The LCT 550 is the first and only large-diaphragm studio microphone ever to achieve 0 dB (A) self-noise*. 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!
* 0dB-A electronics only, 3 dB (A) according to IEC 60268-1 due to Brownian motion (in simple terms: the sound caused by the movement of air molecules ...)
