Abstract:
1. A method for controlling parameters that modify an acoustic characteristic of a sound system to be set in an audio apparatus by performing remote control by using a remote control signal transmitter wherein said audio apparatus comprises a volatile memory storing first settings of a plurality of first parameters that modify the acoustic characteristic of the sound system, a non-volatile memory storing second settings of a plurality of second parameters that modify the acoustic characteristic of the sound system said first settings and second settings including setting of parameters for controlling switching of input of said audio system, a controlled section operating in accordance with values of said first parameters of said first settings stored in the volatile memory, a signal reception section and a control section, said method comprising: a step of receiving a control signal transmitted by wireless transmittance from said remote control signal transmitter, wherein said remote control signal transmitter comprises a plurality of operators to which remote control codes which are different from each another are respectively allotted, and a transmitter which transmits, by wireless transmittance, a control signal which corresponds to a predetermined one of the remote control codes allotted to said operators by operating the operator of said predetermined remote control code; a step of analyzing, in said control section, contents of the code of the control signal received by said signal reception section; a step of storing said plurality of first parameters stored in said volatile memory when the control signal analyzed in said analyzing step indicates instruction for storing said first settings; and a step of reading out second settings of said plurality of second parameters from said non-volatile memory when the control signal analyzed in said analyzing step indicates instruction for renewal to said second settings, renewing said first settings of said plurality of first parameters stored in said volatile memory by said second settings of said plurality of second parameters, and modifying the acoustic characteristics of the sound system using the second parameters, whereby said controlled section operates in said accordance with values of said second settings of said plurality of second parameters which have been renewed in said volatile memory.
