A sound system empllying 77 ceiling-mounted distributed loudspeakers has been installed in a 350-seat nightclub. The system provides directional realism by utilizing the precedence effect. Live sound sources are reinforced by -precedence loudspeakers- over the stage valance, while signals to overhead loudspeakers are appropriately delayed by an acoustical delay unit. Other features include variable electronic reverberation, slightly delayed monitor sound to performers for enhanced self-audibility, and approximately one kilowatt of available audio power.
