The Shure KSM141/SL is a dual-pattern condenser instrument microphone featuring a mechanical polar pattern switch that allows easy transition between cardioid and true omnidirectional modes. With its ultra-thin 24K gold-layered Mylar diaphragm, transformerless preamplifier, extended frequency response, and low self-noise, the KSM141 is ideal for both studio recording and live applications.
It handles extremely high SPLs with a three-position pad and includes a subsonic filter to eliminate low-frequency rumble caused by mechanical vibrations.
Dual-Pattern Flexibility – Switchable cardioid and omnidirectional polar patterns
Gold-Layered Mylar Diaphragm – 2.5 μm, 24K gold for superior transient response
Transformerless Preamplifier – Class A discrete design for transparency & minimal distortion
Extended Frequency Response – Smooth response from 20 Hz–20 kHz
Low Self-Noise – Captures every detail with clarity
High SPL Handling – Three-position pad (0 dB, -15 dB, -25 dB) for extreme sound levels
Subsonic Filter – Eliminates vibrations below 17 Hz
Three-Position Low-Frequency Filter – Reduces background noise & proximity effect
Rugged Construction – Suitable for studio or stage use
Versatile Applications – Acoustic, wind, percussion, strings, orchestral, and ambient recording
