PROBLEM TO BE SOLVED: To provide a signal processor capable of correctly determining a correspondence relation between a function and an input terminal about each source device, surely reducing the burden of a user related to connection work of the source device as a result, accordingly eliminating the occurrence of a connection error and a setting error in the conventional manner, or the like even when a plurality of source devices of the same kind that output the same kind of a signal are connected to reproduce the signal. SOLUTION: An AV amplifier 100 determines a correspondence relation between a source device preset by the user and a plurality of input terminals constituting an input terminal group 102A by making the user instruct whether an output from an output device is a desired one while making a SW 106A switch the plurality of input terminals constituting the input terminal group 102A by processing of a microcomputer 118, and stores the determined correspondence relation in a memory.
