General Description

The KSM313 is a premium bidirectional ribbon microphone for world-class audio recording and

performance. The "Dual-Voice" design features discrete front and rear sonic signatures to accurately

capture intimate vocals or intricate instrumentation.

The KSM313 is hand-assembled in the U.S.A. from state-of-the-art transducers, transformers and

metals as the pinnacle of Shure quality. The revolutionary Roswellite

traditional foil ribbons with high tensile strength, toughness and shape-memory, providing superior

resilience at extreme sound pressure levels (SPLs).

Features

• Legendary Shure quality and superior construction from hand-assembly of machined steel, silver,

gold and aluminum components

• Revolutionary Roswellite ribbon material replaces traditional foil ribbons with high tensile

strength, toughness and shape-memory, providing superior resilience at extreme SPLs

• True "Dual-Voice" ribbon motor assembly, tuned specifically for user's choice of frequency

response: address the front for warm and full sounding amplifiers, or swivel around for bright and

flattering vocals and acoustic instruments

• 30–15,000 Hz frequency response ideal for capturing vocals, acoustic and amplified instruments

• Uniform bidirectional polar pattern throughout the frequency range

• Custom-wound, double-shielded, full-size transformer minimizes signal loss and RF interference,

and maximizes output

• Improved hard stand mount for flexible, discreet mic placement

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 imped-

ance 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 color and transparency.
