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!

  • 0 dB-A self-noise from electronics and circuitry
  • Highly precise calibration of the capsule and the electronics – any two microphones from this series, set identically, will always form a matched pair at +/- 0 dB
  • 1-inch dual system externally biased capsule with an active front and ultra-thin, gold-layered low mass diaphragm for superior transient response
  • Tailored frequency response for rich and authentic sound on stage or in the studio
  • Cardioid polar pattern for effective isolation of the main sound source
  • Noiseless push buttons for attenuation and HPF selection
  • Max SPL of 143 dB for an impressive total dynamic range of 140 dB
  • 3-position switchable pre-attenuation pad (0 dB, 6 dB, and 12 dB) for handling extremely high soundw pressure levels and 3-position high-pass filter
  • Illuminated user interface for quick and easy handling even in dark environments
  • Noiseless pushbuttons for quick and easy attenuation and HPF selection
  • Clipping history, automatic attenuation and key-lock provide error-free recording and unparalleled ease of use
    Gold-plated 3-pin XLR output connector
  • Immune to electromagnetic interference thanks to transformerless preamplifier circuitry
  • Extra-large hexagonal ruthenium-galvanized steel-mesh grille provides an open acoustic environment and prevents unwanted internal reflections
  • Comes in a black carrying case; includes LCT 40 SHx shock mount, LCT 40 Wx windshield and DTP 40 Lb artificial leather bag
