LCT 840

What you see is what you get

Super-low self-noise multi-pattern tube microphone with a spectacular view.


Classic microphone with modern features

The LCT 840, equipped with a precision-engineered 1″ capsule, stands for exceptionally warm and classic tube sound. It offers highly nuanced and authentic sound reproduction in the studio and even on stage. 5 switchable polar patterns, 3 low-cut settings, and 3 pre-attenuation settings make the LCT 840 a highly versatile tool. 

Honest tube sound

The dual triode 12AX7 tube delivers a warm and 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 vintage design brought into the present.

The future of vintage

Innovation and heritage brought together

The LCT 840 is just like its place of origin - Vienna, Austria - a mixture of old and new, traditional heritage and high-tech. We love rich tube sound and we love modern design. Combining them both in the LCT 840 is a dream come true for all recording professionals.

LCT 840 box content

"OK, how does it sound? In a word, fantastic. Warmest, smoothest, tube mic I've ever used. I do a lot of vintage type stuff like bluegrass, vintage country etc. The 840 is perfect for vocals for a vintage vocal sound. No hype on the high end. No muddyness on the low end. Just a perfectly balanced albeit warm and somewhat dark sound. Running through a tube/transformer preamp results in vintage sound dripping with warmth and mojo."
