Overview

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 unrivaled 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.

Versatile studio mic at a great price!

By drew womack

from Austin, Texas

Let me start by saying I sing studio backing vocals for a living so I have several large diaphragm Mics to choose from. I found this mic in a pawn shop of all places and decided to buy it after I did some research. It's a very strange mic with all its features(too many to list) I set up a shoot out between a U47, a well made C12 clone and my trusty $300 Shure SM7. If you are working in a home studio that's a glorified spare bedroom and u have issues with noise from outside or in, this is the only mic you need. I thought it was off as I was setting them all up. I could hear the ambient noise that the fan was making from all the other Mics besides the SM7. Bottom line... The LCT 640 was very smooth and had great characteristics as far as sound but at the same time has a proximity effect like an SM7. Killer!! Find you one!
