Connecting the SB18 to the LA4 or LA8

Each of the SB18 subwoofers is connected to an LA4 or LA8 output channel ranging from channel 1 through 4 where
the channel 1 is feeding the reversed subwoofer. On the LA8 only, an additional subwoofer can be grouped in pair with
each first one so as to build a second basic cardioid array. Therefore a single LA4 amplified controller can drive 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 SB18 is connected to the OUT 1
output channel.
