Lewitt LCT840 Large Diaphragm Tube Sound Microphone

The dual triode 12AX7 tube delivers comforting sound with smooth high frequencies, while still preserving the ability to cut through the mix.

Low self-noise and high dynamic range exemplify how the LCT 840 is classic design brought into the present.

The externally polarized dual-diaphragm 1″ capsule captures every nuance of your performance thanks to its 3-micron-thin, gold-layered, low-mass diaphragms. It handles everything from vocals to full orchestras.

Warmth and precision in all situations. The LCT 840 is fully devoted to warm tube sound. We use a dual triode 12AX7 tube to create that warm and comforting sound with smooth high frequencies while still preserving the ability to cut through the mix.
