dbx DriveRack PA2 Complete Loudspeaker Management System
Overview

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™ 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 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.
