Shure KSM313 Dual-Voice Ribbon Microphone

Overview

The Shure KSM313/NE is a ribbon microphone designed to deliver two distinct sonic characters in a single bi-directional package, making it a versatile tool for both studio recordings and live performances. It features a frequency response from 30 Hz to 15 kHz and can handle sound pressure levels up to 146 dB without distortion, allowing it to capture a wide range of sources with clarity and warmth.

Key features

• Dual voice motor offers a bright side for vocals that need presence and clarity, and a warm side that adds body to instruments like guitar cabinets and brass sections
• Bi-directional polar pattern reduces off-axis sound, improving isolation and minimizing room reflections and bleed
• Roswellite ribbon material resists stretching or deformation even at very high sound pressure levels, ensuring durability and consistent performance
• Passive operation with a standard three-pin XLR connection eliminates the need for external power, simplifying setup and compatibility
• Hand assembled in the United States using machined steel, aluminum, and precious metal components for ruggedness and reliability in demanding environments

Performance and reliability

The KSM313/NE’s advanced Roswellite ribbon material allows it to withstand extremely high sound pressure levels without damage, making it suitable for close-miking loud sources such as guitar amps and drums. Its robust construction with machined steel and aluminum parts ensures it can endure the rigors of touring and frequent studio use. The microphone’s bi-directional pattern helps maintain focus on the intended sound source by rejecting unwanted ambient noise and reflections.

Ideal uses and environments

This microphone is well suited to engineers and performers who require quick tonal flexibility during sessions or live shows. The ability to switch between a bright vocal tone and a warm instrumental tone by simply flipping the mic makes it a strong choice for vocalists, guitarists, brass players, and other musicians. It fits naturally into professional studio setups and live sound environments where isolation and tonal control are important.
