A real studio workhorse.
 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.
