Common Setups

ICL-R digitally steered line arrays and IC215S-R subwoofers

were designed to work together, both acoustically and mechani-

cally with the subwoofer supplying both the extra bass impact

needed by most musical productions and a solid mounting base

for the tall slender columns. Together, the two building blocks

form 6 useful configurations.

The unique interlocking hardware system with quick release pins

joins the line array and the subwoofer together into a rigid as-

sembly, allowing the subwoofers to be used as mounting bases

for the columns. When used as a mounting base, the subwoof-

ers also raise the line array above the floor.

ICL-R arrays perform best when their acoustic center, the point

of origination for the narrow acoustic beam, is several feet above

the ear level of the audience. If it’s placed lower, too much of

the sonic beam is absorbed by the first row of the audience and

never reaches those in the rear. If it’s placed much higher, the

narrow vertical beam tends to” light up” the center of the audi-

ence and drop off in both the front and rear.

This puts the ideal height for the bottom of an ICL-R array at

roughly four feet above the floor for a seated audience.

An IC215S-R standing on end is 4’ tall making the combina-

tion of an ICL-R array mounted on top of a standing IC215S-R

subwoofer an ideal arrangement for many setups.

An IC215S-R subwoofer laid on its side and a single ICL-R array

work well when space is available for them on the stage. Mount-

ing two stacked arrays on a single subwoofer is not recommend-

ed, as the assembly is unstable.

Dual subwoofer assemblies combined with either a single ICL-R

array or with two stacked ICL-R arrays are two other popular

configurations. The dual subwoofers provide the desired mount-

ing height for the array(s) and enough bass for even the most

demanding musical events.

Stacked ICL-R arrays provide tighter beam control than a single

ICL-R and a much higher output level. They are especially

desirable in reverberant rooms where tight control of the beam is

needed to deliver clear speech over a considerable distance.

When only speech is involved and the bass support provided by

the subwoofers is not needed, single or stacked ICL-R arrays

are an ideal solution. They can be attached to the truss work with

Chesebrough clamps or by removing the array’s rear pole/handle

and using the pole clamps to secure the array to the truss.

ICL-R arrays are also equipped with AeroQuip Fly-Track, so they

can also be easily flown from the truss with industry standard

AeroQuip hardware.
