Abstract

PURPOSE:To obtain excellent audio effect with natural feeling of echo, by reproducing the input signal with the main speakers after amplification and reproducing it with auxiliary speakers by delaying and amplifying it. CONSTITUTION:The signal from the input terminal 11 having the signal R of right channel and the signal L of left channel, is reproduced from the main speakers 15 via the first power amplifier 12 as it is on one hand, and reproduced from the auxiliary spealers 16 from the second power amplifier 14 after being delayed by time tau, at the dalay element 13 on the other hand. The listener can listen to the stereo sound having feeling of echo by left and right ears for the mixing tone of the reproduced sound from the main and auxiliary speakers 15 and 16. In other case, as the input to the delay element 13, the mixing signal of left and right both channels can be used.
