Abstract
A system for reproducing stereophonic signals to create a stereophonic sound image in front of each of listeners sitting side by side in a compartment. The system includes a right-hand loudspeaker positioned relative to the right of the first listener sitting on the right, a left-hand loudspeaker positioned relative to the left of the second listener sitting on the left, and a center loudspeaker positioned between the right- and left-hand loudspeakers. A signal generator generates R and L stereophonic signals. The R signal is applied to drive the right- and left-hand loudspeakers. The L signal is fed to drive the center loudspeaker. The signal generator includes a circuit for attenuating the R signal to the right-hand loudspeaker and a circuit for attenuating the R signal to the left-hand loudspeaker.
