Lewitt – LCT 140 AIR


Capture the source the way you want

Instrument condenser microphone with two switchable sound characteristics. Choose between an open and sparkling tone or a highly-realistic sound.

Designed for professional instrument recordings.

The LCT 140 AIR features a small diaphragm condenser capsule we’ve designed for professional instrument recording. Use the AIR and FLAT sound characteristics to record the source the way you want. Pre-attenuation pad and low-cut filter complete the package. With its superior transient response, the LCT 140 AIR provides high clarity for your recordings of guitar, drums, strings or other acoustic instruments. Its aluminum housing is robust and lightweight at the same time. The LCT 140 AIR has a cardioid characteristic and just sounds fantastic.

AIR and FLAT explained.

AIR delivers an open, sparkling character. A great choice if you need record ready sound right from the start. You can immediately use and share those recordings without spending any time on post-production.

FLAT provides a linear frequency response for “as-it-is” reproduction of drums, strings, acoustic guitars, and choirs. It’s a great choice if you aim for highly realistic sonic images.

Having both options at hand makes the LCT 140 AIR a highly versatile recording tool.
