DBX DRIVERACK PX POWERED SPEAKER OPTIMIZER
dbx® Professional Products, a Salt Lake City-based manufacturer of professional signal processing products and a division of Harman International, introduces the new DriveRack® PX Powered Speaker Optimizer. The PX is the latest in the acclaimed dbx DriveRack family of products, which provide flexibility, sonic excellence and intuitive control for performance applications. Specifically, the new PX is designed to enhance and optimize the performance of powered speakers, all in an intuitive package that requires no special skills to operate.
Utilizing the highly acclaimed DriveRack technology, the PX is the first processor in the industry specifically tailored for powered speakers. Although powered speakers by definition require no amplifier or external processor, the DriveRack PX is an indispensable addition to any powered speaker setup, as it hosts a number of impressive features that offer louder, cleaner, better sound than had previously been possible from a powered speaker system.
An included dbx M2 measurement mic uses Auto-EQ to correct for audible deficiencies in the room environment. dbx's patented Advanced Feedback Suppression (AFS™ ) kills harsh feedback, allowing problem-free operation at higher sound levels, and the patented Subharmonic Synthesizer extends bass response for enhanced bottom end. The graceful PeakStopPlus™ Limiting protects the speakers without sacrificing overall sound quality.
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. DriveRack PX is the other half. 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 dbx M2 measurement mic, Auto-EQ corrects for audible deficiencies in the room environment. Our patented Advanced Feedback Suppression (AFS™) kills nasty feedback, allowing problem-free operation at higher sound levels, while our patented Subharmonic Synthesizer™ extends bass response for enhanced bottom end. With all that, you also get classic dbx compression and the protection offered by our graceful PeakPlus™ limiting. Your ears, your audience, 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 JBL and other popular powered speakers, make setup a snap. Louder, cleaner, better sound than you thought possible from your powered speakers.
