Fixed cardioid pattern, designed primarily as a vocal microphone, with onboard PAD and low-cut filters and LEWITT's Perfect Match Technology enabling matched stereo pairs with any other LCT 540 S unit.\u003c\/p\u003e\n\n  \u003ch3\u003e4 dB(A) Self-Noise – What It Means in the Signal Chain\u003c\/h3\u003e\n  \u003cp\u003eA well-regarded studio condenser typically lands between 7 and 12 dB(A) of self-noise. The LCT 540 S achieves 4 dB(A) – a figure matched by only a handful of microphones on the market at any price point. The practical consequence is straightforward: heavy compression, long signal chains, layered vocal stacks, heavily processed instruments – all of these amplify whatever noise the microphone introduces. At 4 dB(A), that noise stops being a variable. The high sensitivity of 41 mV\/Pa means the preamp gain needed to reach a workable recording level stays lower, which further contributes to a cleaner final signal. The 132 dB(A) dynamic range covers the full spectrum from the quietest whisper to loud amplified sources – without reaching for a different microphone.\u003c\/p\u003e\n\n  \u003ch3\u003ePerfect Match Technology and Stereo Pairing\u003c\/h3\u003e\n  \u003cp\u003eEvery LCT 540 S unit manufactured undergoes individual measurement and automated polarization voltage calibration to achieve identical sensitivity at 1 kHz. In practice this means a second LCT 540 S purchased months or years later will form a matched stereo pair with the first one – no unit selection, no sensitivity offset to compensate for. The LED embedded in the LEWITT logo doubles as a clipping indicator. The complete set includes a shockmount, magnetic pop filter, foam windscreen, leatherette bag, and a mil-spec hard transport case.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eSelf-noise: 4 dB(A) – below the threshold of human hearing across the full frequency range\u003c\/li\u003e\n    \u003cli\u003e1\" true condenser capsule, 3 µm gold-sputtered Mylar diaphragm, 25.4 mm\u003c\/li\u003e\n    \u003cli\u003ePolar pattern: cardioid\u003c\/li\u003e\n    \u003cli\u003eHigh sensitivity: 41 mV\/Pa (–28 dBV\/Pa)\u003c\/li\u003e\n    \u003cli\u003eDynamic range: 132 dB(A) – from whisper-quiet sources to loud transients without changing mics\u003c\/li\u003e\n    \u003cli\u003ePerfect Match Technology – guaranteed identical sensitivity across all units, stereo pairing with any LCT 540 S\u003c\/li\u003e\n    \u003cli\u003ePAD: 0 dB \/ –6 dB \/ –12 dB\u003c\/li\u003e\n    \u003cli\u003eLow-cut filter: linear \/ 80 Hz \/ 160 Hz (6 dB\/oct)\u003c\/li\u003e\n    \u003cli\u003eLED clipping indicator built into the logo\u003c\/li\u003e\n    \u003cli\u003eZinc die-cast housing, gold-plated XLR connector\u003c\/li\u003e\n    \u003cli\u003eIncludes: shockmount, magnetic pop filter, windscreen, leatherette bag, mil-spec transport case\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eTransducer type: condenser, externally polarized\u003c\/li\u003e\n    \u003cli\u003eOperating principle: pressure gradient transducer\u003c\/li\u003e\n    \u003cli\u003eDiaphragm: 3 µm gold-sputtered Mylar, 25.4 mm (1\")\u003c\/li\u003e\n    \u003cli\u003ePolar pattern: cardioid\u003c\/li\u003e\n    \u003cli\u003eFrequency range: 20 Hz – 20,000 Hz\u003c\/li\u003e\n    \u003cli\u003eSensitivity: 41 mV\/Pa (–28 dBV\/Pa)\u003c\/li\u003e\n    \u003cli\u003eSelf-noise: 4 dB(A)\u003c\/li\u003e\n    \u003cli\u003eMaximum SPL (0.5% THD): 136 dBSPL (0 dB attenuation)\u003c\/li\u003e\n    \u003cli\u003eSignal-to-noise ratio: 90 dB(A)\u003c\/li\u003e\n    \u003cli\u003eDynamic range: 132 dB(A)\u003c\/li\u003e\n    \u003cli\u003eAttenuation pad: 0 dB \/ –6 dB \/ –12 dB\u003c\/li\u003e\n    \u003cli\u003eLow-cut filter: linear \/ 80 Hz \/ 160 Hz (6 dB\/oct)\u003c\/li\u003e\n    \u003cli\u003eInternal impedance: 68 Ω\u003c\/li\u003e\n    \u003cli\u003ePower supply: 48V phantom ±4V\u003c\/li\u003e\n    \u003cli\u003eCurrent consumption: 3.6 mA\u003c\/li\u003e\n    \u003cli\u003eEnclosure: zinc die cast\u003c\/li\u003e\n    \u003cli\u003eConnector: gold-plated 3-pin XLR\u003c\/li\u003e\n    \u003cli\u003eDimensions: 158 × 52 × 36 mm (6.22\" × 2.04\" × 1.42\")\u003c\/li\u003e\n    \u003cli\u003eWeight: 371 g (13.1 oz)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n\u003c\/div\u003e","brand":"LEWITT","offers":[{"title":"Default Title","offer_id":53446341984593,"sku":"59307","price":675.68,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/LEWITTLCT540S1.jpg?v=1775468749","url":"https:\/\/wrdtunes.com\/en-fr\/products\/lewitt-lct540s","provider":"Wired Tunes","version":"1.0","type":"link"}
