Quality Is A Permanent Task


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.
