The LCT 550 is the first and only large-diaphragm studio microphone ever to achieve 0 dB-A self-noise*, and thus the world’s quietest. That makes it possible to capture even extremely weak signals with great precision and detail.
 
The Austrian-developed LCT 550 sets new standards in terms of more than just self-noise. A dynamic range of 140 dB-A guarantees the best-possible results even in challenging settings. The three pre-attenuation levels (0 dB, -6 dB and -12 dB) increase maximum SPL to as high as 155 dB-A. The LCT 550 also offers a clipping history as well as an auto-attenuation mode that automatically switches to the next level of attenuation if the signal is too strong. For the elimination of structure-borne noise, there are two high-pass filters: 80Hz, 12dB/octave and 160Hz, 6dB/octave.
 
Manufacturing tolerances have been minimized thanks to highly precise calibration of the capsule and the electronics – which means that any two microphones from this series, set identically, will always form a matched pair at +/- 0 dB!
