“I have to conclude that the LCT 550 is a very capable all-rounder that delivers an honest yet musically satisfying sound in just about any recording situation you can imagine. It is extremely quiet, as the specifications imply, which means it can be used for demanding work where the sound sources are not necessarily very close to the microphone. I’m not sure that the advanced auto-attenuation feature is a necessity for most users, but it doesn’t hurt to have it. While this microphone has a professional price tag it is still very reasonably priced given its fine performance.” – Paul White, Sound On Sound
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 …)
