Quality sound reinforcement for the audience is critical for live broadcasts.  However, often the studio audience has to suffer with poor quality audio to ensure that the broadcast audio is not contaminated.  When Mr. Leno  complained that he was not getting enough energy from his audience an in depth study was conducted by the applicant using EASERA and 3D modeling.  The sound system was re-designed to include an array of Meyer MM4 in-between seat loudspeakers for speech reinforcement and re-configuration of the main Meyer Sound arrays for music reinforcement.  
One challenge of the space was the width of the set.  Timing issues of the live sound vs the sound from the distributed line arrays created the false impression of acoustical reflections.   A complex DSP system was programmed to allow 3 different timing scenarios each fed from a separate buss on the main console.  One delay chain times the line arrays back to the house band, the other to the guest band, and the third to the center stage. Additional delay chains are used to time the between seat speakers back to the center stage.  
The system has excellent speech intelligibility and musicality.  Audience response was improved and the house and guest bands are pleased with the preservation of their artistry through the sound system.
