Lewitt LCT 840 ไมโครโฟน Reference Class Large Diaphragm Tube Condenser Microphone
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 magical takes.
