Lewitt Audio Introduces the LCT 540 Subzero Microphone

Lewitt Audio has introduced the new LCT 540 Subzero microphone, a large-diaphragm cardioid condenser microphone with an exceptionally low self-noise.

Lewitt said the LCT 540 Subzero has a self-noise of -7dB SPL, which is where it acquired its name, and a dynamic range of 132dB.

"The acoustic self-noise of 4 dB (A) is caused by random molecules bouncing against the diaphragm. But that's a cumulative value. If you look at self-noise across the full frequency spectrum, you'll see that the LCT 540 Subzero is all the way below the hearing threshold. It's literally better than your ears,” said Moritz Lochner, product manager.

“Describing something frequency-dependent in one single value is nowhere near detailed enough at this level of engineering. We even redesigned our self-noise measuring equipment especially for this microphone."

Lewitt said a limited number of LCT 540 Subzero microphones will be available within the next couple of weeks, with full production planned for January, 2018. A street price of well below $1,000 is expected, the company said.
