Multi-Pattern Pencil Condenser Microphone
The Shure KSM141 is an end-addressed electret condenser microphone with a medium diaphragm and mechanically switched pattern control.
Is is nearly identical to Shure’s KSM137, which has a fixed cardioid pattern. The two mics have identical capsules; the KSM141 achieves an omnidirectional pattern by closing the acoustic vents at the rear of the mic capsule.
Like the KSM137, the KSM141 has a 3-way pad switch (0dB, -15dB, -25dB) and a max SPL (at -25dB) of 170dB into a 5kOhm load. The mic’s self-noise rating is 14dBA.
A second 3-way switch controls the high-pass filter, which provides two levels of LF attenuation: -6dB/octave at 115Hz, or -18dB/octave at 80Hz. In addition, a nonswitched subsonic filter in the amp circuit attenuates sound below 17Hz.

Sonically, the KSM141 is not exactly transparent, nor is it airy and open sounding. Rather, it tends toward a darker, drier presentation… In fact, the KSM141 made me think of a Shure SM57 on steroids — it’s a bit brighter and faster than that legendary dynamic, but it definitely has a 57 vibe. There’s a kind of hard and flat (one-dimensional) quality in the midrange, and both the highs and lows — especially the lows — sound overly rolled off. In addition, the KSM141 does not exhibit exceptional transient response, at least as compared with similar condensers.
Just the same, the KSM141 did a nice job on a variety of instruments. I loved it on djembe, and its dark quality helped smooth out some harshness on a tambourine. Recordists with particularly bright sound sources — or overly bright recording spaces — may find the mic helpful for taming edginess.
In cardioid mode, this mic feels like a laser. The rejection was almost like a hypercardioid shotgun mic. The rejection is so powerful that off-axis instruments can sound very out-of-focus and muted… Even at a height of ten feet above the drum kit, it was very obvious where each mic was pointed…
[L]ive sound engineers should take note. This mic is an anti-feedback secret weapon.
Omni mode proved to be a much more musical setting for this mic. In omni mode the mic lost its “pinched” sound and opened up.
