The first and only large-diaphragm studio microphone ever to attain 0 dB (A) self-noise*, Lewitt's LCT 550 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. Its 140 dB (A) dynamic range of guarantees the best-possible results – even in challenging environments. It has 3 pre-attenuation levels (0 dB, -6 dB and -12 dB) that increase maximum SPL to as high as 155 dB (A). It 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 2 high-pass filters: 80 Hz, 12 dB/octave and 160 Hz, 6 dB/octave. Manufacturing tolerances have been minimized thanks to highly precise calibration of the capsule and the electronics – meaning any 2 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 ...)

Ideal applications:

  • Classical instruments and ensembles
  • Ambitious stereo recording techniques (XY, ORTF, AB, etc.)
  • Vocals & background vocals
  • Acoustic instruments (strings, guitars, piano)
  • Overhead miking (drums & percussion)

Lewitt LCT 550 Includes:

  • LCT 550 microphone
  • LCT 40 SHx shock mount
  • LCT 40 Wx foam windscreen

  • Durable carry case

Lewitt LCT 550 Features:

  • Highly precise calibration of capsule and electronics—any 2 microphones from this series will always form a matched pair at +/- 0 dB
  • Precise transient response thanks to the 3-micron-thin, gold-layered, low-mass, 1" Mylar diaphragm
  • Extraordinary sensitive: capture even extremely weak signals with great precision and detail
  • Cardioid polar pattern for effective rear sound rejection
  • 0 dB (A) self-noise from electronics and circuitry *
  • 140 dB dynamic range Max. SPL of 155 dB (A)
  • Immune to electromagnetic interference thanks to transformerless preamplifier circuitry
  • Illuminated user interface for quick and easy handling in dark environments
  • Noiseless pushbuttons for attenuation and low-cut selection
  • Automatic Attenuation and Clipping History mode
