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 SUBZERO. 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 HEARINGSUBZERO SELF-NOISE ARCHITECTURETo 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 SUBZERO, you can clearly see that our microphone is always below the threshold of hearing. To look at the self-noise of a microphone in a single value is just not detailed enough when discussing high-end sound transducers.
THE TIP OF THE ICEBERGWHY 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 SUBZERO.
