Cardioid configuration
The cardioid configuration corresponds to the use of subwoofers as cardioid subwoofer arrays. In this configuration, the
system produces a rear SPL rejection.
The [SB15_100_C] preset features a 100 Hz upper frequency limit and delay settings optimized for cardioid SB15m
arrays.
The SB15m subwoofers are driven by the LA4, LA4X or LA8 amplified controllers.

Delay settings
When combining a line source with subwoofers, delays may have to be added to the presets. Refer to the
PRESET GUIDE to obtain the pre-alignment delay values.
OBLIGATION
Place the subwoofer enclosures side by side. If not possible, the maximum distance between two adjacent
acoustic centers must be 1.7 m.
