    Section 4 Description Overview Professional loudspeaker systems are designed to optimize spectral, spatial, temporal and usability performance attributes. Quite often optimization in one area compromises performance in another. Thus, loudspeaker design is the art of balancing these goals while minimizing compromise. In order to achieve these goals for the KF700 Series, key develop- ments allowed for performance enhancement in each area without compromise in others.

    4.1.5 DEFINED The system overview illustrates that the KF700 Series development was driven by enhancing the acoustical performance of the loudspeaker systems as it relates to its arrayability. Each loudspeaker must therefore array effectively both horizontally and vertically. Consistent controlled coverage patterns in three dimensions guarantees predictable array results from venue to venue.

    Processor settings for specific array configurations are available in a variety of formats that can be programmed directly into many DSPs. Formats include text lists of parameters as well as processor-specific presets. These settings can be found on the EAW web site: ftp://ftp.eaw.com/Processing/.

    The power handling listed for each EAW transducer is a good indicator of the size of the amplifier that will safely drive it to full output under most conditions. Amplifier selection is dependent upon the load presented at the amplifier output. Each doubling of loud- speaker quantity doubles the required amplifier power.

    5.5.2 APPROPRIATE HORIZONTAL CONFIGURATION The horizontal coverage angle required for a venue can be readily determined through examination of the plan view. Once the required horizontal coverage has been deter- mined, it is easy to calculate the number of columns required to thoroughly address the entire venue.
