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.
