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.
