Overview: The Shure KSM141 is a dual-pattern, end-addressed condenser
microphone designed for studio use, but rugged enough for live applications. It
features a rotating collar switch, that allows the polar pattern to be either
cardioid or omnidirectional, making this mic flexible enough for a wide variety of
recording and live applications. An ultra-thin, 2.5 micron, 24-carat gold
layered, low mass Mylar diaphragm offers superior transient response. With the
ability to withstand extremely high sound pressure levels and an extended
frequency response, the KSM141 is ideal for recording wind and acoustic
instruments, low frequency instruments like kick drums and bass guitars, as well
as for overhead miking and choral or orchestral ensembles.
Polar Patterns: The KSM141's rotating collar-switch lets you select
either a cardioid or omnidirectional polar pattern.
- Cardioid: With this pattern, the microphone picks up sounds
directly in front of it, while rejecting sounds from the sides and rear.
This is most commonly used in studio recording and live sound.
- Omnidirectional: This pattern picks up sounds from all directions
and is best for miking several sources, such as an ensemble or multiple
singers, simultaneously. An omnidirectional pattern is also good for picking
up room ambience and overhead miking of drums.
High-pass Filter: A three-position switch on the mic lets you adjust
the low-frequency response. This helps reduce unwanted bass caused by room
noise, wind, and the proximity effect. The three settings include:
- Flat: No filtering. This provides the most natural sound in most
- Low Frequency Cutoff (1): This setting provides an 18 dB/octave
cutoff at 80 Hz.
- Low Frequency Cutoff (2): This setting provides a 6 dB/octave
cutoff at 115 Hz.
Attenuation Pad: Miking loud sound sources or placing a mic extremely
close to an instrument can subject the diaphragm to very high sound pressure
levels, which may cause audible distortion. The KSM141 includes an 3-position
attenuation switch with 0, -15 dB, and -25 dB settings.
Phantom Power: Because the KSM141 is a condenser microphone, it
requires +48 Vdc phantom power.
Connection: The output connection is a gold plated, 3-pin, male XLR
connector, that offers a balanced, low impedance output.
