Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an audio mixer device for mixing and outputting a plurality of audio frequency signals,
The present invention relates to a display device that displays the connection relationship of each unit that constitutes the mixer device.

[0002]

2. Description of the Related Art Some audio mixer devices have various units connected to each other 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, equalizer, delay device, etc. have. N1 and N2 are monitor channel units, which have a volume and the like. O1 to O8 are output connectors. Each of these units is arbitrarily connected according to the usage status, for example, as shown in FIG. As described above, this audio mixer device includes not only each unit but also an input connector and an output connector, and it is possible to connect the input connector and each unit, or connect the output connector and each unit. It is possible.

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

For example, FIG. 10 (a) 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. Cage,
Group channel unit G1 that is actually connected
The light emitting diode 1 corresponding to is emitting light. Similarly,
FIG. 10B shows a group channel unit G1 in which light emitting diodes 6 to 8 are provided and are actually connected in correspondence with the units that may be connected and the main channel units M1 to M3. LED 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, and 1
1a and 11b are delay device knobs.

However, in such an audio mixer device, since a large number of units are connected, double routing may occur. With double routing, for example, the 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 to the main channel unit M1 via the group channel unit G2. That is, the same signal is supplied to the same unit through different signal paths as described above.

When such double routing occurs, for example, in the case of the input channel unit C2 shown in FIG.
The input signal from the input connector T3 is reproduced abnormally greatly from the output connector O1, or the input terminal T3 due to the interference due to the characteristic difference between the group channel units G1 and G2.
The input signal from the output connector O1 is distorted from the output connector O1 and is reproduced. Therefore, it is found that double routing occurs somewhere.

In this case, first, the monitor channel unit N1 in 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, of the main channel units M1 and M2, the monitor channel unit M1 in which the light emitting diode corresponding to the monitor channel unit N1 emits light is searched for.

By repeating such operations in sequence, finally, it is found that the output signal of the input channel unit C2 is supplied to the main channel unit M1 through both the group channel units G1 and G2, and double routing occurs.

[0009]

However, in order to find out where double routing occurs due to such work, it is necessary to check the wiring while confirming which light emitting diode of each unit is emitting light. However, there is a problem that the work is very troublesome.

[0010]

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

Further, the retrieving means may display the re-retrieved unit in a state different from other retrieved units on the display means when re-retrieving the already retrieved unit.

[0012]

According to the present invention, when the unit which is predicted to be in the signal path in which the double routing occurs is designated by the designating unit, the searching unit retrieves the connection information in the storing unit and the designated unit. Find each unit present in the signal path extending from. Then, each unit found and the connection relationship between these units are displayed on the display means. Therefore, it is possible to find where the double routing occurs by looking at the connection relationship between the displayed units. Further, when the search unit searches again for a unit that has already been searched, that is, when double routing occurs, by displaying the re-searched unit in a state different from other searched units, You can easily find a unit with double routing.

EXAMPLE The first example has an audio mixer 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 processing device).

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

The storage means 28 is provided with two table-shaped storage areas 30 and 32 as shown in FIG.
The storage area 30 is arranged 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. A simple matrix is used to represent the connection relationship between each unit.

For example, when the input connector T1 and the input side of the input channel unit C1 are connected, a row corresponding to T1 (first row) and a column corresponding to C1 (17th column).
If a flag is set in the area of the intersection with and the input connector T3 is similarly connected to the input side of the input channel unit C2, the row (third row) corresponding to the input connector T3 and the row corresponding to C2 are corresponding. A flag is set in the area at the intersection with the row (18th row). 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, and the CPU 22 will be described later.
Is used when searching the storage area 30, and the keyboard 2
A flag is set in the flag area corresponding to the unit on the signal path of the signal output from the unit designated by 2 or on the signal path of the signal input to this unit.

When, for example, double routing occurs, the CPU 22 stores the unit existing in each signal path extending from the output side of the unit selected by the operation of the keyboard 26 as a base point in the storage area of the storage unit 28. The data of 30 is searched and detected, 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 in the flow chart shown in FIG. First, the storage area 32 is cleared (step S2), and it is determined whether any unit is 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.

When the determination in step S4 is YES, that is, when any unit is selected, the unit number (see FIG. 3) assigned to the selected unit is changed to C
The pointer N used for designating the unit of the row of the storage area 32 provided in the PU 22 is stored, the flag is set in the flag area of the storage area 30 corresponding to the unit designated by the pointer N, and further on the display device 24. To pointer N
The unit designated by is displayed (step S6). This selected unit becomes the base point of the search.

Then, it is determined whether or not the value of the pointer N is equal to 43 which is larger than the number 42 of all the units by 1, 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 designated by the pointer N in the memory area 32 (step S10). If this determination is yes, the value of the pointer I designating each column of the memory area 30 is set to 1 in order to start the search of the unit connected to the unit designated by the pointer N (step S12).

Next, it is judged whether the value of the pointer I is 43 which is 1 larger than the number 42 of all the units, that is, whether the columns of all the units are designated (step S14). If the determination is no, it is determined whether the flag is set in the Nth row and the Ith column of the memory area 30, that is, the unit of the Nth row and the unit of the Ith column are connected (step S16).

If this judgment is NO, the value of the pointer I is incremented by 1 (step S18), and step S14
Returning to step S14, 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, when the unit of the Nth row and the unit of the Ith column are connected, 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 designated by the pointer, the unit designated by the pointer I is displayed on the display device 24, and the unit designated by the pointer N previously displayed 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, the flag is similarly set in the flag area of the storage area 32 corresponding to the unit connected to this, and the display device 24 is displayed and is connected to the unit designated by the pointer N.

When the designation of all the units by the pointer I is completed (the answer in step S14 is NO), the value of the pointer N is increased by 1 (step S22), and steps S8 and thereafter are executed. Therefore, while the loop of steps S8, S10, and S22 is being executed, the value of the pointer N is incremented by 1, and each time the 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 designated by the pointer N is a unit connected to the previously searched unit, and if so, step S1
The loop of S2, S14, S16, S18, and S20 is executed to search the unit connected to this unit.

For example, as shown in FIG. 4, a keyboard 26
When the input connector T3 is specified by, the display device 24
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
Each unit existing in the signal path toward the output connector side having the base point and the connection relationship between them are displayed. Then, from this display, it becomes clear that the input channel unit C2 is double-routed via the group channel units G1 and G2.

A second embodiment is shown in FIGS. 5 and 6. First
In the second embodiment, each unit existing in the signal path extending from the designated unit as the base point to the output side is displayed as apparent from FIG. 4, but in the second embodiment, it is apparent from FIG. Each unit existing in the signal path extending from the designated unit to the input side 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 the row of storage area 32,
In the second embodiment, it is used to specify a column, and similarly, the pointer I is used to specify a column in the first embodiment, but in the second embodiment, it specifies a row. Used to In addition, in the first embodiment, steps S8 and S
16 and S22 are used, in the second embodiment, steps S8a, S16a and S22a are used.

In step S8a, it is determined whether the value of the pointer N is 0. In step S22a, the pointer N is determined.
The value of is decreased by one. These are for searching on the input side from the unit used as the base point.

In step S16a, the memory area 3
It is determined whether or not a flag is set in the area at 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 used as the base point to the input side.

As described above, when the main channel unit M1 is selected by the keyboard 26, as shown in FIG. 6, the main channel unit M1 is first displayed, then the group channel unit G1 is displayed, and then M1 is displayed. The group channel unit G2 is displayed next, the group channel unit G2 is displayed next, the group channel unit G3 is displayed next, the group channel unit G3 is displayed next, and the group channel unit G3 is displayed next. Hereinafter, similarly, each input connector T1, T3, T5, T7, T9, T1
Each unit existing in the signal path starting from the main channel unit M1 up to 0 and T11 is displayed, and the connection state between them is also displayed. As a result, the input channel unit C2 becomes the group channel unit G.
It is found that the double routing occurs by being connected to the main channel unit M1 via 1 and G2.

Incidentally, step S in both of the above-mentioned embodiments.
20 can be modified as shown in FIG. 7, for example. If double routing occurs, step S1
In 6 or S16a, the flag has already been set in the flag area of the storage area 32 corresponding to the unit (designated by the pointer I) determined to be connected to the previously searched unit.

Therefore, in step S22 following step S16 or S16a, it is determined whether or not a flag is set in the flag area of the memory area 32 corresponding to the unit designated by the pointer I.
In 24, the display of the unit designated by the pointer I is made different on the display device 24, and the unit designated by the pointer N is connected and displayed.

As a different display, as shown in FIG. 8, for example, if each unit is normally surrounded by a frame and the unit name is displayed in it, the frame is not displayed and only the unit name is displayed. It can be displayed. Also,
The frame and / or the unit name may be displayed blinking.

If the determination in step S22 is NO, that is, if it is not the double routing portion, the same processing as step S20 is performed and normal display is performed (step S26).

In the first embodiment, each unit in the signal path extending from the unit serving as the base point to the output side is displayed. In the second embodiment, the unit in the signal path extending from the unit serving as the base point to the input side is displayed. Is displayed, but both can be displayed at the same time.

[0040]

As described above, according to the present invention, since each unit in the signal path extending from the selected unit is displayed and the connection state between each unit is displayed, the double routing is performed. You can easily discover what is happening. Also, in order to display in this way, when searching the connection information of each unit, if the already searched unit is searched again, it is assumed that that unit is causing double routing, so this unit By replacing the display of with another, it is possible to more easily find the place where the double routing occurs.
