EKX Powered Loudspeakers 7.6 Cardioid Control Technology The EKX-15SP and EKX-18SP subwoofers have cardioid array processing originally developed for Electro-Voice concert subwoofer systems. Cardioid subwoofer arrays can be used to direct the output of an array of subwoofers in order to limit excessive amounts of bass in undesired areas. These arrays can be used to keep bass off of a stage, provide more consistent bass coverage in the audience, and reduces bass in the surrounding area.
en 39 Figure 7.2: Cardioid physical alignment Cardioid option A: Either two (2) EKX-15SP or two (2) EKX-18SP subwoofers orientated vertically. Direct the top subwoofer towards the audience and the bottom subwoofer away from the audience (Rejection direction). Cardioid option B: Either three (3) EKX-15SP or three (3) EKX-18SP subwoofers orientated vertically. Direct the top two (2) subwoofers towards the audience and the bottom subwoofer away from the audience (Rejection direction).
EKX Powered Loudspeakers 8 Troubleshooting Problem Possible Cause(s) Action 1. Amplifier Connect a known working test loudspeaker to the No sound amplifier outputs. If there is no sound, verify all the electronics are on, the signal routing is correct, the source is active; the volume is turned up, etc. Correct/repair/replace as necessary. If there is sound, the problem is wiring. Wiring Verify you have connected the correct cables to the amplifier.
en Problem 7. Possible Cause(s) Action Incorrect gain Verify level controls of the source are properly structured structure or source by using the VU meter indicator on the LCD screen. If the input (mixing VU meter bar is solid or the system indicates LIMIT, the console/preamp) is input or source level is too high. Fore more information, overdriven see System status, page 21.
