LCT 140 The product
The LCT 140 is an extremely versatile, easy-to-use, compact 2/3-inch back-electret condenser
microphone, perfectly suited for quality-conscious casual users. Its low-mass diaphragm delivers an
exceptionally clear and natural sound, making it the perfect fit for a wide range of live and studio
applications including drums and percussion, acoustic instruments or even vocal ensembles.
Thanks to its uniform cardioid pickup pattern that effectively suppresses off-axis sound, a wide dynamic
range of 124 dB and its very low self-noise, the LCT 140 adds transparency and distortion-free detail to
every sound recording. Its transformerless output design makes it immune to electromagnetic
interference. The LED display can optionally be switched on and off for better handling in different
environments. In short, the LCT 140 is an extremely versatile all-rounder microphone.

octave at 300 Hz. High-pass filters eliminate unwanted low
frequency noise such as structure borne noise.
Illumination push button
·By briefly pressing the recessed illumination push button
the illuminated indications can be turned on or off.
Attenuation indications
