* with subwoofers as a cardioid array, use [SB15_100_C] or [SB15_100_Cx]
[xx_MO] presets for the X series use the amplied controller low latency operating mode. When used along with
subwoofers, it is recommended to use the subwoofers in low latency operating mode. To achieve this, create
custom presets combining low latency channel sets and subwoofer channel sets.
If the subwoofers are driven from a dedicated amplied controller using a subwoofer factory preset, they are
operated in normal latency mode. Therefore, an additional delay should be set to the [xx_MO] low latency
channels to align them: 2.66 ms on LA8 or 3.00 ms on LA4X and LA12X.
