Selecting Low-Frequency Response

A three-position switch on the back of the microphone lets you adjust the low-frequency response. Use the low-frequency filter to reduce wind noise, room noise, or proximity effect.

Flat response. Provides the most natural sound in most applications.

Low frequency cutoff. Provides an 18 dB-per-octave cutoff at 80 Hz. Helps eliminate floor rumble and low- frequency room noise from heating and air condition- ing systems. This setting may also be used to com- pensate for proximity effect or to reduce low frequen- cies that make an instrument sound dull or muddy.

Low frequency rolloff. Provides a 6 dB-per-octave rolloff filter at 115 Hz. Use this to compensate for proximity effect or to reduce low frequencies that could make an instrument sound dull or muddy.

Setting Attenuation

The attenuation switch lets you reduce the signal level without altering the frequency response. This can prevent extremely loud sounds from overloading the microphone.

0 dB For “quiet” to “normal” sound levels.

-15 dB For use with extremely loud sound sources such as drums, horns, or loud guitar cabinets.

Load Impedance

Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance of the preamplifier to which you connect the microphone. Shure recommends a minimum input load impedance of 1000 Ω. Most modern microphone preamplifiers meet this requirement. Higher impedance results in better performance for these specifications.

Integral Pop Filter

The microphone grille consists of 3 separate mesh layers that act as an integral pop filter. This helps reduce wind and breath noise. Depending on the performer, an external pop-protection screen or windscreen may be necessary when close-miking vocalists.

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.
