2. Description of the Related Art In recent years, in the field of audio, in a combination of a plurality of sound source devices and a reproduced signal amplifying device for inputting and amplifying the reproduced signals, the interlocking operation between the devices is performed and the power supply to each device is performed. On / off
Many devices have been developed which are configured so that they can be performed collectively. The input sound source initial setting method at the time of power-on in such an acoustic device has a configuration as shown in FIGS.

[0003] An example of an input sound source initial setting method of the above-described conventional audio device will be described below with reference to the drawings.

FIG. 3 shows components of an input sound source initial setting method of a conventional audio device. The sound device shown in FIG. 3 includes a plurality of sound source devices such as a CD player 8 and a tuner 12, and an amplifier 1 which is a reproduction signal amplifying device that inputs and amplifies the reproduction signals.

In the amplifier 1, reference numeral 2 denotes a sound source switching key 2a for selecting a sound source to be input to a reproduction signal amplifying device from a plurality of sound sources, and on / off of a power supply to the sound source device.

With the above configuration, control as shown in the flowchart of FIG. 4 has been performed. That is, in the figure, in step 1, it is determined whether or not the power switch 2b is turned on.
If n has not been set, the process returns to step 1 to enter a standby state. In step 2, the amplifier control unit 3 controls the power supply unit 6 to start supplying power to the CD player 8 and the tuner 12.

When power supply to each sound source device is started, the CD player 8 starts controlling the CD reproduction signal output unit 10 by the CD control unit 9 and starts displaying on the CD display unit 11. Similarly, in the tuner 12, the control of the TN reproduction signal output unit 14 is started by the tuner control unit 13 and the display on the TN display unit 11 is started.

In step 3, the storage state of the sound source storage unit 7 is checked to determine whether initialization is necessary. If necessary, the process proceeds to step 4, and if not, the process proceeds to step 5. In step 4, the sound source storage unit 4 is initialized to a CD. In step 5, the amplifier control unit 3 controls the input sound source switching unit 5 according to the information stored in the sound source storage unit 7 to set the input sound source. For example, if the tuner is stored in the sound source storage unit 7, the input sound source is switched to the tuner. In step 6, the input sound source display unit 4 displays the sound source set in step 5 in order to indicate the sound source. In step 7, it is determined whether or not the sound source switching key 2a has been pressed. If the key has been pressed, the process proceeds to step 8, and if not, the process proceeds to step 11. In step 8, the amplifier control unit 3 controls the input sound source switching unit 5 to switch the input sound source. In step 9, the display of the input sound source display section 4 is also switched in accordance with the sound source switched in step 8. In step 10, the amplifier control unit 3 changes the information stored in the sound source storage unit 7 to information indicating the switched sound source. In step 11, it is determined whether or not the power switch 2b has been turned off. If the power switch 2b has been turned off, the process ends. If not, the process returns to step 7 and repeats steps 7 to 11.

[0010]

In recent years, in a small component system, which is a field of audio, there is a trend toward further miniaturization, and a sound source device may be combined and configured as a sound source of an audio device. In such a case, according to the above-described conventional input sound source initialization method of the sound device, it is not possible to determine which sound source the combined sound source device may be set to when the power is turned on. Therefore, in order to perform the determination, a sound source storage unit is provided in the composite sound source device, and when the supply of power is started, which sound source is to be set is determined based on information stored in the sound source storage unit of the sound source device. However, even in this method, the time that the stored information in the sound source storage unit can be held after the power is turned off is finite, and if two holding circuits are provided, a difference occurs in the holding time due to variations in circuit conditions. A discrepancy between the set sound source of the reproduced signal amplifying device and the set sound source of the composite sound source device occurs due to a discrepancy between the storage states of the storage contents of the sound source storage unit of the reproduced signal amplifier device having the switching unit and the sound source storage unit of the composite sound source device. There was a problem that there was a possibility.

An input sound source that displays the type of sound source and an input sound that switches the input sound source according to instructions from the amplifier control unit, including a relay or semiconductor switching circuit. Comprising a switching unit, and a power supply unit for supplying power to each tone generator, the tone generator section is a composite source device at least two have been incorporated into one device of the plurality of sound sources, a plurality of reproduction signal becomes the sound source An output unit, a sound source display unit for displaying each reproduction state, and a sound source control unit for controlling the output state of the reproduction signal output unit and controlling the display on the display unit, and the audio device is turned on. Sometimes said
In accordance with the input sound source information amplifier control unit of the reproduction signal amplifier side is stored in the sound source storing section, to send the sound source information to the composite tone generator of the tone generator device side, the input sound source information
The composite sound source device that has received the information selects a sound source that matches the received information and activates the sound source.

[0013]

According to the present invention, when the power of the audio apparatus is turned off, the type of the input sound source is stored in the sound source storage unit, and when the power of the audio apparatus is turned on again, the reproduced signal amplifying apparatus stores the sound source storage. By setting the input sound source according to the type of sound source stored in the unit and transmitting the information stored in the sound source storage unit to the composite sound source device, the composite sound source device sets the sound source according to the information. Therefore, the set sound source of the reproduction signal amplifying device and the set sound source of the composite sound source device can always be matched.
