KSM109 specifications

The Shure KSM109 is a remarkable small-diaphragm condenser microphone designed to deliver exceptional audio quality for a wide range of professional applications. Renowned for its accuracy and versatility, the KSM109 is favored by musicians, sound engineers, and recording professionals alike for its impressive characteristics and technological advancements.

One of the standout features of the KSM109 is its cardioid polar pattern, which effectively isolates the sound source while minimizing background noise and feedback. This makes it an ideal choice for both studio recordings and live performances, ensuring that the microphone captures the desired audio with clarity and precision. The microphone's frequency response ranges from 20 Hz to 20 kHz, providing a broad bandwidth that faithfully reproduces the full spectrum of sounds, from the lowest bass notes to the crispest high frequencies.

The KSM109 employs a Class A, solid-state preamplifier design that enhances its sonic performance. This technology not only contributes to a low self-noise level but also ensures a high output level, making it suitable for a variety of sound sources such as acoustic instruments, vocals, and overheads for drum kits. The microphone features a durable construction with a metal chassis, providing resilience and longevity to withstand the rigors of touring and frequent use in the studio.

Another key characteristic of the KSM109 is its switchable high-pass filter, which allows users to reduce unwanted low-frequency rumble or handling noise. This added flexibility makes it a great tool for various recording situations, enabling engineers to achieve cleaner, more focused sound.

The microphone also includes a ten-decibel pad that allows it to handle high sound pressure levels, making it suitable for loud sources such as brass instruments or guitar amplifiers without distortion. This capability is particularly valuable in live sound scenarios where maintaining audio integrity is crucial.

Overall, the Shure KSM109 is a versatile and reliable microphone that combines advanced technology with user-friendly features. Whether for studio recordings, live performances, or broadcast applications, it stands out as a top choice for professionals seeking quality and performance in their audio equipment.
