dbx DriveRack PX Manual page 2

This Quick Start Guide will walk you through your first and subsequent setups, step by step. To keep things
simple, we'll use a common powered speaker setup: two mains and two subwoofers, shown below. (For dia-
grams of additional setups, refer to your User's Manual.) If you're not using subwoofers, just disregard instruc-
tions that refer to subwoofers. For this example, we'll use JBL PRX515's and JBL PRX518's, but you can use
almost any powered speakers and powered subwoofers with the DriveRack PX.
If you're using the DriveRack PX for the first time, begin on page 3.
If you've already set up and saved a preset for your powered speakers, and just want to optimize your powered
speakers for a new room or venue, begin on page 14.
