| Zusammenfassung: | A method and apparatus for automatically determining a characteristic of a speaker and automatically setting a speaker mode in an audio/video system. The method includes: detecting a current for operating the speaker by inputting a predetermined signal; measuring an impedance characteristic of the speaker in accordance with a frequency change based on the detected current; determining a speaker type based on the measured impedance characteristic; and setting a speaker mode based on an impedance characteristic curve of the discriminated speaker type. |
