® DriveRack PX POWERED SPEAKER OPTIMIZER Product Overview Powered speakers are a beautiful thing. Everything you need bundled into one simple, tidy, portable package. Just grab ‘em and go, right? Well, you may think your powered speaker system is complete, but you’re missing half the picture. While powered speaker manufacturers do their best to optimize the sound of their speakers in a controlled enviroment, they have no control over the actual location in which they are used. Enter the DriveRack PX - the other half of the picture. In another dbx industry first, we’ve created a processor specifically tailored for powered speakers. Utilizing our 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 M2 measurement mic, Auto-EQ corrects for audible deficiencies in the room environment. Our patented Advanced Feedback Suppression kills nasty feedback, allow- ing problem-free operation at higher sound levels, while our patented Subharmonic Synthesizer extends bass response for enhanced bottom end. With all that, and the protection offered by our graceful PeakPlus™ Limiting, your ears, your audi- ence, and your powered speakers will forever thank you. In spite of all that sophistication, rest assured we won’t overcomplicate the simplicity of your rig. Our exclusive Setup, Auto-EQ, and AFS Wizards, and out-of-the-box support for a host of popular powered speakers, make setup a snap. Louder, clearer, better sound than you thought possible from your powered speakers.
