<P>PROBLEM TO BE SOLVED: To provide a game machine allowing selection of power amplifiers with serious consideration of the aspect of a sound quality by expanding the selections of the power amplifier. <P>SOLUTION: The game machine includes: a sound synthesizer LSI82; digital analog conversion means 84a and 84b; and power amplifiers 85a and 85b. The sound synthesizer LSI82 synthesizes a digital signal on the basis of sound data for controlling the sound output mode of sound output means 17a to 17c, and outputs the synthesized digital signal by serial communication. The digital analog conversion means 84a and 84b convert to analog the digital signals output from the sound synthesizer LSI82 to generate analog signals and output the generated analog signals as sound signals. The power amplifiers 85a and 85b amplify the sound signals output from the digital analog conversion means 84a and 84b and output the results to the sound output means 17a to 17c. <P>COPYRIGHT: (C)2012,JPO&INPIT |
