摘要： An audio system may include a plurality of sound reproduction devices characterized by parameter values; a plurality of audio signal sources characterized by parameter values; a plurality of remote control devices, a system controller, constructed and arranged to wirelessly receive command signals from the remote control devices and to wirelessly transmit parameter values of audio signal sources and of sound reproduction sources to the remote control device. The remote control devices are constructed and arranged for wirelessly transmitting command signals to the system controller and for wirelessly receiving parameter values and displaying parameter values. The remote control devices are being further constructed and arranged to transmit command signals to and receive parameter values from a system controller that is separated from remote control. A remote control for use with the audio system illuminates only graphic figures corresponding to terminals to which a sound reproduction device is attached; illuminates graphic figures corresponding to surround speakers only if a selected sound reproduction device is equipped for surround speakers; and has a touch screen which can be disabled. An audio system has volume adjusting circuitry which allows collective volume adjusting of different devices while maintaining a volume offset, and has circuitry which allows collective turning on and off of sound reproduction devices receiving signals from the same signal source.
