PROBLEM TO BE SOLVED: To provide a smaller, power-saving, and low-noise multisource audio device which can automatically compensate and amplify only the ones requiring volume level compensation, according to the kinds of the audio signals of different volume levels supplied from a plurality of sound sources including DVDs, and also enables the user to optionally set the compensation properties. SOLUTION: The multisource audio device (MSA) reproduces a first voice signal (SNA1) having a first volume level, and a second voice signal (Sa1) having a small volume level (C) smaller by the first volume level than the first volume level. On the same volume level (O) compensating the specified level (Lc) concerned. In the device, a first voice signal (SNA2) and a second voice signal (Sa2) are attenuated severally by the attenuation properties(Ln and Lc) decided optionally so as to generate the third voice signal (SNA3) and the forth voice signal (Sa3) having the same volume levels.
