The LCT 550 Large Diaphragm Condenser Microphone from Lewitt offers 0 dB of self noise for quiet operation in tracking a variety of sound sources. The microphone has a cardioid polar pattern and features 3 levels of selectable pre-attenuation: 0, 6, or 12 dB. Additionally, the mic has a selectable high-pass filter at either 80 or 160 Hz to eliminate low-noise and rumble. The LCT 550's front panel is illuminated, allowing you to easily select your pad and filter in dark environments. The microphone includes a black carrying case, shockmount, windshield, and artificial leather bag.
