ABSTRACT:
A parameter display portion of an acoustic signal processing apparatus (mixer) according to the present invention displays a setting of a parameter (channel group setting parameter) by use of a plurality of light-emitting display elements (LED) La through Lc. While the acoustic signal processing apparatus is under operating conditions with a setting of the parameter being established through a setting operation of an operator (on-switch) Bt, the display elements La through Lc in the entire parameter-establishable range are kept in display action. The parameter display portion is controlled such that, during the display action, the display element [(2)=La, (3)=Lb, (4)=Lc] corresponding to the established setting is displayed in the first display mode, while the other display elements [(2)=Lb and Lc, (3)=La and Lc, (4)=La and Lb] excluded from the established setting being displayed in the second display mode. As a result, the present invention provides quick, reliable and easy perception of the currently setting-established part in the entire parameter-establishable range.
