Abstract
An AV amplifier contains an input unit to input digital data and an operation unit that receives a reproduction instruction. A switching unit switches whether to output the digital data input to a server interface unit or DSP in response to the reproduction instruction. The DSP processes the digital data output to obtain and output a two-channel signal, which the server interface unit transmits by the switching unit to a server and receives an audio signal from the server. An audio reproduction unit reproduces the server interface unit received audio signal and an audio signal output by the DSP. An output unit outputs the reproduced audio signal to each speaker and a control unit controls the switching unit and the server interface unit in response to the reproduction instruction from the user. The control unit controls the switching unit, when two-channel audio reproduction is instructed from the user.
