Designed to excel in a variety of demanding applications, Lewitt's LCT 840 is a premium-class externally polarized dual-diaphragm tube microphone that's equipped with a precision-engineered 1" capsule. It stands for exceptionally warm and classic, solid vintage sound. Highly suited for vocal and instrument mic applications, this rugged multi-purpose mic allows for highly nuanced and authentic sound reproduction in the studio and even on stage. It has 5 switchable polar patterns – omni-directional, cardioid, figure-8, wide-cardioid and super-cardioid – making it a highly versatile tool for professional audio engineers and performers looking for true, authentic tube sound. Like all Lewitt microphones, the LCT 840 stands out thanks to its extremely low self-noise level of 9 dB and effective rejection of off-axis sounds. It features 2 levels of attenuation and 2 switchable low-cut frequencies, LEDs and pushbuttons for noiseless handling on the power supply unit (PSU). Apart from its user-friendly operating controls and advanced technological features so essential to memorable recordings, it also makes an eye-catching design statement: it's equipped with a plexiglass inspection window on the front side of the body, so the illuminated tube itself is fully visible. The inside window surface is coated with a highly conductive, yet transparent film to prevent electromagnetic interference.

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