FL-330 High-Sensitivity Wall Contact Microphone

The FL-330 is a premium high-sensitivity wall contact microphone engineered for professional vibration-based audio pickup through solid surfaces such as walls, floors, pipes, and structural materials. Featuring Sun Mechatronics’ innovative pin-less dual flat contact mic, the FL-330 offers enhanced durability and superior audio clarity without the fragility of traditional needle-type contact microphones.

Its dual-faced flat microphone design provides two listening modes: a regular side for capturing a broad frequency range with rich detail, and a reverse side optimized for clearer human voice pickup by emphasizing vocal frequencies and suppressing unwanted noise. The rugged needle-free construction eliminates the risk of pin breakage during positioning or sliding, making it ideal for repeated field use.

Built with a dedicated REC output tuned for IC recorders, the FL-330 allows direct connection to external recording devices for high-quality audio capture. Powered by a standard 9V battery with up to 50 hours of continuous operation, it delivers reliable long-duration performance in portable applications.
