LCT 640

LEWITT’s LCT 640 is designed to raise the bar in its class of reference-quality large-diaphragm condenser microphones. 
This  Austrian-designed  and  engineered  pro-mic  delivers  a  smooth,  unsurpassably  rich  and  exceptionally  nuanced 
sound, and exhibits a remarkable set of qualities that enthuses even the most discerning users. The LCT 640 excels in a 
variety of demanding studio applications and stands for unrivalled performance in miking lead and background vocals, 
drums, percussion instruments, grand pianos, brass and woodwinds, classical music ensembles.

In addition to the standard omni-directional, cardioid and figure-8 polar patterns, the LCT 640 offers a wide-cardioid and 
super-cardioid characteristic. It offers a dynamic range of 135 dB and stands out for its extremely low self-noise of 10 dB. 
In combination with a  4-level  high-pass filter  and  4-level  switchable  pre-attenuation, the  LCT  640  provides maximum 
versatility in all recording situations. Automatic attenuation, key-lock, clipping history, push buttons and a light-up user 
interface round off the features of this outstanding microphone.
