Input/Output's MSX™ fiber optic telemetry multi streamer system provides superior data collection with one of the widest frequency bandwidths in the industry.
The system are supporting 16 streamers and 7,680 channels.
Advanced user-interface design with a hands-off approach increases efficiency and automation by providing quick and easy monitoring as well as quality-controlling of all in-water equipment. Hardware and software designed for one-man operation. This "single look" concept provides instantaneous detection of errors and superior Quality Control.

Comprehensive set of Quality Control including:
- Real-time data-snooping;
- System Event and Header checks;
- Monitoring of chassis' health;
– Seismic, QC displays;
- Acceptance tests.
