DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio mixer for mixing and outputting a plurality of audio frequency signals.
The present invention relates to a display device for displaying a connection relation between units constituting the mixer device.

[0002]

2. Description of the Related Art Some audio mixer devices connect various units, for example, as shown in FIG. In FIG. 9, T1 to T16 are input connectors, C1 to C8 are input channel units, G1 to G5 are group channel units, M1 to M3 are main channel units, and each of these units is a volume, an equalizer, a delay device, and the like. have. N1 and N2 are monitor channel units having a volume and the like. O1 to O8 are output connectors. These units are arbitrarily connected according to the use situation, for example, as shown in FIG. As described above, the audio mixer device includes not only each unit but also an input connector and an output connector, and can connect the input connector to each unit or connect the output connector to each unit. You can do it.

In order to indicate to which unit the output signal is supplied from each of the units connected in this way, each unit is provided with a light emitting element corresponding to each of the units which may be connected. A light emitting element such as a diode is provided, and the light emitting diode corresponding to the actually connected unit emits light.

For example, FIG. 10A shows an input channel unit C1, in which light emitting diodes 1 to 5 are provided corresponding to units which may be connected, group channel units G1 to G5. Yes,
Group channel unit G1 actually connected
Are emitting light. Similarly,
FIG. 10 (b) shows a group channel unit G1, in which light emitting diodes 6 to 8 are provided corresponding to the main channel units M1 to M3 which may be connected, and actually connected. Light emitting diode 6 corresponding to the main channel unit M1
Is emitting light. In both figures, 9a and 9b are volume knobs, 10a and 10b are equalizer knobs, 1
1a and 11b are delay device knobs.

However, in such an audio mixer device, since many units are connected, double routing may occur. Double routing means that, for example, an output signal from the input channel unit C2 in FIG. 9 is supplied to the main channel unit M1 via the group channel unit G1 and also supplied to the main channel unit M1 via the group channel unit G2. As described above, the same signal is supplied to the same unit via different signal paths.

When such double routing occurs, for example, in the case of the input channel unit C2 in FIG.
An input signal from the input connector T3 is reproduced abnormally large from the output connector O1, or the input terminal T3 due to interference due to a characteristic difference between the group channel units G1 and G2.
Is detected from the output connector O1 as distorting the input signal from the output connector O1, and it is found that double routing has occurred somewhere.

In this case, first, the monitor channel unit N1 from which the light emitting diode corresponding to the output connector O1 emits light is searched for among the monitor channel units N1 and N2. Further, the monitor channel unit M1 in which the light emitting diode corresponding to the monitor channel unit N1 emits light is searched for from the main channel units M1 and M2.

[0008] Such operations are sequentially repeated, and finally, the output signal of the input channel unit C2 is supplied to the main channel unit M1 via both the group channel units G1 and G2, and it is found that double routing has occurred.

[0009]

However, when searching for a place where double routing has occurred due to such an operation, it is necessary to check the connection while checking which light emitting diode of each unit is emitting light. And the operation is very troublesome.

[0010]

In order to solve the above-mentioned problems, the present invention provides a storage means for storing connection information between a plurality of units constituting an audio mixer device, Designating means for designating an arbitrary one of them, a search means for searching each unit existing in a signal path extending from the unit specified by the designating means from the connection information of the storage means, Display means for displaying a connection relationship between these units.

[0011] In addition, when the already searched unit is searched again, the search means displays the researched unit in a state different from other searched units on the display means.

[0012]

According to the present invention, when a unit predicted to be in the signal path where double routing occurs is specified by the specifying unit, the search unit searches the connection information in the storage unit, and specifies the specified unit. To find each unit present in the signal path extending from. Then, the display unit displays each of the found units and the connection relationship between these units. Therefore, by looking at the displayed connection relationship between the units, it is possible to find out where double routing has occurred. Further, when the search means has searched for the already searched unit again, that is, when double routing has occurred, by displaying the re-searched unit on the display means differently from other searched units, You can easily find the unit where double routing has occurred.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment has an audio mixer main body 20, as shown in FIG. The audio mixer body 20 includes, for example, input connectors T1 to T16 and input channel units C1 to C as shown in FIG.
8, group channel units G1 to G5, main channel units M1 to M3, monitor channel units N1 and N2, and output connectors O1 to O8. The audio mixer body 20
Can be configured by a DSP (Digital Signal Processor).

In addition to the audio mixer body 20,
A CPU 22 is provided.
A display device 24 configured by an RT or the like is provided. The CPU 22 includes a keyboard 26 and a RAM.
The storage means 28 is also provided.

The storage means 28 is provided with two storage areas 30 and 32 in the form of a table as shown in FIG.
The storage area 30 is configured in a matrix having rows corresponding to the output side of each unit (including input and output connectors; the same applies hereinafter) and columns corresponding to the input side of each unit. The connection relationship between each unit is represented using a simple matrix.

For example, when the input connector T1 is connected to the input side of the input channel unit C1, a row corresponding to T1 (first row) and a column corresponding to C1 (17th column).
A flag is set in the area of the intersection with, and similarly, when the input connector T3 is connected to the input side of the input channel unit C2, the row corresponding to the input connector T3 (third row) and the row corresponding to C2 are connected. A flag is set in the area of the intersection with the column (the 18th column). Similarly, the connection relation of each unit is stored in the storage area 30.

The storage area 32 has a flag area corresponding to each unit.
Is used to search the storage area 30, and the keyboard 2
A flag is set on the signal path of the signal output from the unit designated by 2 or on the flag area corresponding to the unit on the signal path of the signal input to this unit.

For example, when double routing occurs, the CPU 22 stores the units existing in each signal path extending from the output side of the unit selected by operating the keyboard 26 in the storage area of the storage unit 28. The data of 30 are searched and detected, and the detection result is displayed on the display device 24, and the connection relation between the displayed units is also displayed on the display device 24.

Therefore, the CPU 22 operates as shown in the flowchart of FIG. First, the storage area 32 is cleared (step S2), and it is determined whether any unit has been designated by the keyboard (step S2).
4). If not specified (if the determination in step S4 is no), step S4 is repeated until the determination becomes yes.

If the determination in step S4 is YES, that is, if any unit is selected, the unit number (see FIG. 3) assigned to the selected unit is changed to C
The data is stored in a pointer N used to specify a unit in a row of a storage area 32 provided in the PU 22, a flag is set in a flag area of a storage area 30 corresponding to the unit specified by the pointer N, and Pointer N
Is displayed (step S6). The selected unit becomes a search base.

Then, it is determined whether or not the value of the pointer N is equal to 43 which is greater than the number 42 of all the units by one, that is, it is determined whether or not all the units are designated by the pointer N (step S8). If the determination in step S8 is yes, this process ends.

If the determination in step S8 is NO, it is determined whether a flag is set in the flag area specified by the pointer N in the memory area 32 (step S10). If this determination is YES, the value of the pointer I that specifies each column of the memory area 30 is set to 1 in order to start searching for a unit connected to the unit specified by the pointer N (step S12).

Next, it is determined whether or not the value of the pointer I is 43 which is one greater than the number 42 of all units, that is, whether or not a column of all units has been designated (step S14). If this determination is NO, it is determined whether a flag is set in row N and column I of the memory area 30, that is, whether the unit in row N and the unit in column I are connected (step S16).

If the determination is no, the value of the pointer I is increased by 1 (step S18), and the value of the pointer I is increased in step S14.
Then, steps S14, S16, and S18 are repeated until the determination in step S16 becomes yes.

If the determination in step S16 is yes,
That is, if the unit in the N-th row is connected to the unit in the I-th column, the pointer I in the memory area 32 indicates that the unit designated by the pointer I is connected to the previously designated unit. A flag is set in the flag area corresponding to the unit specified by, the unit specified by the pointer I is displayed on the display device 24, and the unit specified by the pointer N displayed earlier is connected and displayed (step S20).

Then, step S18 and subsequent steps are executed.
Therefore, if there is another unit connected to the unit designated by the pointer N, a flag is similarly set in the flag area of the storage area 32 corresponding to the unit connected thereto, and 24 and is connected to the unit specified by the pointer N.

When the designation of all the units by the pointer I ends (when the answer to the step S14 is NO), the value of the pointer N is increased by 1 (step S22), and the steps from step S8 are executed. Therefore, while the loop of steps S8, S10, and S22 is being executed, the value of the pointer N is incremented by one, and each time a flag is set in the flag area in the storage area 32 designated by the pointer N, That is, it is determined whether the unit specified by the pointer N is a unit connected to the previously searched unit, and if so, the process proceeds to step S1.
The loop of 2, S14, S16, S18, and S20 is executed to search for a unit connected to this unit.

For example, as shown in FIG.
When the input connector T3 is designated by the
First, the input connector T3 is displayed, then the input channel unit C2 is displayed, and T3 and C2 are connected and displayed. Next, the group channel unit G1 is displayed, and G1 and C2 are connected and displayed. Then, the group channel unit G2 is displayed, and G2 and C2 are connected and displayed.

Next, the main channel unit M1 is displayed, and G1 and M1 are connected and displayed. Then, the main channel unit M1 is displayed again, and G2 and M1 are connected and displayed. Hereinafter, similarly, the input connector T3
Are displayed, and the respective units existing in the signal path toward the output connector side with respect to are connected and their connection relations are displayed. Then, it becomes clear from this display that the input channel unit C2 is double-routed through the group channel units G1 and G2.

FIGS. 5 and 6 show a second embodiment. First
In the embodiment, as shown in FIG. 4, each unit existing in the signal path extending from the designated unit as a base point to the output side is displayed. In the second embodiment, the units are clearly shown in FIG. Each of the units present in the signal path extending from the designated unit to the input side from the designated unit is displayed. In FIG. 6, the main channel unit M1 is used as a base point.

Therefore, in the first embodiment, the pointer N
Was used to specify a row in the storage area 32,
In the second embodiment, the pointer is used to designate a column. Similarly, in the first embodiment, the pointer I is used to designate a column. In the second embodiment, a pointer is designated. Used to In the first embodiment, steps S8, S8
In the second embodiment, steps S8a, S16a, and S22a are used, whereas steps S22 and S22 are used.

In step S8a, it is determined whether the value of the pointer N is 0.
Is decreased by one. These are for searching for the input side from the base unit.

In step S16a, the memory area 3
It is to determine whether or not a flag is set in the area of the intersection of the row designated by the pointer I of 0 and the column designated by the pointer N. This is also for searching from the unit serving as the base point to the input side.

As shown in FIG. 6, when the main channel unit M1 is selected by the keyboard 26 as shown in FIG. 6, the main channel unit M1 is displayed first, and then the group channel unit G1 is displayed. G1 is connected and displayed, then the group channel unit G2 is displayed, M1 and G2 are connected and displayed, then the group channel unit G3 is displayed, and M1 and G3 are connected and displayed. Hereinafter, similarly, each of the input connectors T1, T3, T5, T7, T9, T1
