Lewitt Shock Mount LCT-40-SH Microphone Suspension

The Lewitt LCT-40-SH is a purpose-engineered shock mount designed to remove stand-borne mechanical vibration from the microphone signal path — the type of low-frequency noise that appears as a low-end smear or rumble on a waveform when foot traffic or HVAC couples into a mic stand. Its elastic suspension system decouples the microphone body from the stand mechanically, so vibrations that would otherwise travel up the stand and into the capsule are absorbed by the suspension rather than transmitted. For the LCT-450 and LCT-240, which are condenser microphones with the sensitivity to reveal these artifacts clearly, the LCT-40-SH is the correct mechanical foundation — particularly in live rooms without floating floors or in project studios where acoustic treatment doesn't extend to the stand mounts.

Construction is alloy steel and metal, providing the rigidity necessary to hold a microphone accurately in position without flex or drift during a session. The quick-acting screw thread closure allows the engineer or performer to seat or remove the microphone in seconds, without the multi-rotation process of conventional designs — a workflow detail that adds up meaningfully across a full tracking day. Thread compatibility covers both 3/8" and 5/8" standards natively, fitting essentially any standard boom arm or desk stand without a separate adapter. At 5.9 oz, the mount adds negligible mass to a boom configuration. For recording engineers tracking vocals, acoustic instruments, or any source where a clean noise floor and stable microphone positioning are session priorities, the LCT-40-SH is a straightforward, well-built solution to a specific and solvable problem.
