Lewitt LCT 540 S Large Diaphragm Condenser Microphone

Cutting-edge large diaphragm condenser microphone for ultra-detailed sound images

Product Description

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 Lewitt LCT 540. 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.


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, you can clearly see that this 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.


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 540BURL, Lewitt 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.


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 540BURL.


The LCT 540BURL 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.


Every single LCT 540BURL undergoes a series of measurements followed by adjustment of the polarization voltage to achieve the same sensitivity in every LCT 540BURL Lewitt will ever produce.

The Lewitt LCT 540BURL is a cutting-edge large diaphragm condenser microphone capable of capturing the quietest, most intimate sounds with absolute precision. Designed from the ground up for outstanding vocal recordings, the LCT 540BURL also sounds great on piano, acoustic guitar, percussion and more. With an expansive dynamic range, excellent transient response, and almost zero self-noise, the LCT 540BURL delivers unlimited detail.


The LCT 540BURL features a unique self-noise architecture to ensure maximum sensitivity across the entire frequency spectrum. By removing as much noise as possible, it can pick up details in vocals or instruments that are imperceivable to the human ear. Even after applying compression and limiting in post production, the LTC 540BURL never reveals its noise floor.

In order to deliver world-class sonic imaging, the LTC 540BURL is equipped with a 3 μm gold-sputtered one-inch Mylar diaphragm. This state-of-the-art design offers an unparalleled dynamic range of 132 dB, and excellent transient response, making the LTC 540BURL the perfect vocal microphone.


Monitor your recording directly from the mic itself with an integrated clipping indicator. Protect your performance from peaks with an automatic attenuation function. Keep your vocals sounding crips and clear by eliminating unwanted low end with two dedicated low-cut filter settings. While the LTC 540BURL excels at recording quiet sound sources, it’s also capable of capturing explosive transients with two pad settings for up to 12 dB of gain reduction.


The LCT 540BURL includes a military-grade protective case for safekeeping. The LCT 40 SH shock mount reduces unwanted noise from rumbling mic stands. Unlike traditional shock mounts, the LCT 40 SH features an open front, which enables you to place the microphone as close to the source as possible to take advantage of the proximity effect when recording amps, vocals and instruments.

A custom magnetic pop filter reduces plosives and protects the capsule from moisture when recording vocals. The LCT 50 PSx pop filter perfectly integrates with the microphone to improve audio quality without covering up half of the singers face.

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
