Players 2 A and 2 B 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 4 A, 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 4 B, one of a plurality of audio signals of different signal formats including the analog format and the digital format. If the player 2 A is selected as the input for the first output system, the AV amplifier 3 sends a command to the player 2 A instructing the player 2 A to output an audio signal in the IEEE 1394 format, automatically setting the output signal format of the player 2 A to be a format that can be reproduced through the first output system.
