The present invention relates to a power amplifying apparatus which has a multi-amplifying function. The power amplifying apparatus is provided to: output optimal quality by automatically controlling the output of amplifying units by using a level difference between a plus signal and a minus signal; reinforce the sound quality output of a lower sound range by connecting and arranging multiple amplifying units; and have the multi-amplifying function which controls the reinforcement of an output change which is caused by a temperature difference by sensing a surrounding temperature. If the present invention is applied, the optimal sound quality is realized by automatically controlling the output level of a system controller in response to the level difference between the plus signal and the minus signal which are applied to the input terminal of a speaker and controlling the output level in response to the surrounding temperature at the same time. |
