LCT 540

Reference class condenser microphone

The LCT 540’s cardioid 1" 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 540 features three levels of attenuation and three switchable low-cut filters.
