摘要： Provided is an audio system in which an audio signal to be heard can be automatically set to an appropriate volume or sound quality. The audio system is provided with: a mobile terminal device provided with a microphone unit that collects surrounding sound waves, and a transmission unit that, on the basis of the sound waves collected by the microphone unit, sets the volume or sound quality of an audio signal to be amplified by an audio device, and transmits the set audio signal volume or sound quality information to the audio device; and an audio device provided with an amplification unit that amplifies the audio signal, a control unit that adjusts the audio signal volume or sound quality by means of the amplifier, and a receiving unit that receives the audio signal volume or sound quality setting information from the mobile terminal device. The control unit controls the amplification unit so as to adjust the audio signal volume or sound quality on the basis of the audio signal volume or sound quality setting information received by the receiving unit.

摘要： [Problem] To improve the operability of a sound level operation performed with respect to a plurality of audio devices. [Solution] A control screen 25 is displayed, said control screen 25 comprising: channel faders 26-1 to 26-4 which individually accept sound volume level operations for wireless network compliant speakers 1-1 to 1-4; and a master fader 27 which accepts a sound volume level operation collectively for the wireless network compliant speakers 1-1 to 1-4. In the master fader 27, a minimum value end portion 271 is displayed in a position indicating a scale value that is the same as the minimum value from among the scale values indicated by each of the channel faders 26-1 to 26-4, and a maximum value end portion 272 is displayed in a position indicating the scale value that is the same as the maximum value from among said scale values. The master fader 27 thus has a width W corresponding to the minimum value and the maximum value of said scale values.
