Setting Low-Frequency Response, Setting Attenuation

Setting Low-Frequency Response

A three-position switch on the KSM141 lets you adjust the low frequency response of the microphone. The low frequency filters can be used to reduce wind noise, room noise, or proximity effect. Refer to Figure 2.

Flat response. This setting provides the most natural sound reproduction in most applicatons.

Low-frequency cutoff. This

setting provides an 18 dB-per-octave cutoff at 80 Hz. It helps eliminate floor rumble and low-frequency noise produced by heating and air conditioning systems. This setting may also be used to compensate for proximity effect or to reduce low frequencies that make an instrument sound dull or muddy.

Low-frequency rolloff. This

setting provides a 6 dB-per-octave rolloff at 115 Hz. Use this setting 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 by up to 25 dB without altering frequency response. This can prevent extremely loud sounds from overloading the microphone. Set the switch to the desired attenuation levels as follows:

0 dB - Move the switch to this position for “quiet” to “normal” sound levels.

-15 dB - Move the switch to this position when the microphone is approximately 0.75 meters (2 feet) from sound sources such as a kick drum, snare drum, or electric guitar cabinet.

-25 dB - Move the switch to this position when the microphone is 4 inches (10 cm) or less from extremely loud sound sources such as kick drum, snare drum, or guitar cabinets.

KSM141 specifications

The Shure KSM141 is a versatile and innovative condenser microphone that stands out in various audio environments, making it a popular choice among professionals. Known for its exceptional sound quality and adaptability, the KSM141 is particularly suited for both studio and live applications.

One of the main features of the Shure KSM141 is its switchable polar pattern, allowing users to choose between cardioid and omnidirectional pickup configurations. This flexibility enables the microphone to capture sound more effectively in different settings, whether it's isolating a vocal performance in a live mix or capturing ambient sound in a recording session.

The KSM141 utilizes a state-of-the-art, low-noise JFET preamplifier design, which provides a wide dynamic range and ensures clarity in sound reproduction. This technology allows the microphone to handle high sound pressure levels while minimizing distortion, making it suitable for a variety of sound sources, including vocals, acoustic instruments, and percussion.

Another significant characteristic of the KSM141 is its advanced shock mounting system. This feature helps to isolate the microphone from handling noise and vibrations, ensuring a clean and noise-free recording. The microphone's durable construction is designed to withstand the rigors of everyday use, with a rugged metal housing that protects it from physical damage.

The KSM141 also boasts an impressive frequency response range of 20 Hz to 20 kHz. This broad frequency response ensures that every nuance of the sound is captured, from the deep lows of a bass guitar to the crisp highs of a cymbal crash. Additionally, the microphone's self-noise level is incredibly low, enabling it to capture delicate sounds without interference.

Equipped with a high-pass filter and a 20 dB pad, the KSM141 provides further adaptability in various recording situations. The high-pass filter helps reduce low-frequency rumble, while the pad is essential for handling louder sound sources without distortion.

In summary, the Shure KSM141 is a remarkable microphone that combines versatile pickup patterns, exceptional sound quality, and robust construction. Whether for studio recording, stage performances, or capturing field audio, the KSM141 meets the needs of audio professionals, making it a reliable and valuable tool in any audio toolkit.
