The Portable Field Recording System is a multi-channel device that will record, unattended, for 24 hours in a frequency band from dc to 313 Hz. The system can operate without preempting a patch panel terminal, because female connectors are pigtailed in parallel with each signal input cable jack. Prime power for the system can be furnished by either a 12-vdc source or a 115-vac, 60-cycle source. Author
