Abstract

883,592. Stereophonic transmission systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 16, 1959 [April 17, 1958], No. 12187/58. Class 40 (4). In a stereophonic sound system of the type disclosed in Specification 787,528, wherein left and right-hand signals derived from respective microphones are reproduced by left and right-hand loud-speakers, respectively, and a combination of the signals is reproduced with delay by a central loud-speaker, the two microphones are disposed at substantially the same point with respect to the sound source so that the left and right-hand signals are substantially in phase. If desired, the low-frequency components of the combined signals fed to the central loud-speaker may be delayed to a greater extent than the high-frequency components thereof. Specification 781,186 also is referred to.
