The invention relates to a signal processing system comprising a signal processing device (8) and a portable information carrier (2). The signal processing device comprises a signal source selection device (11), having a number of preset positions. A preset position can be related to a signal source and a number of parameter values. With the aid of read means (1), write means (14) and the portable information carrier the preselection settings can be exchanged between similar signal-processing devices. In a first memory section (4) the signal source names are related to specific data, such as a frequency or channel number. In a second memory section (5) and in a memory of the portable information carrier preset positions are related to the parameter values and to signal source names, which uniquely identify the signal sources within a given set of signal sources.
