Description
The MSC model FO-AM-02 is a versatile Audio Monitor that provides a means to monitor various audio sources in high electromagnetic fields or anechoic chambers and then listen remotely in a low field area. Signals sent over optical fiber are immune to interference or signal impairment that may be seen with wire cable. Major benefits provided are small size in a self-powered audio transmitter with electromagnetic immunity and extended battery life.
The audio transmitter is configured with two independent audio channels for selecting either unidirectional, omnidirectional or a low-noise microphone to suit a particular application. Standard microphone response is 20 Hz - 20 kHz with sensitivity to -35 dB. Four internally selectable gain jumpers provide amplification as needed.
The FO-AM-02 transmitter is EMI hardened and validated for EMC operation in harsh RF environments at power levels up to 200 V/m (46 dBV/m) from 500 kHz to 2 GHz. The FO-AM-02 system uses 820 nm wavelength multimode 62.5/125 µm, 100/140 µm or step-index 200 µm HCS fiber cables. SMA type 905 connectors are standard.
