SOUND BALANCE AUTOMATIC ADJUSTMENT DEVICE

摘要

PURPOSE:To provide the sound balance automatic adjustment device which automatically detects a melody signal. CONSTITUTION:Plural resistances 28 are connected in series between a 1st channel input 24 where an accompaniment is inputted and a 2nd channel input 26 where the accompaniment and a song are inputted. A minimum output detecting means 30 detects the smallest output among signal outputs taken out of the connection points of the respective resistances. A switching means 32 connects only the connection point of the resistance 28 for the smallest output detected by the minimum output detecting means 30 to an output terminal 36. Consequently, the accompaniment of both the channels can be removed and only the song (melody signal) can automatically be detected.
