Everything you need to get the most out of your stereo powered speaker system.

Powered speakers are beautiful things. Everything you need bundled into simple, tidy, portable packages. Just grab 'em and go, right? Well, you may think your powered speaker system is complete, but you're missing half the picture. DriveRack PX is the other half. With the PX, dbx has created a processor specifically tailored for powered speakers.

Utilizing dbx's highly acclaimed DriveRack technology, the PX picks up where your powered speakers leave off. The DriveRack PX Powered Speaker Optimizer has everything you need to get the most out of your stereo powered speaker system. It even includes stereo or mono subwoofer support. With the included dbx M2 measurement mic, Auto-EQ corrects for audible deficiencies in the room environment. Dbx's patented Advanced Feedback Suppression (AFSTM) kills nasty feedback, allowing problem-free operation at higher sound levels, while dbx's patented Subharmonic Synthesizer extends bass response for enhanced bottom end.

With all that, you also get classic dbx compression and the protection offered by dbx's graceful PeakStopPlus limiting. Your ears, your audience, and your powered speakers will forever thank you. In spite of all that sophistication, rest assured dbx won't overcomplicate the simplicity of your rig. Dbx's exclusive Setup, Auto-EQ, AFS Wizards, and out-of-the-box support for a host of JBL and other popular powered speakers, make setup a snap. Louder, cleaner, better sound than you thought possible from your powered speakers.
