KSM44A specifications

The Shure KSM44A is a professional condenser microphone that has gained prominence among recording engineers and musicians for its versatility and high-quality sound reproduction. This microphone embodies Shure's commitment to excellence, offering features that cater to both studio and live performance applications.

One of the standout features of the KSM44A is its switchable polar patterns. It provides three settings: cardioid, omnidirectional, and bidirectional. This adaptability allows users to capture sound from different directions, making it suitable for various recording environments and techniques. Whether you are recording vocals, instruments, or an ensemble, the KSM44A's flexible pickup patterns enable precise sound capture tailored to the situation.

Equipped with a high-performance diaphragm, the KSM44A ensures exceptional audio clarity and sensitivity. The microphone's wide frequency response range, from 20 Hz to 20 kHz, allows it to capture the full spectrum of human hearing, ensuring that every nuance of sound is recorded accurately. This characteristic is especially valuable in studio settings, where clarity and detail are paramount.

The KSM44A utilizes Shure's advanced suspension system, which significantly reduces handling noise and vibrations. This technology ensures that unwanted noise does not interfere with the recording, delivering a clean and pristine audio signal. Additionally, the microphone features a robust build quality, making it suitable for both studio and on-stage applications.

Another notable technology is the KSM44A's built-in pop filter and windscreen, which helps to minimize plosive sounds caused by vocal bursts. This feature is beneficial when recording vocals, allowing for clearer takes without frequent interruptions due to unwanted noise.

For those concerned about phantom power, the KSM44A operates on standard 48V phantom power, common in professional audio setups. With a high maximum SPL (sound pressure level) handling, the microphone can easily capture loud sound sources without distortion, making it perfect for electric guitar amplifiers, brass instruments, and even percussion.

In summary, the Shure KSM44A is an exceptional microphone that embodies versatility, quality, and durability. Its switchable polar patterns, wide frequency response, advanced suspension system, and additional features make it an ideal choice for professional audio applications. Whether in a recording studio or a live performance, the KSM44A delivers outstanding sound quality that meets the demanding needs of today's audio professionals.
