    With a fixed horizontal directivity of 110° and a vertical inter-element variation from 0˚ to 10°, the KARA line source is fully configurable to match any audience geometry. The KARA system can be deployed either as a main system (FOH or distributed) with the SB18 subwoofer, as a compact complementary system (delays or fills), and even as a dedicated K1 downfill extension for stadium and arena concert applications.

  • Page 8: Loudspeaker Configurations

    3 LOUDSPEAKER CONFIGURATIONS Line source Deployed as a standalone line source, a KARA system operates over the nominal bandwidth of the KARA enclosure. The [KARA] preset allows for a reference frequency response in long throw applications. The KARA enclosure can be driven by the LA4X or LA8 amplified controllers.
  • Page 9: Line Source With Low-Frequency Element

    Line source with low-frequency element In this configuration, a KARA line source deployed with SB18 or SB28 subwoofers, the system bandwidth is extended in the low-end. The [KARA] preset allows for a reference frequency response in long throw applications. The [SB_60] or [SB_100] presets provide the SB with an upper frequency limit at 60 Hz in separated configuration, or 100 Hz in closely coupled configuration, for an optimal frequency coupling with the KARA line source.
