Next, an operation of the vehicle-mounted audio system 1 according to the present embodiment will be described. FIG. 5 is a flowchart showing the processing operation of the microcomputer 39 relating to the sub-side mode setting processing of the main body device 11.
[0060]
The sub-side mode setting process shown in FIG. 5 is a process operation related to automatic setting of the sub-side source mode when the dual mode is set to ON or OFF in response to a key operation of the dual mode key 23A.
[0061]
In FIG. 5, the control unit 48 of the microcomputer 39 determines whether the dual mode is set to ON (step S11). When it is determined that the dual mode is set to ON, the source type determining unit 43 of the microcomputer 39 determines whether the source type of the currently set source mode is the external source 12 based on the memory content of the source type memory 38B. Is determined (step S12).
[0062]
When it is determined that the source type of the currently set source mode is the external source 12, the control unit 48 selects the source mode in the external source 12 that is currently set, that is, the main-side source whose dual mode is ON. Then, the mode selector 41 is controlled so that the sub selector 36 selects an arbitrary source mode in the internal source 31 (step S13). The arbitrary source mode in step S13 may be, for example, a sub-source mode relating to the internal source 31 stored in the last mode memory 38D.
[0063]
When selecting an arbitrary source mode in the internal source 31 in step S13, the control unit 48 controls the mode setting unit 42 to set the selected arbitrary source mode to ON (step S14). The processing operation ends.
[0064]
When it is determined in step S12 that the source type of the currently set source mode is not the external source 12, the control unit 48 selects the source mode in the internal source 31 as the main-side source in the dual mode ON. The mode selector 41 is controlled by the sub selector 36 to select an arbitrary source mode in the external source 12 (step S15), and the selected arbitrary source mode is set to ON. Move to step S14. Note that the arbitrary source mode in step S15 may be, for example, a sub-source mode related to the external source 12 stored in the last mode memory 38D.
[0065]
If it is determined in step S11 that the dual mode is not set to ON, it is determined that the dual mode is OFF, and the source selected by the main selector 33, that is, the same source as the set source mode is set. By controlling the mode selector 41 so that the sub-side selector 36 selects the mode (step S16), the processing operation is completed.
[0066]
According to the sub-side mode setting process shown in FIG. 5, for example, the external source 12 including a plurality of sound sources sharing a single main-side second input terminal 33B (sub-side second input terminal 36B), and individual The mode is determined based on the contents of a source type memory 38B for storing and managing a source type for each sound source such as the internal source 31 including a plurality of sound sources provided with a main-side first input terminal 33A (sub-side first input terminal 336A). The setting unit 42 determines whether or not the source type of the currently set source mode is the external source 12. If the source type is determined to be the external source 12, the external source 12 Since the selection of the source mode related to other sound sources in the external source 12 is prohibited, the sound signals of different sound sources in the external source 12 are mixed and output. State can be reliably prevented.
[0067]
Furthermore, according to the sub-side mode setting processing, different source modes within the same source type are not selected at the same time for the main-side source and the sub-side source. By doing so, the operability can be improved.
[0068]
FIG. 6 is a flowchart showing the processing operation of the microcomputer 39 relating to the source mode selection processing of the main unit 11.
[0069]
The source mode selection process shown in FIG. 6 is a process of selecting and setting an arbitrary source in the internal source 31 or the external source 12 as the main source or the sub source during the dual mode ON.
[0070]
In FIG. 6, the control unit 48 of the microcomputer 39 determines whether the main-side operation mode is being set (step S21).
[0071]
When it is determined that the main-side operation mode is being set, the source type determination unit 43 of the control unit 48 determines whether or not the source type of the currently set main-side source is the external source 12 (step S22).
[0072]

[0105]
If an arbitrary source mode is selected by the main-side selector 33, the control unit 48 determines whether or not there is a source mode that has been set in the sub-side source (step S72).
[0106]
When it is determined that the sub-source has the set source mode, the prohibition determination unit 45 of the control unit 48 determines whether or not the combination of the main-side source mode and the sub-side source mode exists in the prohibition memory 38E. A determination is made (step S73).
[0107]
When it is determined that the source mode is in the prohibition memory 38E, the control unit 48 prohibits the selection of an arbitrary source mode selected by the main-side selector 33 in step S71, and selects an arbitrary source mode not included in the prohibition combination in the prohibition memory 38E. By selecting the source mode (step S74), this processing operation ends. In step S74, an arbitrary source mode not included in the prohibited combination in the prohibited memory 38E is selected.

If an arbitrary source mode is selected by the sub-side selector 36 in step S75, the control unit 48 determines whether or not there is a set source mode in the main-side source (step S76).
[0110]
When it is determined that the set source mode exists in the main source, the prohibition determination unit 45 of the control unit 48 determines whether or not the combination of the main source mode and the sub-source mode is in the prohibition memory 38E. A determination is made (step S77).
[0111]
When it is determined that the source mode is in the prohibition memory 38E, the control unit 48 prohibits the selection of any source mode selected by the sub-side selector 33 in step S75, and selects any source not in the prohibition combination in the prohibition memory 38E. By selecting the mode (step S78), this processing operation ends.
