Performance CHARACTERISTICS

The KSM313, like all ribbon microphones, performs 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. We recommend using preamps with impedance settings of 1000 Ohms or more.

The KSM313 is a low-noise microphone. The combination of its efficient transducer, robust shielding, and custom transformer give the microphone a low noise floor and output level equal to moving coil microphones. Certain ribbon designs have weaker magnets and less shielding, and require additional gain for optimum perfor- mance. This is not the case with the KSM313. Most professional level preamplifiers with normal gain and high input impedance are well suited for this microphone.

The KSM313 is quite natural sounding and does not require color- ation at the preamp stage for optimal performance. Preamps that provide simple, transparent gain usually provide the best results.

However, you may prefer a more colored sound, and we encourage you to experiment to find the right combination that suits your taste.

When addressing the rear side of the KSM313 please remember to invert the signal polarity.*

ksm313 specifications

The Shure KSM313 is a premium ribbon microphone renowned for its exceptional sound quality and versatility in a variety of recording environments. Designed for professional use, the KSM313 stands out with its innovative technology and features that cater to both studio and live performance applications.

One of the defining characteristics of the KSM313 is its dual-element ribbon design, which provides a warm and natural sound reproduction. This design incorporates two distinct ribbon elements, each tuned to capture different frequency ranges, resulting in an extended frequency response that allows for rich lows and smooth highs. This makes the KSM313 particularly effective for capturing vocals, guitars, and various acoustic instruments, ensuring every nuance is preserved.

The KSM313 also features a unique bi-directional polar pattern, which captures sound equally from the front and rear while rejecting noise from the sides. This characteristic is particularly advantageous in ensemble settings or when recording in untreated rooms, as it helps isolate the sound source, minimizing bleed from other instruments or environmental noise.

The build quality of the KSM313 is robust, featuring a durable metal chassis that can withstand the rigors of professional use. The ribbon is designed to be resilient, with an innovative protection system that guards against loud sound levels, making the microphone suitable for high-output sources like guitar amplifiers and brass instruments.

Additionally, the KSM313 incorporates advanced technologies such as a patented ribbon design that enhances the microphone's sensitivity and transient response. This is crucial for capturing the detailed dynamics of a performance, allowing audio engineers to achieve studio-quality recordings with ease.

In terms of connectivity, the KSM313 is equipped with a standard XLR output, making it compatible with most audio interfaces and mixing consoles. With a frequency response range of 30 Hz to 20 kHz, it covers the full spectrum of audio, ensuring that it accurately captures the richness and depth of sound.

In summary, the Shure KSM313 ribbon microphone combines cutting-edge technology with rugged construction to deliver exceptional performance in a variety of recording situations. Its warm sound profile, effective polar pattern, and durable design make it a top choice for professionals seeking to achieve the highest audio fidelity. Whether used in a studio or live setting, the KSM313 is a reliable tool that artists and engineers can depend on for outstanding results.
