Abstract
The CPS (center point stereo) system of the present invention is directed to stereo sound reinforcement of live music, particularly with electronically-implemented instruments such as guitars and keyboards that provide a musical source signal at line level. A special CPS processor, converting regular left and right stereo signals to sum and difference signals, enables a center stage acoustic image to be created directly from a forward-directed loudspeaker unit driven from the sum signal and enables left and right spatialized stereo images to be created by recombination with a difference field received indirectly from a sideways-directed special dipole loudspeaker unit conveniently co-located with the forward-directed loudspeaker unit and driven from the difference signal. The CPS processor receives L and R input from the instrument or from an interposed FX (musical effects) or DSP (digital sound process) unit receiving mono or stereo input from the instrument. CPS market potential ranges from full CPS systems to unique add-on CPS processors and dipole loudspeaker units as system building blocks.
