Lewitt LCT 540 S Cardioid Condenser Microphone

The Studio Microphone Without Audible Self-Noise

The LEWITT LCT 540 S is the ultimate choice for professional audio engineers and producers demanding maximum detail and clarity in their recordings. Hailed as the quietest studio microphone ever made, the LCT 540 S features an innovative circuit and a meticulously designed 1" true condenser capsule, resulting in an ultra-low self-noise level of just 4 dB (A)—a level below the threshold of human hearing across the entire frequency spectrum.

This exceptional clarity allows you to capture every subtle nuance of vocals, acoustic instruments, or ambient sounds that would typically be masked by the mic's own noise floor. Furthermore, its impressive 132 dB dynamic range ensures your recordings are fit for extreme processing, meaning you can apply heavy compression or EQ without revealing undesirable electronic noise, making it a versatile workhorse for everything from cinematic voice-overs to intricate music production. Its cardioid polar pattern provides excellent off-axis rejection, focusing purely on your source sound.

Key Features
