Our electro-optical unit (EOU) series provides regular analog signals for high performance recording, monitoring and analyzing equipment. We manufacture a complete range of single channel, dual channel and DSP-based models.
Each of our EOU units is designed to drive its designated OPTIMIC fiber optic microphones at consistent, peak performance.
EOU 400 Dual Channel Industrial
Dual channel EOU 400 supports monitoring up to two sensors simultaneously in industrial settings. It features two analog outputs; two pairs of ST-style fiber optic connectors; screw terminals for power input, test points and analog outputs; a green/red LED optical line condition indicator. This mountable unit has test points and trimmers to enable tuning for optimal sensor operation. Unit is powered by external DC power supply.
EOU 100 Single Channel
Our single channel EOU 100 is extremely compact. It features a pair of ST-style fiber optic connectors; a 3.5 mm socket for analog output; green LED voltage indicator. Unit is powered by external DC power supply.
EOU 200 Single Channel
Single channel EOU 200 has an enhanced electronics box. It features two analog outputs (one with volume control for headphones, another with fixed gain for monitor 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.
EOU 300 Dual Channel
Dual channel EOU 300 supports monitoring with two sensors simultaneously. It features two pairs of ST-style fiber optic connectors; two 3.5 mm stereo sockets (one for stereo analog output, another for headphones); dual volume control knobs; green/red LED voltage indicator. Unit is powered either by internal batteries or external DC power supply.
EOU 500 Real-Time Display
Single channel EOU 500, with liquid crystal display for real-time readout of data in industrial settings. It features one analog output; one pair of ST-style fiber optic connectors; screw terminals for power input, test points and analog outputs; a green/red LED optical line condition indicator. This mountable unit has test points and trimmers to enable tuning for optimal sensor operation. Unit is powered by external DC power supply.
EOU 2500 XLR Multi-Channel Rack-Mount
Ten channel EOU 2500, 19-inch rack-mountable for use with the OPTIMIC series, supports monitoring up to 10 sensors simultaneously. For each channel the unit features one analog (XLR) output connector, one pair of ST-style fiber optic connectors, a +20 dB gain toggle switch, test point and trimmer to enable channel-level sensor tuning for optimal operation. Unit is powered by internal AC/DC power supply.
EOU 250 Single Channel DSP
Single channel EOU 250 is based on EOU 200, adding a digital signal processer (DSP) for up to 22 dB of real-time ambient noise removal (three levels: low, mid, high).
EOU 275 Single Channel Flash Recorder
Single channel EOU 275 is based on EOU 250, adding a built-in 16-bit uncompressed SD Flash memory card recorder with sampling rate of 44.1 kHz.
EOU 350 Dual Channel DSP
Dual channel EOU 350 is based on EOU 300, adding a digital signal processer (DSP) for up to 22 dB of real-time ambient noise removal (three levels: low, mid, high).
EOU 375 Dual Channel Flash Recorder
Dual channel EOU 375 is based on EOU 350, adding a built-in 16-bit uncompressed SD Flash memory card recorder with sampling rate of 44.1 kHz.
