The LCT 540 Authentica exhibits a combination of qualities that will undoubtedly make it a studio favorite among audio engineers and professional musicians. Designed to complement modern recording techniques and meet the expectations of ever-demanding sound professionals, this versatile large-diaphragm condenser microphone offers outstanding performance in miking lead vocals, drums and percussion instruments, brass and woodwinds, classical music ensembles.
The LCT 540’s cardioid 1-inch capsule, enclosed by an extra-large hexagonal grille, captures elaborate, exceptionally nuanced sonic details and optimizes isolation of the main sound source by rendering off-axis sounds. The LCT features three levels of attenuation and three switchable high-pass filters, two-color LEDs as well as pushbuttons for noiseless handling. A dynamic range of 135 dB and an extremely low self-noise of 8 dB round off the features of this exceptional microphone.
Features and Applications
Features
1-inch dual-system externally biased capsule with an active front and ultra-thin, gold-layered low-mass diaphragm for superior transient responseTailored frequency response for rich and authentic sound onstage or in the studioCardioid polar pattern for effective isolation of the main sound sourceExtremely low self-noise of 8 dB and max SPL of 143 dB for an impressive total dynamic range of 135 dB providing a maximum of acoustic presence and clarity3-position switchable pre-attenuation pad (0 dB, 10 dB, and 20 dB) for handling extremely high sound pressure levels and 3-position high-pass filterIlluminated user interface for quick and easy handling even in dark environmentsNoiseless pushbuttons for quick and easy attenuation and HPF selectionClipping history, automatic attenuation and key-lock provide error-free recording and unparalleled ease of useRugged all-metal construction for reliable performance onstage and in the studioExtra-large hexagonal ruthenium-galvanized steel mesh grille provides an open acoustic environment and prevents unwanted internal reflectionsImmune to electromagnetic interference thanks to transformerless preamplifier circuitryCorrosion-resistant gold-plated 3-pin XLR output connectorComes in a black carrying case; includes LCT 40 SHx shock mount, LCT 40 Wx windshield and DTP 40 Lb artificial leather bag
