The Adamson Load Library (https://www.adamsonsystems.com/support/downloads-directory/design-and-control/e-
rack/245-adamson-load-library-5-0-1/file ) contains presets designed for a variety of IS118 deployments.

When flown in the same array as an IS7, all IS118 presets contain the inherent delay needed to be properly phase-
aligned.
When flown or ground stacked separately, IS118 subs should be phase-aligned using measurement software.
