Abstract:
1. An amplifier apparatus connectable to a separate playing device and for transmitting a command to the separate playing device, the separate playing device having a normal mode and a menu mode, shifting from the normal mode to the menu mode in response to a first command and, after lapse of predetermined time by performing timer count since the shift to the menu mode, shifting to the normal mode, comprising: an input section that has a first key and a second key, and does not have a third key for transmitting a third command for controlling the menu mode of the separate playing device to the separate playing device; a mode setting section having a normal mode and a menu mode, shifting from the normal mode to the menu mode in response to an operation of the first key, and shifting from the menu mode to the normal mode after lapse of a predetermined time which is the same as a predetermined time set in the separate playing device for shifting from the menu mode to the normal mode by performing a timer count since the shift to the menu mode, thereby synchronizing the mode of the amplifier apparatus and the separate playing device; a command transmitting section for transmitting the first command to the separate playing device in response to an operation on the first key; and a mode determining section for determining a mode set in the mode setting section when the second key is operated, wherein when it is determined that the mode setting section is in the normal mode, the command transmitting section transmits a second command for controlling the normal mode of the separate playing device to the separate playing device and, when it is determined that the mode setting section is in the menu mode, the command transmitting section transmits the third command to the separate playing device.
