A volume setting device for a surround audio device that variably sets the volume of a surround audio device, comprising: a reference oscillator provided in the device that outputs a reference frequency signal for test sound; and a reference oscillator provided in the device that outputs a reference frequency signal for a test sound; a switching unit that sequentially outputs the output to a speaker-side electronic volume; a microphone provided on the transmitter that collects the test sound based on the reference frequency signal from the front speakers and rear speakers; a transmitter that digitizes the volume level and transmits a volume level signal; and a detector that is provided in the device and that receives the volume level signal and detects the volume level of the test sound from the front speaker and the rear speaker, respectively. A volume setting device for a surround audio device, comprising: an adjustment section that is provided in the device and variably adjusts both the electronic volumes so that the difference between the two volume levels determined by the detection section becomes a reference value.
