Your tube mic sounds even better than it looks.

If you are looking for a larger-than-life tube sound, look no further. The LCT 840 stands for exceptionally warm and classic tube sound.

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 a classic design brought into the present.

Full-bodied tube sound with smooth high-end

The LC10 capsule is precision taken to a new level.

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.

Dual triode 12AX7 tube for a warm sound

Get to the heart of that iconic tube sound.

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.

Remote control and power supply in one

Make yourself comfortable.

The user interface on the remote control with integrated power supply allows a quick setup of polar pattern, pre-attenuation, and low-cut.

It is easy to check or change the settings on the remote power supply unit, even in complete darkness due to its illuminated user interface.

Multi-pattern design

Here are your five classic patterns.

A polar pattern affects how much room sound you end up recording. But switching your polar pattern not only changes the directivity, it also alters the frequency response, resulting in a different sound.

You can also control the proximity effect, and have it pronounced or reduced according to your application.
