® ® PX Quick Start Guide An illustrated guide to setting up your DriveRack® PX
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 diagrams of additional setups, refer to your User’s Manual.) If you’re not using subwoofers, just disregard instructions 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.
First-time Setup - Creating a New Preset 1. Remove the DriveRack PX from its box. Rack mount the DriveRack PX and connnect the power cord.

Connect the mixer left and right outputs to the DriveRack PX Left/Mono and Right Inputs.
. Turn the mixer master faders down. Turn on the mixer. Make sure the controls on your powered speakers are set the same on both speakers. For example, if you’re using subs, and they have a polarity setting, make sure they’re both set to the same polarity. Also, if your powered speakers have a Mic/Line setting, make sure they’re both set to Line, and if they have their own EQ settings, disable the EQ settings on the powered speakers. Turn the level control knobs on your powered speakers all the way down.
