time, the group including the first channel and the second channel is released. When a plurality
of groups are created, the display color determiner 97 makes the display color different for each
group, and divides the display lights of the plurality of selection switches 922 to 926 into the
respective groups. The corresponding channel is lit. For example, when the first channel, the
second channel and the third channel are in the first group and the fifth channel and the sixth
channel are in the second group, the display of the second selection switch 922 The light and the
indicator light of the third selection switch 923 are lit in red, and the indicator light 926 of the

sixth selection switch is lit in blue. Next, the operation of the sound adjustment apparatus 900
according to the present embodiment will be described. First, the case where the first channel,
the second channel and the third channel are divided into a first group and the fifth channel and
the sixth channel are divided into a second group will be described. When the first selection
switch 921 is depressed for the first time and the fourth selection switch 924 is depressed for
the second time, the number of depressions is first counted by the counter 73, and then the
grouping is performed. The first channel, the second channel, and the third channel are divided
into a first group by the memory 75, and then the second selection switch 922 is displayed by
the display color determiner 97 as shown in FIG. And the indicator light of the third selection
switch 923 are turned on in a first color, for example, red, to indicate that the first channel, the
second channel and the third channel are divided into groups. Be When the fifth selection switch
925 is pressed for the third time and the seventh selection switch 927 is pressed for the fourth
time, the number of presses is first counted by the counter 73, and then the grouping unit The
fifth channel and the sixth channel are divided into the second group 75, and then the indicator
color of the sixth selection switch 926 is secondly displayed by the display color determiner 97
as shown in FIG. Lights up, for example, blue, to indicate that the fifth channel and the sixth
channel are divided into groups.
Next, the case of releasing the first group will be described. When any of the second selection
switch 922 and the third selection switch 923 lit in the first color continues to be pressed for a
predetermined time, the timer 74 first causes the second selection switch 922 to And the third
selection switch 923 is detected to continue being pressed for more than a predetermined period
of time, and then the first group is released by the group releaser 96, and then the display color
determiner 97 is selected. Thus, the indicator light of the second selection switch 922 and the
indicator light of the third selection switch 923 are extinguished, which indicates that the first
group has been released. As described above, the sound adjustment apparatus 900 according to
the fifth embodiment of the present invention makes plural channels into plural groups simply by
pressing the selection switch even when plural groups are created. It can be divided. Also, the
group can be released simply by pressing the selection switch corresponding to the channel
included in the created group for a certain period of time. In addition, since the indicator light is
integrally formed with the selection switch, it is possible to save space by the amount of
arrangement of the indicator light as compared to the case where the selection switch and the
indicator light are separately arranged. Furthermore, the selection switch and the indicator can
be confirmed from the same viewpoint. In the first to fifth embodiments described above, an
example has been described in which the adjustment operation device in the sound adjustment
apparatus of the present invention is configured by a fader that is adjusted by a slide operation.
It may be configured by an adjustable volume regulator or other adjustment operator. Moreover,
although the example which comprised the selection operation device in the sound adjustment
apparatus of this invention with the selection switch by which selection operation is carried out
by pressing operation was demonstrated, you may comprise by toggle switch other selection

operation devices. Further, the display in the acoustic adjustment device of the present invention
may be configured by a light emitting diode or any other display. In the first to fifth embodiments
described above, the acoustic signal conditioner of the present invention similarly cuts high
frequency components of acoustic signals of a plurality of channels included in the same group.
And although the example which applies a reverb was demonstrated, you may make it perform
adjustment of sound quality, and adjustment of volume other than that. As described above, the
present invention can provide a sound control apparatus that can be easily operated.
