Abstract

PURPOSE:To give a sense of expansion by adding signals of middle and high-sound band components to channels of each other with opposite polarities and give a sense of reverberation by adding signals obtained by delaying high-sound band components of the same channel respectively. CONSTITUTION:Stereophonic signals L and R are inputted to input terminals 5L and 5R. Output signal R1-L1 passing through adder 6 and low-pass filter 8 which cuts off middle and high or more sound bands is inputted to adders 9R and 9L and is added to signals R and L to output signals R+R1-L1 and L+L1-R1. Next, signal R1-L1 passes through high-pass filter 10, which cuts off several hundreds hertz or less, and phase shifter 11 and are inputted to adders 12R and 12L, and signals R+R1+R2-L1-L2 and L+L1+L2-R1-R2 are outputted from adders 12R and 12L respectively and drive speakers 3R and 3L through power amplifiers 12R and 12L respectively.
