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.

Fit for extreme processing.
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 extreme processing.

Perfect match technology.
Every single LCT 540 S undergoes a series of measurements followed by adjustment of the polarization voltage to achieve the same sensitivity in every LCT 540 S we will ever produce. This way, you can form a pair when you buy another one later on.
