3. UND AND DESCRIPTION TheKF860 VLA Series was originally deve oped to hap solve specific problems for high end entertainment industry events that featured both live and broadcast audiences Thekey design parameters were minimal array size high output and broadband pattern control Part of the KF860 Series solution was the application of configuration specific digital signal processing DSP to maintain pattern control over an exceptionally wide bandwidth Settings vary depending on the number of modules in the array and the angle between adjacent modules Thus two crucial elements of any KF860 Series application are accurately splaying the enclosures and appl ying the correct DSP settings BUILDING AND PROCESSING KF860 SERIES ARRAYS To maintain accurate and repeatable array angles EAW developed a unique all steel rigging system for the KF860 Series that eliminates guesswork The steel rigging plates that link modules together fit into steel tubing brackets on each end of the module and are secured with quick release pins The reader will find acomplete explanation of this rigging system on pages 7 and 8 of this quideas well asin the companion publication KF860 H ardware Instructions EAW has developed appropriate settings for the MX8600 Close Coupled Digital Processor to control each of the KF860 array configurations discussed in this guide These settings are available from the ftp file transfer protocol section of EAW s website www e
