PURPOSE:To extract a well-balanced sound by branching an input of one electric sound signal inputted to an amplifier to two circuit lines for treble and bass, by separately amplifying the both and by making signals with the treble level and bass level adjusted in one. CONSTITUTION:An electric sound signal, supplied to input circuit 1, is diveded at branching point A into a treble component signal supplied to treble adjusting circuit 2 and a bass component signal supplied to bass adjusting circuit 3. In adjusting circuits 2 and 3, the levels of sound outputs are adjusted through the operations of resistances (a), (c) and (d) and capacitors (b) and (e). Then, the treble component signal and bass component signal adjusted separately are made into an electric sound signal with excellent frequency characteristics, which is outputted. |
