PURPOSE:To easily obtain a desired reproduction sound field space by sending control data for the use of setting a frequency characteristic separately to a front side equalizer means and a rear side equalizer means respectively. CONSTITUTION:An equalizer section is made up of a front side equalizer section 1F and a rear side equalizer section 1R and a frequency characteristic is independently adjusted for them by a control section 2. That is, in setting the frequency characteristics of the respective equalizers 1F, 1R when setting of the frequency characteristic is being adjusted at present, data during adjustment are stored in a RAM2 and when the setting is finished, a preset value is stored in a RAM1. When the control section 2 sends control data for the use of setting frequency characteristic to the equalizer sections 1F, 1R, the control section 2 discriminates whether or not the adjustment is in execution. As the result when the setting is finished, the control data are sent after the preset value in the RAM1 are transferred to the RAM2 and when the adjustment is still being made, the control data are sent as they are according to the setting value of the front side and the rear side from the RAM2. |
