LCT 840

The product 

LEWITT’s LCT 840 is a premium-class externally polarized dual-diaphragm tube microphone designed to excel in a 

variety  of  demanding  applications.  Equipped  with  a  precision-engineered  1-inch  capsule,  the  LCT  840  stands  for 

exceptionally warm and classic, solid vintage sound. Perfectly suited for miking vocals and instruments, this rugged 

multi-purpose  microphone  allows  for  highly  nuanced  and  authentic  sound  reproduction  in the  studio  and  even  on 

stage.  Five  switchable  polar  patterns  –  omni-directional,  cardioid,  figure-8,  wide-cardioid  and  super-cardioid  – 

make  the  LCT  840  a  highly  versatile  tool  for  professional  audio  engineers  and  performers  looking  for  true  and 

authentic tube sound.

Like all LEWITT mics, the LCT 840 stands out for its extremely low self-noise of 9 dB and effective rejection of off-axis 

sounds.  The  microphone  features  three  levels  of  attenuation  and  three  switchable  high-pass  filters,  LEDs  and 

pushbuttons for noiseless handling on the power supply unit (PSU).

Apart  from  user-friendly  operating  controls  and  advanced  technological  features  so  essential  to  memorable 

recordings,  the  LCT  840  also  makes  an  eye-catching  design  statement:  The  microphone  is  equipped  with  a 

plexiglass inspection window on the front side of the body, so the illuminated tube itself is fully exposed. The inside 

window surface is coated with a highly conductive, yet transparent film preventing electromagnetic interference.

In short: The unique combination of innovative design, high-end technology and tube-typical sound quality ensures 

magic takes.
