Lewitt LCT 840

Large Diaphragm Tube Sound Condenser Microphone

The Lewitt LCT 840 is a high-calibre, externally polarized, dual-diaphragm tube microphone engineered to perform in all manner of recording applications. With it's precision engineered 1" capsule, the LCT 840 offers oustanding warm and elegant vintage sound. An excellent choice for recording vocals and instruments alike, the LCT 840 provides exceptionally detailed and authentic reproductions in the studio or on the stage.

Featuring a seperate power supply with 5-switchable polar patterns (omni-directional, cardioid, figure-8, wide-cardioid and super-cardioid), the LCT 840 is a highly versatile microphone providing sound engineers and musicians the authentic, true tube sound they seek with as many variations on recording setup as possible.

Lewitt are known for their characteristicly low self-noise microphones with extremely effective rejection of off-axis sounds and the LCT 840 is no exception with a self-noise level of 9dB. The sturdy and elegant standalone power supply offers both 3 SPL attentuation and 3 high-pass filters as well as LEDs and noiseless pushbuttons for attentuation or use of the high pass filters during recordings.

Aside from a level of user-friendly controls and advanced technical features customary on high end microphones, the LCT 840 looks as good as it sounds. With the conductive-treated - for prevention of electromagnet interference - plexiglass window on the front for viewing the illuminated, fully exposed tube and an extra-large hexagonal ruthenium-galvanized steel mesh grille to provide an open acoustic environment and prevents unwanted internal reflections, the LCT 840 presents a unique blend of innovative design, high-end technology and archetypal tube sound that no studio should be without.

Features:

• Ultra-thin 1-inch externally biased, gold-layered low-mass diaphragms combined with a dual triode tube ensures accurate transient response while providing smooth, warm and airy tube sound
• Five consistent directional characteristics – cardioid, omnidirectional, figure-8, broad cardioid and supercardioid – offer maximum flexibility
