  • Page 11 To use LEOPARD and 900-LFC loudspeakers in Native mode, send an identical, unmodified signal to each element in the array. The simplest way to accomplish this task is by looping the same, unprocessed source signal through all array elements.
  • Page 12 CHAPTER 1: INTRODUCTION NOTE: For Native mode to work properly, the source signal must be correctly configured with the appropriate gain structure. CAUTION: Make sure that all cabling for looped loudspeakers is wired correctly (Pin 1 to Pin 1, Pin 2 to Pin 2, and so forth) to prevent the polarity from being reversed.
