The LCT 840 nails the huge, warm sound of a classic tube condenser mic and serves it up with breathtaking airy detail. It doesn't skimp on features, either.

With five polar patterns, two levels of attenuation, and two switchable highpass filters, the Lewitt LCT 840 is ready for any session, and its robust build quality makes it ideal for your live work as well.

The Lewitt LCT 840 belongs in your mic locker.

Lewitt's LCT 840 is a premium-class externally polarized dual-diaphragm tube microphone designed to excel in a variety of demanding applications.

It is equipped with a precision-engineered 1-inch capsule and therefore stands for exceptionally warm and classic, solid vintage sound.

The LCT 840 is 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.

There are five switchable polar patterns, omni-directional, cardioid, figure-8, wide-cardioid and super-cardioid, which makes the LCT 840 a highly versatile tool for professional audio engineers and performers looking for true and authentic tube sound.
