The product

LEWITT’s LCT 340 is a 0.8-inch externally polarized condenser microphone that excels at capturing
acoustic and percussion instruments, drums and vocals, and is perfectly suited for sophisticated live and
studio applications. Two interchangeable capsules allow for quick and easy switching of patterns,
ensuring greater flexibility without changing microphones.

The LCT 340 is equipped with four-position low-cut filter and pre-attenuation slide switches, dual-color
LED indicators and a convenient snap closure. It offers a dynamic range of 124 dB and stands out for its
extremely low self-noise of 15 dB. Last but not least, its transformerless output makes this ruggedly
designed pro-mic resistant to electrical interference and a first-class pick for true sound enthusiasts.

High-pass filter indications

The currently active high-pass setting is illuminated.

Setting a high-pass filter

High-pass filters can be set by adjusting the recessed slide

switch. Settings are: Off, 12 dB / octave at 40 Hz and 6 dB /

octave at 150 and 300 Hz. High-pass filters eliminate unwanted low

frequency noise such as structure borne noise.

Illumination push button

By briefly pressing the recessed illumination push button the

illuminated indications can be turned on or off.

Attenuation indications

The currently active attenuation setting

is illuminated.

Setting an attenuation level

Attenuation levels can be set by adjusting the
recessed slide switch. Settings are: off, -6 dB,
-12 dB and -18 dB. Attenuation is used in extremely
high SPL environments in order to prevent clipping of
the microphone, mixer and other audio equipment.
