A seismic signal reception device on land comprising a large number of sensors each associated with an adjusting means which may be remote-controlled from a central control and recording station, by means of seismic data acquisition boxes distributed in the field. It is possible to rapidly change at any time, from the central station, the number of sensors forming each seismic trace, the weighting coefficients of the various elementary signals constituting a trace and to control pre-processing of the signals picked-up before their transmission to the recording laboratory. By modeling the features of the reception device, interpretation of the recordings may be highly simplified.
