•In the Sub Gain menu, adjust the level to compensate for the use of more or fewer subwoofers than a typical system.
•In the Sub Delay and Array Delay menus, you may add alignment delays if necessary. If the array is suspended below the subwoofer, the Sub Delay and Array Delay should be the same. If the
array is suspended in front of the subwoofer, the Array Delay should be 3.0 ms greater than the Sub Delay setting.
•In the Limiters menu, configure the output limiters to protect the loudspeakers or for clip limiting only of the SC28 output. Disabling the loudspeaker protection is not recommended.
