- Optical fiber connection over extended lengths without signal loss
- Exceptionally low sensitivity to vibration
Fiber optic microphone for indoor and outdoor acoustic monitoring with extended frequency range response. Ideal for industrial use, placement in heavy machinery, or where the microphone requires very robust housing and fiber cables.
The SOM(5) Ext. freq. system comprises of an advanced fiber optic microphone & single-channel electro-optic unit (EOU200), for digital-to-analog conversion of optical microphone output signals. The Single Channel EOU 200 with enhanced electronics box. It features two analog outputs (one with volume control for headphones, another with fixed gain for monitoring equipment); one pair of ST-style fiber optic connectors; two 3.5 mm sockets (one for analog output, another for headphones); green/red LED voltage indicator. DSP model provides up to 22 dB of real-time ambient noise removal (three levels: low, mid, high). Unit is powered either by internal battery or external DC power supply.
