CABLE SELECTING
Selecting a cable consists of calculating the correct cable section (size) in relation
to the load impedance and the required cable length. A small cable section will increase its
serial resistance, which will induce power-loss and response variations (damping factor).
The following table indicates, for 3 common sizes, a cable length with a
maximum serial resistance equal to 4% of the load impedance (damping factor = 25):
Cable section

RIGGING THE SYSTEM
The LAs118 has a simple and intuitive four-point rigging system. It has 2
articulated joints on the front and 2 rear sliding joints.
In order to suspend a LAs118, you’ll need to use the NEXT NC18123 frame. This
suspension frame is built specifically to suspend the LA122/122W and/or LAs118 elements. It
makes possible the suspension of up to 6 LAs118 subwoofer elements. For more information
about the NC18123 frame or the LA122/122W Line Array elements please refer to their user’s
manual.
