PROBLEM TO BE SOLVED: To simply connect a speaker to an object terminal by displaying a channel through which a test tone signal is received and an output channel to which the speaker is connected. SOLUTION: A microcomputer 8 receives a test tone signal of each channel in a memory, an image display signal or a test tone signal reproduced from a recording medium by a reproduction device 11 and speaker arrangement pattern information being part of image information and a speaker arrangement diagram is displayed on a display device 9. The microcomputer 8 controls an input signal processing section 7, selects the signal, gives the signal to each of amplifiers 2a-2f from decided channel terminals 7a-7f and then the received channel is displayed. An output of each amplifier 2 is consumed by a speaker 3 connecting to an output terminal 5 and depending on the increased supply power, it is displayed that the speaker 3 is connected to an output terminal of the amplifier 2. Thus, matching of display and at the input channel output terminal and direction of sound is confirmed. |
