Ensure that your powered speakers enjoy peak performance with the dbx DriveRack PX Powered Speaker Optimizer. The DriveRack PX features Auto-EQ, Feedback Suppression, and a host of other useful tools that will improve sound quality and protect your powered speakers in any live sound application.

Improve Powered Speaker Performance

The DriveRack PX boasts much of the same renowned technology found in other DriveRacks, but tailored specifically for use with powered speakers. The emphasis is on cleaning up speakers' sound and helping them use power more efficiently, thereby allowing for higher volume levels. Included preset programs cover most major speaker brands.

All The Essential Ins and Outs

On the back of the DriveRack PX are two XLR inputs with a +4db/-10db attenuator switch to handle different input levels. There are also Stereo Main and Sub XLR Outputs. Finally, you can plug the included dbx M2 Measurement mic into an XLR input on the front of the PX.

Includes Vaunted dbx Processing and Controls

Perfect your powered speakers' sound with the DriveRack PX's Dual 28-band Graphic EQ. If you need to adjust a signal's dynamic range, you can utilize the on-board Classic dbx Compressor.

Auto-EQ Instantly Senses the Nuances of a Room

Using the included dbx M2 Measurement Mic, the DriveRack PX adjusts a signal's equalization settings to correct for deficiencies in a room. For instance, if your speakers are in spaces that tend to attenuate out higher frequencies, the DriveRack PX will automatically compensate for this by boosting the highs in the signal.

Subharmonic Synth Adds Low-End Oomph

Another piece of dbx proprietary technology included with the DriveRack PX is the Subharmonic Synthesizer, which adds additional bass response to your speakers. The Subharmonic Synth is great for enhancing subwoofer performance, and can also help compensate in set-ups that lack a subwoofer.

Protection from Feedback, Prevention of Noise

Thanks to the PX's patented Advanced Feedback Suppression (AFS) system, annoying feedback will never find its way to your powered speakers. And its PeakPlus limiting technology prevents sound levels from ever reaching speaker- or hearing-damaging levels.

Easy to Use, Instant Results

If you're running live sound, you can't afford to skimp on sound quality. The dbx DriveRack PX is easy to set up and will improve powered speaker performance immediately. It's as simple as using the Setup, Auto-EQ, and AFS Wizards to get going, and then choosing a preset that aligns to your speakers. After those few simple steps comes the best part: enjoying great sound!

Product Description

The dbx DriveRack PX Powered Speaker Optimizer provides flexibility, sonic excellence and intuitive control for performance applications. Specifically, the PX is designed to enhance and optimize the performance of powered speakers, all in an intuitive package that requires no special skills to operate.

Designed for Powered Speakers

With its highly acclaimed DriveRack technology, the dbx DriveRack PX is the first processor that's specifically tailored for powered speakers. Although powered speakers by definition require no amplifier or external processor, the DriveRack PX is an indispensable addition to any powered speaker setup, as it provides a number of impressive features that offer louder, cleaner, better sound than had previously been possible from a powered speaker system.

Includes dbx M2 Measurement Mic for Auto-EQ

Included with the dbx DriveRack PX is the dbx M2 measurement mic, which uses Auto-EQ to correct for audible deficiencies in the room environment.

Feedback Suppression, Subharmonic Synth, and Peak Limiting

dbx's patented Advanced Feedback Suppression (AFS) kills harsh feedback, allowing problem-free operation at higher sound levels, and the patented Subharmonic Synthesizer extends bass response for enhanced bottom end. The graceful PeakPlus limiting protects the speakers without sacrificing overall sound quality.

Easy to Use with Any Powered PA System

Intuitive out-of-box support for a host of JBL and other popular powered speaker brands and models and support for either stereo or mono subwoofer models make the PX the turnkey processor solution for almost any possible powered speaker setup. The exclusive Setup, Auto-EQ and AFS Wizards make setup easy and fast, preserving the simplicity of the user's powered speaker system.

5 out of 5 (23 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Awesome DriveRack!"
Sound: The sound is clean, clear and detailed. It improves the bass response of any speaker. Makes any speaker sound its best. Feature: It is full of features eliminating the need for extra outboard gear. It is 3 or 4 units in one. Ease of Use: The auto EQ is awesome. With a little reading of the manual you can set up any system. The included mic lets you set up to any room's acoustics in minutes. It doesn't get any easier than that. Quality: The quality is top notch. DBX products are built with quality. Value: For the sound, quality, price and what it does, the value can't be beat. Manufacturer Support: Have not had a reason to call support. The Wow Factor: A must for any DJ or Band using powered speakers. Overall: I bought the DriveRack PX for my powered speakers to simplify my set up. It has done just that. I was already familiar with DBX since i have the DriveRack 260 and PA for my passive system. No need for extra crossovers, EQs, compressor/limiters, feedback control or real time analyzers taking up rack space. This unit does it all. With the included mic you can set up your system to any room's acoustics in a matter of minutes. For a Mobile DJ or Band this very useful and important. Great job DBX and Zzounds. I ordered the DriveRack PX 7/25/11 and got it 7/26/11. Just awesome!

zZounds has verified that this customer bought this product from us. "All you need ! Amazing !"
Sound: Wow, I just picked up one of these at a good price and it is simply an amazing piece of gear, Once all the parameters are set the sound is pristene, No clipping, ZERO feedback at far past unity gain, just awesome! It is worth the time and effort to learn how to use this unit trust me. Feature: Ok well it has features galore! I have replaced everything in my rack with just this! A compressor/gate, A 31 band EQ, A feedback destroyer pro and a bbe 362 sonic maximizer...all down to this unit alone, the subharmnic synth is awesome and brings great punch to the bottom end! The limiter compressor feature just adds to that! No worries about blown speakers or annoying feedback, this unit has the best feedback destroyer I have ever used, its so super fast and so easy to use! Simply put, this is the only piece of rack gear you need, I now have in my rack, this unit, a powerconditioner and a power amp, where I needed 8 space rack before I am down to 4.Dont forget also this comes with the RTA mic?? valued at $100 alone??? Its a great deal! and DBX outdid themselves here Ease of Use: In the wizard mode its very easy, it gets more complex in the manuel mode, since I do not have speakers that are listed I had to do mine manually, in the end all worked out fine but it took some time so be patient! Quality: seems very solid and well made I have no issues and I use it live on the road! Value: Considering the amouint of rack gear this replaces, its a no brainer, its worth $400 all day long so its a great buy, even if you baught cheap behringer $99 dollar gear you would spend over that to get all the features of this unit, Its a great Buy! Manufacturer Support: Called DBX once and they ansered my call right away and took care of my question? what more can I say The Wow Factor: If you want trouble free all in one signal processing, yes you want this! Overall: hopefully a long time, if it were to break i would replace it ! DBX quality is great.
