The LCT 840 Reference Class Tube Microphone from Lewitt is a premium class externally polarized microphone for vocals and miking instruments in the studio or on stage. Equipped with a precision-engineered 1.0″ capsule, the LCT 840 delivers a classic vintage sound. This multi-purpose microphone offers versatility, letting you choose between five different polar patterns – cardioid, omnidirectional, figure 8, wide cardioid, and supercardioid. This unit has a low self-noise of 9 dB and rejection of off-axis sounds. The microphone’s PSU power supply unit offers three levels of attenuation and three switchable high-pass filters, indicators and push buttons for noiseless handling. The microphone and the PSU unit are connected via an included 26′ 11-pin XLR cable.

The LCT 840 is equipped with a plexiglass inspection window on the front of the body that fully exposes the illuminated tube. The inside window surface is coated with a highly conductive, yet transparent film preventing electromagnetic interference.
