When music is reproduced and outputted, an attribute information acquisition unit (270) acquires, from a music information supply unit (220), reproduction music attribute information of the music. The attribute information acquisition unit (270) transmits, to a management device (100), the reproduction music attribute information as designated attribute information. In the management device (100), when the designated attribute information has been received, a derivation unit (140) acquires, from tuning information (TUI) in a storage unit (120), setting octave band information, setting musical instrument appearance frequency information and setting L/R phase difference information that correspond to the designated attribute information. On the basis of these pieces of information, the derivation unit (140) generates update information of a sound quality tuning set value, update information of a speaker setting and update information of a signal processing setting, and transmits, to an acoustic device (200), these pieces of information as setting update information. In the acoustic device (200) which has received the setting update information, the contents of the setting update information are set in a tuning and setting unit (230).
