The sloped portion 24 is also configured to have a rectangular planar shape, and two touch
displays 34 and 36 are provided along the long side direction. Operation key display portions
381 to 388 are displayed on the touch displays 34 and 36, respectively. The operation key
display portions 381 to 388 are vertically long, and they are displayed so as to be positioned on
extension lines in the longitudinal direction of the operation units 261 to 268, respectively.
[0012]
The operation key display unit 381 displays a switch unit for adjusting acoustic characteristics in
the same channel 1 as the operation unit 261. For example, as shown in FIG. 1B, an on switch
401 for operating the equalizer, an off switch 421 for stopping the operation of the equalizer, a
switch 441 for setting the cutoff frequency of the low pass filter to 20 Hz, A switch for setting to
60 Hz and a switch 461 for setting 100 Hz. These acoustic characteristics are, of course, for
adjusting acoustic characteristics different from the acoustic characteristics adjusted by the knob
provided in the operation unit 261 which is the same channel. By touching the display of each
switch with a finger, the function assigned to each switch operates.
[0013]
In FIG. 1B, EQ indicates that the on switch 401 and the off switch 421 relate to the equalizer, and
FC indicates that the switches 441, 461, and 481 relate to the cutoff frequency of the filter. It is a
display to show that it is a thing.
