// Intro
Thank you for choosing the LEWITT LCT 450!
The LCT 450 delivers exceptionally high value for money, that makes the LCT 450 a true studio workhorse and
a perfect candidate for building up your microphone collection. The Austrian-developed LCT 450 features a
1-inch cardioid condenser capsule, it delivers everything you would expect from a studio microphone: A warm,
round and full bodied sound with rst class transient response and silky sweet high end, which makes it an
impeccable choice for vocals and all sorts of acoustic instruments.
The cardioid polar pattern perfectly qualies the LCT 450 for coincident (XY) and near coincident (ORTF) stereo
recording techniques such as classic drum & percussion overheads, string sections, choir, grand piano or even
stereo vocal recordings, when spaciousness and ambience is needed.

// User Interface
1Status Indicator // Indicates different active settings such as key lock,
automatic attenuation, clipping history ... see below for details.
2 Low-cut lter // Use to reduce unwanted low frequency noise caused by wind,
footsteps, structure-borne noise or likewise. The low-cut lter at 80Hz affects
the microphone input by 12 dB per octave and can be set by pressing the left
pushbutton .
3Pre-Attenuation // Use this pad function to prevent clipping when recording
very loud sources. Choose between 0 and 20 dB of attenuation. Change settings
with the right pushbutton .
4Left push button // Push to change low-cut settings. It also activates the
Clipping History.
Clipping History // Pressing the left pushbutton for more than two seconds
activates and deactivates the Clipping History. If clipping occurred since you
have checked previously, the Status Indicator blinks red, the manually
set level of pre-attenuation blinks and the suggested attenuation setting is
illuminated. The history will be cleared after leaving the Clipping History.
