The LCT 840 is a classic

I'm songwriter/vocal producer Mischke. I have to be honest the Lewitt LCT 840 I've been using is not my mic. The mic is owned by my friend and producer Neff-U. I can't tell you how much I love this mic. I first used it on Verve recording artist Charles Perry. I'd been told that they'd used it on his record during the early sessions. I was hired to re-record and vocal produce the record. I'm not the type to just trust others opinions on mics so I planned to test 3 mics and pick the best. The Lewitt 840 was the 1st mic. It sounded so amazing I told them to take the other 2 mics down. Charles is one of the most dynamic singers I've ever worked with. If it can handle his power and capture the beauty of the air in his falsetto, it's perfect for anyone. It's like having the body of a Neumann 47 and the top end of a 251 Elam, all in one package. This mic is also like stepping into the future. The technology in this mic is really second to none. If you need a mic that’s a workhorse from the future with the sound of yesterday, this is the mic for you. I'll be finished Neff-U's record next week so it's gonna go home soon but I'm in love with this mic.

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.
