Abstract
PURPOSE:To effectively perform the recording and reproduction of multi channel which has not been obtained only two channels, by adding four speakers located in front of the normal stereo to the synthesizing signal from the speakers located left, right and back of listeners. CONSTITUTION:Four sets of speakers located in front of the listener are taken as L, LF, RF, R and the signal from the two channel signal transmission line of L, R is fed to the respective speaker. Further, to the L and R or speakers, minimum signals R, L are fed, and to LF speaker, the minimum signal LF' in the signal RF from the synthesized signals of L, R is fed, and to the speaker RF, the signal RF' minimum in the output of the synthesized signal LF is fed. Further, speakers are added at the left and right back of listener, and to them, the signal from L, R synthesis circuit by RM matrix system is fed, the reproduction level is made lowered than the four speakers in front to effectively perform multi-channel recording and reproduction.
