Abstract:
1. A level adjustment apparatus including a plurality of operators each operable in both a level increasing direction and a level decreasing direction, individual ones of said operators having respective set values associated therewith, said level adjustment apparatus comprising: a grouping section that individually sets each of operators, selected from among said plurality of operators, to a forward or inverse operational direction, so that at least one operator is set in the forward operational direction and at least one operator is set to the inverse operational direction, and groups the selected operators into one or more groups; a level control section that, when any one of said operators in one of the groups is operated, controls each of the set values of the operators in the one group in accordance with an operated amount generated through operation of the operated operator in such a manner that the set value of the at least one operator set to the forward operational direction is controlled by adding the operated amount while the set value of the at least one operator set to the inverse operational direction is controlled by subtracting the operated amount, a grouped state display section that displays respective grouped states of said operators grouped by said grouping section; and an operational direction display section that displays respective operational directions of said operators set via said grouping section.
