Abstract

PURPOSE:To orientate the acoustic image in an arbitrary direction around the listener by reproducing of two speakers, by operating four outputs of four-channels panning-potentiometer. CONSTITUTION:Outputs O1-O4 and O1'-O4' obtained from four-channels panning-potentiometers 1 and 1' are supplied to audio mixer 7, and outputs O1 and O1', outputs O2 and O2', outputs O3 and O3', and outputs O4 and O4' are mixed, respectively, to obtain mixed outputs at output terminals M1-M4. Outputs M1 and M2 are applied to mixer 10 of 6-channels input and 2-channels output. Outputs M3 and M4 are supplied to mixer 10 through longitudinal position deciding circuits 8 and 8' and circuits 9 and 9' for generating the difference between both ears. An imaginary sound source is orientated in the left 90 deg. direction of listener 5 by circuits 8 and 9, and another imaginary sound source is orientated in the right 90 deg. direction of listener 5 by circuits 8' and 9'. Two outputs of mixer 10 are amplified by amplifier 3 and are applied to speakers 4 and 4'. As a result, the acoustic image is orientated at an arbitrary point within the range of left 90 deg. to right 90 deg. in front of listener 5 by adjusting the panning-potentiometers.
