Players 2A and 2B are each capable of outputting data read from a disc such as a CD or an SACD in any of signal formats including an IEEE 1394 format, an analog format and a digital format. An AV amplifier 3 includes a first output system for selectively outputting, to a speaker system 4A, one of a plurality of audio signals of different signal formats including the IEEE 1394 format, the analog format and the digital format, and a second output system for selectively outputting, to a speaker system 4B, one of a plurality of audio signals of different signal formats including the analog format and the digital format. If the player 2A is selected as the input for the first output system, the AV amplifier 3 sends a command to the player 2A instructing the player 2A to output an audio signal in the IEEE 1394 format, automatically setting the output signal format of the player 2A to be a format that can be reproduced through the first output system.
