Connection to LA4

To cable the SB18 subwoofers with the LA4 amplified controller, two options are available:
Option A:
Connect an SP cable (SP.7, SP5, SP10 or SP25) to the OUT1connector of the LA4, and use the SP-Y1 cable to split
the audio signals into two channels, each one feeding one enclosure. The CC4FP adaptor allows interfacing the SP and
SP-Y1 cables. Apply the same cabling scheme with the OUT3 connector to connect two more enclosures.
Option B:
Use an SP cable (SP.7, SP5, SP10 or SP25) to connect one similar enclosure to each of the four LA4 output channels.
Maximum of 4 SB18 per LA4
1 SB18 subwoofers can be connected to each output channel on the LA4.
Therefore, a single LA4 amplified controller can drive up to 4 SB18 subwoofers.
Subwoofer array in CARDIOID configuration
The reversed sub must be connected to OUT 1.
