  • Developed in close cooperation with world-renowned producers and audio engineers
  • First and foremost designed to be an outstanding vocal microphone.
  • Naturally, thanks to its specifications, it is suitable for almost any application.
Rediscover Sound and Experience all details
The engineering of this particular piece of cutting-edge audio technology asked for a forward-thinking approach towards capsule and circuit design. As a result, a way of experiencing sound at infinite depth and absolute precision came to life; its name, the LCT 540 S. Get involved with tone and sound in ways unheard and bring your recordings to perfection by capturing all the fine-grained characteristics that constitute each moment of your performance. Rediscover your instrument and voice on a whole new level of musical detail.

Unique self-noise architecture
To see how good our hearing is in a purely technical way we can look at the threshold of hearing. Bear in mind that our hearing threshold is very frequency dependent. Human hearing is less sensitive towards low and very high frequencies and most sensitive around 2 – 5 kHz. Comparing the hearing threshold to the self-noise values of the LCT 540 S, you can clearly see that our microphone is always below the threshold of hearing. The entire frequency spectrum is important, here, because looking at a microphone’s self-noise as a single value just isn’t detailed enough when discussing high-end sound transducers.

Push it to the limit - With 9900 pounds of measurement
The better the microphone, the more difficult self-noise measurement gets. You need a place where no outside noise will interfere with the measurement result. This is especially difficult for lower frequencies. To measure the self-noise of the LCT 540 S, we needed to build a unique measurement device that is more than ten times more massive than conventional ones, weighing over 4500 kg or 9900 pounds in total. It heavily dampens frequencies up to a 1/10,000th of their sound pressure. The whole frequency range of a microphone from 20 Hz to 20,000 Hz is dampened by 60 dB, up to 80 dB on the higher frequencies.

Why is low self-noise important?
When you climb a mountain, and the weather is clear, your reward is a fantastic view. If it is partly cloudy or foggy, the payoff is profoundly reduced. The same goes for recording. Some peaks stick out of the noise floor (fog), but if you remove as much noise as possible, you will be rewarded with details that were buried before. This microphone can pick up the subtlest details in vocals or instruments, an almost inaudible whispering can be pushed up and sound crystal clear. Many noise issues only reveal themselves in post-production. Once you start compressing the signals a previously inaudible noise floor can appear; not with the LCT 540 S.

The LCT 540 S captures every sound source with absolute precision - because it is built with absolute precision; not even the tiniest detail of your recorded source will get lost. To guarantee its ultra-resolution sound and first-class sonic imaging, every 3 μm gold-sputtered, 1" Mylar diaphragm underlies the strictest quality controls.

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. Pair up any two and create balanced stereo and surround recordings.

What's in the box
The LCT 540 S comes in a military-grade protective case, with a shock mount that reduces structure-borne noise to a minimum, and a magnetic pop-filter that integrates perfectly with the design of the microphone.
