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. When using speakers not listed

in the DriveRack PX, you should select ‘Custom’ for these components.

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.

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.

4. 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. Turn on your powered speakers and subwoofers now.

5. Now let’s create a preset to match your powered speakers. This preset is based on JBL PRX515’s and

JBL PRX518’s for illustration purposes.

4. 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. Turn on your powered speakers and subwoofers now.

5. Now let’s load the preset you created to match your powered speakers (from the ﬁrst half of this quick
