Our take on the dbx DriveRack PX

by Bob Bihlmayer

The other half of the loaf

Powered speakers have many advantages including portability, compact size, and simplified setup. However, they lack the sophisticated features now available in outboard processing for non-powered speaker systems, leaving you with fewer options for enhancement and control of your powered speakers. To meet this need, dbx introduces the DriveRack PX, the first processor specifically designed to be used with powered speakers.

Advanced power management

The dbx DriveRack PX powered speaker optimizer offers a host of features for management of stereo powered speaker systems:

  •  Advanced Feedback Suppression (AFS) with 12 notch filters;
  • real-time analyzer and Auto EQ with the included M2 measurement mic;
  • pink noise generation;
  • dbx compression and PeakPlus stereo limiting.

The DriveRack PX also includes subharmonic synthesis for subwoofer enhancement and separate stereo subwoofer outputs.

Wizard digital control

You'll appreciate the simple setup with dedicated buttons for Auto-EQ and Advanced Feedback Suppression (AFS) wizards, along with presets for a number of popular powered speakers. These buttons give you direct access to the Wizard menus for quick configuration of the DriveRack PX's advanced RTA/Auto EQ, and Automatic Feedback Suppression (AFS) configuration features. These wizards and the menus for the PX's functions offer deep editing of each feature's parameters for control of your sound.

For optimization and control of powered speaker systems, the DriveRack PX offers a simple, powerful solution tailored to powered speakers. You'll be impressed by the improved sound of your system. Bring the power of dbx to your next show.
