Product Description

REDISCOVER SOUND

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.

BETTER THAN HUMAN HEARING

SUBZERO 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

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.
