Lewitt LCT 540 SUBZERO Large-Diaphragm Condenser Microphone
The LCT 540 SUBZERO is the flagship single-pattern 1” true condenser studio microphone in Lewitt's product line. Its cutting-edge circuit design is an outstanding achievement on all technical levels. It drops self-noise below the threshold of human hearing at a sensitivity of 40 mV/Pa, -28 dB/Pa, and increases the dynamic range to 132 dB - a new benchmark for studio-grade large-diaphragm condensers.
Features:
- 1" true condenser studio microphone
- Self-noise below the threshold of human hearing
- Ideal for extreme processing
- Low-cut filters and attenuation
- Cardioid polar pattern

Manufacture Description
Even the subtlest nuances sound crystal clear.
With its cutting-edge circuit and capsule design, the LCT 540 S features an impressive dynamic range of 132 dB to capture everything from loud to subtle. You won’t hear the self-noise of the mic even after heavily compressing the signal. Material recorded with the LCT 540 S is fit for extreme processing.
Your mic for ultra-detailed studio recordings.
Our unique approach towards electronics and capsule design makes the microphone better than human hearing. With the LCT 540 S, we set a new benchmark in terms of capturing fine-grained details of your recording source.
Record details of your voice and instruments that usually wouldn’t even be audible. Make every detail count.
Self-noise values below the threshold of human hearing.
Our hearing threshold is very frequency-dependent. It is less sensitive towards low and very high frequencies and most sensitive around 2 – 5 kHz. With our specific and unique approach towards circuit and capsule design, we were able to realize self-noise that'll stay below the threshold of hearing across the entire frequency spectrum.
We had to elevate measurement to a new level.
To measure the self-noise of the LCT 540 S, we built a unique device. It's ten times more massive than conventional ones, weighing over 4500 kg or 9900 lbs in total. This amount of mass will dampen frequencies up to a 1/10,000th of their sound pressure. The frequency range from 20 Hz to 20,000 Hz is dampened by 60 dB, up to 80 dB on the higher frequencies.
