Lewitt LCT 540 SUBZERO
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.
// 1″ true condenser studio microphone with cardioid polar pattern
// 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
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 SUBZERO, 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.
