Ample commercial power was available so the motor generators were not needed. Camera cables, microphone cables, talkback and PL lines, and coaxial cable feeds for stage monitors were run into the rear of the building. The theater had only been used for motion pictures and therefore had very poor lighting facilities. Scoops and spots were obtained to supplement the portable lighting equipment carried by the system.
