DBX PA2 Speaker System DSP Processor

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.

Everyone knows the biggest enemy of setting up a sound system in a new space: 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's tone.

Getting started is easy with the updated Set Up Wizard functions on the DriveRack PA2. It guides you through easy, step-by-step processes to help you get the most from your loudspeaker system, helping 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. And if you have the RTA Mic (sold separately), the AutoEQ algorithm sets speaker levels and room EQ automatically in seconds, saving you from annoying and lengthy broadcasts of pink noise.
