Like all LEWITT mics, the LCT 840 stands out for its extremely low self-noise level of 9 dB and effective rejection of off-axis sounds. The microphone features two levels of attenuation and two switchable low-cut frequencies, 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 mic 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.
