But the Austrian-developedLCT 550 sets new standards in terms of more than just self-noise.Its dynamic range of 140 dB (A) guarantees the best-possible results even in challenging settings.

Its three pre-attenuation levels (0 dB, -6 dB and -12 dB) increase maximum SPL to as high as 155 dB (A) but at the sametime, it's meant to be your tool of choice when it comes to recording the most fragile and quiet sound sourceswith great detail and dynamic range.

The LCT 550 also offers a clipping history as well as an auto-attenuationmode that automatically switches to the next level of attenuation if the signal is too strong.The LCT 550 is indeed a very versatile large-diaphragm microphone, and its excellent attributes stand out ina wide variety of applications.

Try it for capturing ambient sound, percussion instruments, ambitious vocal andchoral tracks, and even classical ensembles.


Features

  • 0 dB-A self-noise from electronics and circuitry*
  • A perfect match: highly precise calibration of the capsule and the electronics means that any two microphones from this series will always form a matched pair at +/- 0 dB
  • Precise transient response due to the 1-inch, ultra- thin, gold-layered low-mass diaphragm
  • Extraordinary sensitive: capture even extremely weak signals with great precision and detail
  • Maximum SPL of 143 dB (155 dB with 12 dB pad) for an impressive total dynamic range of 140 dB (!)
  • Immune to electromagnetic interference thanks to transformerless preamplifier circuitry
  • 3 switchable pads (0dB, -6dB, -12dB) for handling high sound pressure levels
  • 2 switchable low-cut filters: 80Hz (12dB/Oct), 160Hz (6dB/Oct )
  • Noiseless pushbuttons for attenuation and HPF selection
  • Cardioid polar pattern for effective sound rejection
  • Illuminated user interface for quick and easy handling in dark environments
  • Clipping history, automatic attenuation and key-lock make for error-free recording and unparalleled ease of use
  • Gold-plated 3-pin XLR output connector
