Zusammenfassung:Reference gain values Ga1, Gb1 and Gc1 are set for respective EQ points A, B and C of a plurality of frequency bands in EQ CURVE 1 currently set in an EQ module. In response to an operation of an operator, an intensity parameter value, which is a multiplier for the reference gain values Ga1, Gb1 and Gc1, is changed, so that the reference gain values Gal, Gb1 and Gel are changed in a collective fashion. In EQ CURVE 2 having been changed from EQ CURVE 1, the intensity parameter value exceeds "1 (100 %)" and actual gain values of the EQ points A', B' and C' of the frequency bands are Ga2, Gb2 and Gc2, so that EQ CURVE 2 assumes emphasized frequency characteristics.
