

What is Roswellite Ribbon Technology in the Shure KSM353 Microphone?

Roswellite Ribbon Technology is a proprietary feature of the Shure KSM353 Microphone. It is a revolutionary material that provides superior ribbon resilience and durability, even under extreme conditions. This high-tensile strength and toughness surpass traditional foil ribbons, ensuring top-notch performance at high Sound Pressure Levels (SPLs).

What does 'bi-directional' mean in the context of the Shure KSM353 Microphone?

A 'bi-directional' microphone, like the Shure KSM353, is designed to pick up sound from two opposite directions - front and back. This is achieved through its figure-8 polar pattern. This design makes it an ideal choice for recording vocals and acoustic performances where sound is coming from multiple directions.

The Shure KSM353 Microphone is a professional-grade, high-quality audio device. It is hand-assembled in the USA and is part of Shure's esteemed KSM series. It features innovative Roswellite Ribbon Technology and a bi-directional figure-8 polar pattern. These features, combined with state-of-the-art transducers and transformers, set it apart from other microphones on the market.

Is the Shure KSM353 Microphone suitable for live performances?

Yes, the Shure KSM353 Microphone is not only suitable but an excellent choice for live performances. Its bi-directional figure-8 polar pattern and Roswellite Ribbon Technology make it capable of capturing high-quality sound in various settings, including concert halls.
