LEWITT LCT 540 S - Microphone without audible self noise
LEWITT LCT 540 S - Microphone without audible self noise

The quietest studio microphone ever made.

Our unique approach towards electronics and capsule design makes the LCT 540 S the quietest studio recording microphone. It lets you capture all the fine-grained details of your voice and instruments that usually wouldn’t even be audible.

The studio microphone without audible self-noise.

Our hearing threshold is very frequency-dependent. It is less sensitive to low and very high frequencies and most sensitive around 2 – 5 kHz. With our specific and unique approach toward circuit and capsule design, the LCT 540 S features self-noise below the hearing threshold across the entire frequency spectrum. 

Perfect Match
Perfect Match

Easily create stereo pairs.

Every single LCT 540 S undergoes a series of measurements followed by an adjustment of the polarization voltage to achieve the same sensitivity in every microphone. This is what we call our Perfect Match technology. If you add more LCT 540 S to your collection, you can use any two of them as a stereo pair.

Fit for extreme processing of vocals and more.

With its cutting-edge circuit and capsule design, the LCT 540 S  features an impressive dynamic range of 132 dB to capture everything from loud to subtle. You won’t hear the self-noise of the mic even after heavily compressing the signal. Material recorded with the LCT 540 S is fit for modern productions that feature heavy processing.
