Sound is Half the Picture

1 Cost-effective Technology for a Competitive Advantage Unlike most other professional audio applications, the challenge of cinema sound system design comes not from the acoustics of the exhibition space but from the program material itself: digitally mixed and encoded soundtracks. Today s soundtracks have a wider dynamic range, require higher fidelity, and their multiple-channel digital mixes require three different types of loudspeakers each optimized to its particular application. Main channel stage/screen loudspeakers must reproduce dialog, full range music and sound effects with equal power and clarity. Where surround channel loudspeakers once played only an ambient role, today they are asked to reproduce nearly as much information as the main channels. And subwoofers are pushed to the limits of human hearing with thunderous sound effects at sometimes earth-shaking volume levels. With Digital Cinema, the future requirements of the entire cinema sound system may be totally re-defined. Finally, all of these loudspeakers must be contained in cost effective systems capable of performing at or near peak output for 12 hours a day or more. Seven days a week. For years and years. In response to these demands, EAW has focused its total system engineering approach on the problems of cinema sound and has become a major supplier of cinema loudspeaker systems. By studying how a loudspeaker will be used, EAW Engineering has created a comprehensive line of cinema loudspeakers that are easy to install and use, offering cinema exhibitors cost-effective technology for a competitive advantage / 06.00

2 CINEMA S YSTEMS THREE-WAY SCREEN SYSTEMS C S C X The CSC923 full-range screen channel loudspeaker system brings 3-way design to the largest cinema exhibition spaces. This system provides extremely high output and must be powered by a minimum of three amplifier channels (triamplification). The CSC923 has been approved by the THX division of Lucasfilm, Ltd., for use in THXcertified theaters. The four component system includes 4x 15-in woofers in a push/pull configuration, one horn-loaded 10-in mid frequency cone and a horn-loaded 2-in exit high frequency compression driver. The CSC923 combines many of EAW s breakthrough technologies including a unique asymmetrical design mid/bass horn with EAW s patented VA 4 phase plug, push/pull low frequency technology and an asymmetrical high frequency horn. The push/pull configuration of the LF section reduces mechanically induced distortion at high output levels. To move air forward (away from the enclosure) half of the woofers push while the other half pull. The CSC923 s MF horn with VA 4 phase plug drastically reduces the horn-throat cancellation distortion that degrades the naturalness and intelligibility of dialog. By dividing the mid/high material between two horn-loaded subsystems, pattern control over the entire frequency range is enhanced. The HF element features a 2-in exit compression driver loaded with a two-dimensional asymmetric HF horn ensuring even distribution of HF information throughout the auditorium. The CSC923X contains an internal passive MF/HF crossover allowing for biamplified operation. C S C The CSC723 full-range screen channel loudspeaker system is a scaled-down version of the CSC923 for large cinema exhibition spaces.
