The Stereo Fiber Optic Stethoscope enables you to listen and record through concrete walls, windows, and doors without the need to be inside the room. The FOS is ideal for permanent installations in structures and walls, due to its light weight and waterproof design.

The FOS Stereo system is comprised of two advanced fber optic contact microphones and dual-channel electro-optic unit (EOU300), for digital-to-analog conversion of optical microphone output signals.
The Dual Channel EOU300 supports monitoring with two sensors simultaneously. It features two pairs of ST-style fber optic connectors; two 3.5mm stereo sockets (one for stereo analog output, another for headphones); dual volume control knobs; green/red LED voltage indicator.
