Eagerly anticipated update.

The dbx Driverack is one of the most innovative and helpful tools to come along for the live sound engineer in decades. It incorporates crossover, EQ, compression, delay parameters and much more within individual presets. These presets can then be applied to specific rooms, expected environments and applications. The dbx Driverack PA2 incorporates heavily researched and well-considered improvements in the original Driverack system.

The DriveRack PA2 provides all the processing you need between your mixer and amplifiers to optimize and protect your loudspeakers. With the latest advancements in dbx's proprietary AutoEQ and AFS algorithms, a new input delay module for delaying the FOH system to the backline, Ethernet control via an Android, iOS, Mac, or Windows device, and updated Wizards, the DriveRack PA2 continues the DriveRack legacy of great-sounding, powerful, and affordable loudspeaker management processors, for a whole new generation.

New, improved AutoEQ algorithm ensures an extremely accurate, fast, and non-intrusive automatic EQ experience.

With the RTA Mic "listening" to your room, the new, updated DriveRack PA2 AutoEQ algorithm sets speaker levels and room EQ automatically in a matter of seconds. This means room adjustments can now be made very quickly, without subjecting the audience to annoying, lengthy broadcasts of pink noise.

Enhanced AFS Feedback Elimination
Enhanced AFS algorithm for faster, more precise feedback elimination, without adversely affecting your system's tone.

Nothing turns audiences away like annoying and potentially painful audio feedback. Fortunately, dbx engineers have revisited their already-stellar Advanced Feedback Suppression algorithm and made it work even better. The DriveRack PA2 listens for and anticipates feedback and adjusts speaker output automatically before it even has a chance, while never altering your sound.

Updated Wizard Setup Functions
Updated Wizards make initial set up easy, while ensuring speaker tunings and other settings are up-to-date.

Wizard functions on the DriveRack PA2 guide you through easy, step-by-step processes to help you get the most from your loudspeaker system. Helps you easily configure level balancing, AutoEQ, Advanced Feedback Suppression, and provides access to built-in and constantly updating speaker tunings from most major speaker manufacturers.

DUMMIED DOWN version of original

By Shaggy

from Atlanta Georgia


  • Draw Eq
  • Lots of tools
  • Wireless Control


  • Limited Speaker Library
  • No Info On How To Update
  • No Manual Spkr Config
  • Wizard "not Listed" Poor

Best Uses

  • Amateur
  • Bad
  • Issues
  • Library Update Issues
  • Speakers Not Listed
  • Tunings Limited
  • Tunings Not Listed

Right to the point:
- if your speakers are not in the very limited library then only option is as follows:

No option for ACTIVE speakers, so the wizard assumes that it is a passive system.

- No straight forward input / output gain control

- No ability to manually configure not listed or custom speaker specs as in original DRIVERACK PA

- No ability to configure speaker gain / voltage settings so gain structure is correct.

- Even though DBX and all sites restate DBX rhetoric about how easy it is to update / download new speaker tunings either from DBX or directly from speaker manufacturers, there are NO CLEAR WAYS to do this, and no screen shots or any step by step instructions. Just words saying it is easy ...?

Love it

I use it to mobile Dj events from 250-10, 000 people outdoor. It protects my high end Peavey, EV, and Crown equipment. I love it. Will be adding another one to my other set ups.

    I have used various iterations of the DBX DriveRack on numerous system installations. Does a great job of tuning the system automatically, thus eliminating need for pink noise, and a big graphic EQ in the system. Of perhaps more importance is the very comprehensive feedback elimination on the mains. 6 fixed filters and 6 live filters. Just about totally eliminates feedback on a system that is driven hard. I don't do installed system without it, nor do I do larger live "protables" without DBX DriveRack on board.


    Impressive so far!

      Purchased this for shows as we run our own sound and figured the auto feedback suppression alone is so helpful. Haven't had a chance to use live yet, but did set it up for rehearsal. Wizards were all easy to follow, RTA mic (separate purchase) worked great. Definitely a noticible difference with the auto eq from our normal mix, which is usually pretty good, but it's like someone removed a blanket from the front of the speakers. Also, with our rehearsal space/set-up one mic is prone to feedback because it's close to a speaker. The auto-feedback worked great and there wasn't an issue all night! Used an old wifi router and had wireless iPad control in no time, very cool. So very happy so far!!!
