The analogue signals are fed to an amplifier 2 whose gain is controlled by digital signals, from 3, recorded with the seismic signals, to restore compression applied to the signals before recording. The resulting signals are fed through an a.g.c. system to provide compression of the signals before demultiplexing and display on an oscillograph 11. The a.g.c. system comprises two variable gain amplifiers 13 and 14 whose gain is controlled by respective feedback circuits including amplifiers 26 or 27, comparator circuits 28 or 29, full wave rectifiers 30 or 31, and ripple filters 32 or 33, to provide slow acting a.g.c. which compresses the signals without destroying the amplitude relation between separate signals of the multiplexed set. The feedback in the case of the second amplifier 15 may be derived via switch 17 optionally direct from the amplifier output or from the average signal of the two outside channels and the middle channel of the demultiplexed signal fed to the oscillograph 11. The initial and final gains of the amplifiers can be set by applying further signals to the comparator circuits 28 and 29 from circuit 20 and in addition a time varying gain characteristic can be applied by a timing circuit 24 which, when switch 25 is closed cuts off amplifier 26 and 27 and changes the time constants of filters 32 and 33 so the gain increases exponentially with time.
