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
