The Lewitt LCT 940 Tube Microphone brings studio-legend versatility and tonal flexibility into one premium microphone by seamlessly blending a high-performance FET circuit with a classic 12AX7 tube stage.
The Lewitt LCT 940 Tube Microphone lets you dial in everything from transparent crisp detail to rich tube warmth - making it a true all-rounder for vocals, instruments, room ambience and more. With nine selectable polar patterns and a continuously variable “Amplification” blend control, you can tailor the mic’s character to the source and session. Switch or blend between FET and Tube architectures, select from Omni, Cardioid, Figure-8, Super-Cardioid, Wide Cardioid and four intermediate patterns, apply attenuation pads or high-pass filters — all via a dedicated remote power supply unit. This level of control makes the LCT 940 uniquely suited for pro studios, demanding sessions and engineers who want one mic to cover many sonic bases.
Lewitt LCT 940 Tube Microphone Features
- Hybrid design combining classic tube (12AX7) circuit with modern FET solid-state path - use either alone or blend them at any ratio.
- Nine polar patterns: Omni, Wide Cardioid, Cardioid, Super-Cardioid, Figure-8 + four intermediate patterns for flexible directional control.
- Remote power supply unit with illuminated interface: pattern selection, pre-attenuation pad (0 / –6 / –12 / –18 dB), selectable low-cut filters (Linear / 40 Hz / 150 Hz / 300 Hz) and clipping history.
- Massive sound-pressure-level handling: up to ~155 dB SPL (FET mode with attenuation) / ~152 dB SPL (Tube mode) depending on pad.
- Ultra-low self-noise: 8 dB(A) in FET mode, 12 dB(A) in tube mode — excellent for critical tracking.
