parameter. SOLUTION: DCA switches 22c, 23c, 24c and 31c are turned on, and input channels
CH2, CH3, CH4 and CH5 are set as allocation channels of DCA channel CH1. When the selection
switch 72 of the DCA channel CH1 is turned on and the display switch 71 is turned on, the
normal channel faders 22b, 23b, 24b, and 31b in the assigned channel reflect the adjustment
amount of the DCA fader 61b of the DCA channel CH1. The movement and the setting level
respectively set to the allocation channel are displayed. [Selected figure] Figure 2
Parameter display device
The present invention relates to a parameter display apparatus in an apparatus having an
adjustment means capable of adjusting parameters for each channel, and an adjustment means
capable of adjusting parameters of a plurality of channels collectively. And is suitable for
application to parameter display devices in analog mixers. Conventionally, the levels and
frequency characteristics of audio signals output from a large number of microphones or electric
and electronic musical instruments etc. are adjusted, mixed, and put together into several mixing
groups to be used as power amplifiers and various other devices. Mixers are known that feed into
recording equipment. The operator who operates the mixer adjusts the volume and timbre of
each audio signal of instrument sound and singing to the state considered to be most
representative of the performance by operating various panel controls on the mixing console.
ing. The mixer has a plurality of input channels as an input signal sequence, programs and mixes
the input signal sequence, and outputs the same to a plurality of output channels which are
output signal sequences. The signal of each input channel in the input signal sequence is
generally amplified by the head amplifier and output to the mixing processing unit. Then, the
frequency characteristic and the level are adjusted in the mixing processing unit, and mixing is

performed in the programmed combination. The output fader is then set to an arbitrary output
level and output to one of the output channels. [0003] In such a mixer, in the normal channel
consisting of the input channel and the output channel, a normal channel fader for adjusting the
level for each channel is provided. The normal channel faders in the input channels adjust the
delivery level of each input channel to the mixing bus, and the normal channel faders in the
output channel adjust the output levels of the mixing output. In addition, some mixers have a
DCA (Digitally Cntrolled Amplifier) channel. In this DCA channel, a plurality of normal channels
can be assigned to one DCA channel, and the level set by the DCA fader is added to the levels of
all the normal channels (assigned channels) assigned to the DCA channel I am trying to do it.
That is, the level of the assigned channel can be changed collectively. The position of the normal
channel fader represents the level adjusted by the normal channel fader for each channel.
Further, the position of the DCA fader represents a level (addition amount) to be commonly
added to the allocation channel. Then, the actual setting level for each channel is (normal channel
level + DCA level), and there is a problem that it can not be easily confirmed simply by looking at
the normal channel fader. Here, it is considered that the position of the channel fader is normally
set to a position reflecting the DCA level, but this causes the following problems. That is, in a
general fader, the set resolution of the level is mechanically finer near the initial position than at
the position far from the initial position. Then, if the position of the normal channel fader is a
position reflecting the DCA level, the position of the normal channel fader will often be located
far from the initial position, and level control should be performed at a position where the level
resolution is coarse. When it happens, it often happens. Therefore, the problem arises that it
becomes difficult to adjust the level finely and precisely. Therefore, it is an object of the present
invention to provide a parameter display device capable of easily confirming setting parameters
that are actually set, even if the parameters can be finely adjusted. A parameter display device
according to the present invention which can achieve the above object is a setting parameter of
an allocation channel set by the first parameter adjustment means and the second parameter
adjustment means. Since the instruction means for presenting the first parameter adjustment
means according to the present invention to the assignment channel is provided, it is possible to
easily confirm the set parameters actually set by operating the instruction means. Become. In this
case, since the setting state of the second parameter setting means is not reflected and presented
unless the instruction means is operated, the parameters can be set finely in the first parameter
setting means. Further, the setting state of the second parameter setting means may be reflected
and presented only for the selected one of the allocation channels, and the first parameter
adjustment means and the first parameter adjustment means may be operated when the
instruction means is operated. The movement of the parameter adjustment means 2 may be fixed
so that the parameters can not be adjusted.
Furthermore, when operating the instruction means, the setting parameter may be displayed on
10-04-2019

the display means for each channel provided in the vicinity of the first parameter adjustment
means, and the setting state of the second parameter setting means for each channel A switch
means may be provided to present the setting parameter reflecting. DETAILED DESCRIPTION OF

These normal channel faders 31b, 32b, 33b and 34b are vertically moved to adjust the level, and
the scale of the level is attached in the vertical direction. This scale is finely divided in the vicinity
of 0 dB, and the scale is roughened beyond that range. Furthermore, the display unit 40 is

assignment channel which is a normal channel assigned to the DCA channels CH1 and CH2 A
display (DISPLAY) switch 71 is provided to confirm the level set in. The normal channel means
each channel set in the first input channel unit 20, the second input channel unit 30, and the
output channel unit 50, and the allocation channel means that the DCA switch in the normal
channel is turned on. It means the channel that is being In the panel configuration shown in FIG.
2, since the DCA switches 22c, 23c, 24c and 31c are turned on and the pilot lamps are lit, the
input channels CH2, CH3, CH4 and CH5 are assigned channels. These assigned channels are
assigned to the turned-on DCA channel CH1 or DCA channel CH2 by turning on one of the
selection switches 61a and 62a before turning on the DCA switch. However, it is not possible to
assign input channels and output channels in a mixed manner in one DCA channel. Returning to
FIG. 1, the mixing apparatus 1 is provided with a communication interface (communication I / F)
13, and the mixing apparatus 1 can be connected to a LAN (local area network), the Internet, or a
communication network such as a telephone line. , And the external control device 200 can be
connected. As a result, the mixing operation of the mixing apparatus 1 can be performed from
the external control device 200 connected by the communication network. Also, the control
program and various data can be downloaded from the external control device 200. Each part of
the mixing apparatus 1 is connected to the communication bus 10a and has the same
configuration as a personal computer. Next, parameter display will be described below in the
mixing device 1 including the parameter display device according to the present invention. As
shown in FIG. 2, the DCA switches 22c, 23c, 24c and 31c are turned on in the state where the
selection switch 61a is turned on in the panel 2, and the input channels CH2, CH3, CH4 and CH5
are assigned channels of the DCA channel CH1. It is done.
In this case, in the assignment channel, it is possible to adjust the delivery level to the mixing bus
by moving the normal channel faders 22b, 23b, 24b and 31b provided for the respective
channels. Further, when the DCA fader 61b in the DCA channel CH1 is moved, the delivery level
to the mixing bus is adjusted in all channels of the assignment channel in the DCA channel CH1
consisting of the input channels CH2, CH3, CH4 and CH5 accordingly. Become so. As described
above, in the allocation channel, the level is set by the sum of the adjustment amount of the
normal channel fader in its own channel and the adjustment amount of the DCA fader in the
allocated DCA channel. However, since the adjustment amount of the DCA fader is not reflected
on the normal channel fader, even if the position of the knob on the normal channel fader is
checked, it is not possible to confirm the level set for that channel. Therefore, the selection switch
72 for selecting the DCA channel CH1 in the DCA display control unit 70 is turned on, and the
display switch 71 is turned on. Then, the position of the knob for the normal channel faders 22b,
23b, 24b, 31b in the allocation channel of the input channel CH2, CH3, CH4, CH5 is moved by
the adjustment amount of the DCA fader 61b of the DCA channel CH1. . This is performed by
adding the adjustment amount of the DCA fader 61 b held in the RAM 11 to the adjustment
amount of the normal channel fader in each allocation channel held in the RAM 11. As a result,
10-04-2019
5
the setting level set for each allocation channel can be confirmed by the position of the knob of
the normal channel faders 22b, 23b, 24b, 31b. After the normal channel faders 22b, 23b, 24b,
31b are moved, the positions of the normal channel faders 22b, 23b, 24b, 31b and the DCA fader
61b can not be moved so that the level can not be adjusted. Do. By the way, for the normal
channel which is not an allocated channel, it is possible to confirm the level set by the normal
channel fader in the channel. In addition, with regard to a normal channel which is not an
assigned channel even when the display switch 71 is turned on, the level can be adjusted by
freely moving the normal channel fader in the channel.
Here, although not shown in the panel 2, it is assumed that the selection switch 62 a in the DCA
channel unit 60 is turned on, and then the DCA switches 51 c and 54 c in the output channel unit
50 are turned on. Then, the output channels CH1 and CH4 are allocated to the DCA channel CH2
as allocation channels, and by operating the DCA fader 62b applied to the DCA channel CH2, the
output levels in the output channels CH1 and CH4 can be collectively adjusted. Become. When
the normal channel faders 51b and 54b are rotated, the output level of the output channel CH1
or the output channel CH4 can be adjusted. Then, when the selection switch 73 in the DCA
display control unit 70 is turned on and the display switch 71 is turned on, the positions of the
knobs of the normal channel faders 51b and 54b in the allocated channels of the output channels
CH1 and CH4 are the DCA channel CH2 The DCA fader 62b is rotated by the adjustment amount
of the DCA fader 62b. As a result, it becomes possible to confirm the setting level set for the
output channels CH1 and CH4 which are assigned channels, by the rotational position of the
knob of the normal channel faders 51b and 54b. After the normal channel faders 51b and 54b
are moved, the positions of the normal channel faders 51b and 54b and the DCA fader 62b are
fixed so as not to move. Next, FIG. 3 shows a flowchart showing the operation process of the DCA
fader in the parameter display device according to the present invention. Operation processing of
the DCA fader is started by interrupt processing of a predetermined cycle, and it is detected in
step S10 whether or not the DCA fader is operated. Here, if any one of the DCA faders is detected
in the detection circuit 14, the process proceeds to step S11, and the newly set DCA level is held
in the memory (RAM 11). Next, in step S12, the newly set DCA level is sent to the signal
processing circuit 18, and the signal processing circuit 18 reflects the newly set DCA level. This
reflection is performed by adding the newly set DCA level to the adjustment amount of the
normal channel fader of each normal channel in the allocation channel. At this time, the knob for
the DCA fader is at a position representing the set value of the DCA level.
When the process of step S12 is completed, and when it is not detected that the DCA fader is
operated in step S10, the process is returned to the main process described later. Next, FIG. 4
shows a flowchart showing the operation processing of the normal channel fader in the
parameter display device according to the present invention. The operation process of the
normal channel fader is started by the interrupt process of the predetermined cycle, and it is
10-04-2019
6
detected in step S20 whether or not the normal channel fader is operated. Here, if any one of the
normal channel faders is detected in the detection circuit 14, the process proceeds to step S21,
and the newly set normal channel level is held in the memory (RAM 11). Next, in step S22, the
newly set normal channel level is sent to the signal processing circuit 18, and the signal
processing circuit 18 reflects the newly set normal channel level. This reflection is performed by
replacing the adjustment amount of the normal channel fader with the newly set normal channel
level. At this time, the knob for the normal channel fader is usually at a position representing the
set value of the channel level. When the process of step S22 ends, and when it is not detected
that the normal channel fader is operated in step S20, the process returns to the main process
described later. Next, FIG. 5 shows a flowchart showing the main processing in the parameter
display device according to the present invention. When the power of the mixing device 1
including the parameter display device is turned on and the initial setting process is completed,
the main process is started. The DCA channel to be processed in this case is a DCA channel
corresponding to one of the selection switches 72 and 73 which are turned on. Then, in step S30,
it is detected whether or not the display switch 71 is operated to be turned on. Here, when the
detection circuit 14 detects that the display switch 71 is turned on, the process proceeds to step
S31, and the DCA level in the DCA channel to be processed is read from the memory (RAM 11) to
be processed. The position of the fader for the normal channel of the assigned channel (in the
example, all assigned channels assigned to the DCA channel to be processed) is obtained by
adding the DCA level to the position where the DCA level is reflected To the position that
represents the set level).
This is performed by adding the adjustment amount of the DCA fader held in the RAM 11 to the
adjustment amount of the normal channel fader in the allocation channel to be processed held in
the RAM 11. Next, in step S32, the normal channel fader of the assignment channel to be
processed and the DCA fader of the DCA channel to be processed are fixed so as not to be
operated. When the process of step S32 is completed and when it is not detected that the display
switch 71 is turned on in step S30, the process proceeds to step S33. In step S33, it is detected
whether or not the display switch 71 is operated to be turned off. Here, when the detection
circuit 14 detects that the display switch 71 is turned off, the process proceeds to step S34, and
the allocation channel to be processed (in the embodiment, all allocation channels allocated to
the DCA channel to be processed) In order to be able to operate the normal channel fader of (1)
and the DCA fader of the DCA channel to be processed, the fixing is released. Next, in step S35,
the respective normal channel levels, which are allocation channels to be processed, are read
from the memory (RAM 11), and the positions of the respective normal channel faders are moved
to the positions of the normal channel level. When the process of step S35 is completed and
when it is not detected that the display switch 71 is turned off in step S33, the process proceeds
to step S36. In step S36, other processes are executed in response to the instructions of the
various operators 15. Next, at step S37, it is detected whether or not stop of the main processing
has been instructed. Here, when it is detected that a stop of the main process is instructed, the
10-04-2019
7
main process ends, and when it is not detected that a stop of the main process is instructed, the
process returns to step S30, and the main process is executed again. In the parameter display
device according to the present invention described above, instead of presenting setting levels for
all allocation channels, a selection means is provided for selecting a part of the allocation
channels to the user, and the selection means The setting level may be presented only for the
assignment channel selected by the. Alternatively, a switch may be provided for presenting the
setting level to each of the normal channels, and it may be detected that the switch is turned on
to present the setting level for only the normal channel.
Furthermore, when the display switch 71 is turned on and presentation of the set level is
instructed, instead of fixing the fader for the normal channel so as not to move, the moved
amount is recorded as the normal channel level and displayed It may be made to reflect after the
switch 71 is turned off. Furthermore, the fader for the normal channel is moved to match the
setting level, and the value of the setting level is displayed on the display unit in the vicinity of
the fader for the normal channel for easy understanding. You may do so. This display part is the
display 21a, 22a, 23a, 24a, 31a, 32a, 33a, 34a, 51a, 52a, 53a, 54a in which channel numbers are
displayed in the configuration of the panel 2 shown in FIG. Furthermore, when the control
program is not stored in the ROM 12, the control program is stored in the hard disk or CD-ROM
and the control program is read into the RAM 11 to perform the same operation as the control
program is stored in the ROM 12. May be executed by the CPU 10. This makes it possible to
easily add or upgrade the control program. Furthermore, the communication I / F 13 may be
connected to a communication network such as a LAN, the Internet, or a telephone line, and may
be connected to the server computer via the communication I / F 13. In this case, when the
control program and various data are not stored in the ROM 12, the program and data may be
downloaded from the server computer and read into the RAM 11. Furthermore, in order to
present the setting level in an easy-to-understand manner for displaying the setting level, the
setting level (DCA) is displayed on the display section where the channel number is displayed as
shown in FIG. A function may be provided to simultaneously display the level + normal channel
level) and the normal channel level adjusted only by the normal channel fader. At this time, it is
preferable to make the color and the density of characters (values) of the setting level to be
displayed and the normal channel level different. The display of the setting level may be always
displayed or may be temporarily displayed only while the display switch is pressed, and may be
auxiliary information for confirming the setting level. Although the digital mixing device to which
the parameter display device according to the present invention is applied has been described
above, the parameter display device according to the present invention can also be applied to an
analog mixing device.
When the parameter display device according to the present invention is applied to an analog
mixing device, the distance moved from the reference position of the DCA fader is detected when
10-04-2019
8
the display switch 71 is turned on without using the memory for storing the DCA level. Thus, the
detected amount according to the movement distance is treated as the DCA level. In the above
description, although the parameter is described as a level, it is not limited to the level, and may
be another parameter related to mixing, and the present invention is not limited to a mixing
apparatus, and an adjustment means capable of adjusting the parameter for each channel. The
present invention can be applied to an apparatus having a plurality of channels, and parameters
capable of being collectively adjusted. As described above, according to the present invention, the
setting parameter of the allocation channel set by the first parameter adjustment means and the
second parameter adjustment means is the first parameter adjustment of the allocation channel.
Since the instruction means to be presented is provided in the means, it is possible to easily
confirm the setting parameters actually set by operating the instruction means. In this case, since
the setting state of the second parameter setting means is not reflected and presented unless the
instruction means is operated, the parameters can be set finely in the first parameter setting
means. Further, the setting state of the second parameter setting means may be reflected and
presented only for the selected one of the allocation channels, and the first parameter adjustment
means and the first parameter adjustment means may be operated when the instruction means is
operated. The movement of the parameter adjustment means 2 may be fixed so that the
parameters can not be adjusted. Furthermore, when operating the instruction means, the setting
parameter may be displayed on the display means for each channel provided in the vicinity of the
first parameter adjustment means, and the setting state of the second parameter setting means
for each channel A switch means may be provided to present the setting parameter reflecting.
