Rediscover your instrument and voice

Capture even more details than human hearing.

Your mic for ultra-detailed studio recordings.

Our unique approach towards electronics and capsule design makes the microphone better than human hearing. With the LCT 540 S, we set a new benchmark in terms of capturing fine-grained details of your recording source.

Record details of your voice and instruments that usually wouldn’t even be audible. Make every detail count.

Fit for extreme processing

Even the subtlest nuances sound crystal clear.

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.

How is this mic better

Self-noise values below the threshold of human hearing.

Our hearing threshold is very frequency-dependent. It is less sensitive towards low and very high frequencies and most sensitive around 2 – 5 kHz. With our specific and unique approach towards circuit and capsule design, we were able to realize self-noise that’ll stay below the threshold of hearing across the entire frequency spectrum.

Yes, we like science

We had to elevate measurement to a new level.

To measure the self-noise of the LCT 540 S, we built a unique device. It’s ten times more massive than conventional ones, weighing over 4500 kg or 9900 lbs in total. This amount of mass will dampen frequencies up to 1/10,000th of their sound pressure. The frequency range from 20 Hz to 20,000 Hz is dampened by 60 dB, up to 80 dB on the higher frequencies.

Perfect match technology

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 LCT 540 S we will ever produce. This way, you can form a pair when you buy another one later on.
