The Cardioid Flagship of the LCT Series
As the true flagship with unique directivity in the LEWITT range, the LCT 540 S establishes itself as a modern reference for studio sound capture. Its advanced electronic design and meticulous capsule alignment aim for a clear objective: to push the self-noise threshold below the perceptible level while maintaining a high sensitivity of 41 mV/Pa.
Who Is It For and What For?
Ideal for lead vocals, demanding acoustic instruments (guitar, piano, strings), drum overheads, or sound design, this microphone suits engineers seeking a neutral, detailed reproduction that is easily shaped in the mix. Its consistent cardioid pattern facilitates recordings in untreated spaces, while its dynamic range reserve secures sessions with varying levels.
Key Features for Flawless Recordings
Definition and Operating Silence
The combination of a 1" capsule and optimized circuitry offers a signal-to-noise ratio of 90 dB(A). Even after heavy compression, the noise floor remains clean, preserving micro-dynamics and the natural texture of timbres.
Handling Powerful Sources
With a maximum sound pressure level of 136 dB SPL at 0 dB attenuation, the LCT 540 S handles intense sources without distortion. Switchable -6 and -12 dB pads increase headroom before saturation and facilitate adaptation to different preamps.
Controlled Low End, Cleaner Capture
The three-position high-pass filter (linear, 80 Hz, and 160 Hz at 6 dB/octave) reduces sub-bass, rumble, and proximity effect for a cleaner foundation right from the recording stage.

Questions frequently asked
Is the Lewitt LCT 540 S suitable for vocal recording?
Its cardioid pattern and sensitivity of 41 mV/Pa make it ideal for lead vocal recordings. The signal-to-noise ratio of 90 dB(A) helps maintain a clean background, even with heavy compression.
What is the self-noise level of the Lewitt LCT 540 S microphone?
The specified signal-to-noise ratio is 90 dB(A), combined with a dynamic range of 132 dB. This setup supports capturing subtle nuances on quiet sources.
Can this microphone record acoustic guitar or piano?
The 1-inch large diaphragm capsule covers a frequency response from 20 Hz to 20 kHz. This model suits acoustic guitars, piano, and string instruments requiring detailed reproduction.
What pad and high-pass filter settings are available?
There are three pad settings: 0 dB, -6 dB, and -12 dB. The high-pass filter is switchable between flat, 80 Hz, and 160 Hz with a 6 dB/octave slope, allowing limitation of sub-bass and proximity effect at the source.
Can the LCT 540 S handle high sound pressure levels?
With a maximum SPL of 136 dB without attenuation, this microphone can handle loud sources before distortion. The -6 dB and -12 dB pads provide additional headroom for more intense recordings.
