Section 1- Introduction
The dbx 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
TM limiting. Your ears, your audience, and your powered speakers will forever thank
you.
