7.3.2 Connecting the SB118 to the LA4 or LA8
Each of the SB118 enclosures is connected to an LA4 or LA8 output channel ranging from channel 1 through 4 where
the channel 1 is feeding the reversed enclosure. On the LA8 only, additional cabinets can be grouped in pairs in parallel
with the first ones so as to build a second basic cardioid array. Therefore a single LA4 amplified controller can drive up
to one basic cardioid array (Figure 11) and a single LA8 amplified controller can drive up to two basic cardioid arrays
(Figure 12).
To achieve a cardioid coverage pattern always check that the reversed SB118 is connected to the
OUT 1 output channel.
