PROBLEM TO BE SOLVED: To easily change the ratio of the air volume at the same air outlet mode. SOLUTION: When an automatic amplifier 10 is operated in the self diagnostic mode, and a [fan] switch 56 is pressed, the regular setting of the ratio of the air volume to the preset air outlet mode can be changed to a special setting. For example, in the foot mode, the air of 10-30% is leaked from a deflector air outlet in the regular setting and the ratio of the air volume that the remaining air is supplied from the foot air outlet is set, and this setting can be changed to a special setting that the air of 100% is supplied from the foot air outlet by pressing the [fan] switch 56.
