dbx DriveRack PA2 Speaker Management System

Tune your PA with dbx's AutoEQ room analysis, feedback suppression, graphic/parametric EQ, compression/limiting, alignment delay and crossover processing.

The dbx DriveRack PA2 provides all the processing you need between your mixer, and amplifiers to optimize and protect your loudspeakers. With advancements in dbx's proprietary AutoEQ and AFS algorithms, an input delay module for delaying the FOH system to the backline, Ethernet control via an Android, iOS, Mac, or Windows device -- along with updated Wizards -- the DriveRack PA2 continues in the legacy of great-sounding, powerful, and affordable loudspeaker management processors.

AutoEQ

The improved AutoEQ algorithm ensures an extremely accurate, fast, and non-intrusive automatic EQ experience. With the RTA Mic "listening" to your room, updated DriveRack PA2 AutoEQ algorithm sets speaker levels and room EQ automatically in a matter of seconds. This means room adjustments can now be made very quickly, without subjecting the audience to annoying, lengthy broadcasts of pink noise.

Enhanced AFS Feedback Elimination

Enhanced AFS algorithm for faster, more precise feedback elimination, without adversely affecting your system's tone. Nothing turns audiences away like annoying and potentially painful audio feedback. Fortunately, dbx engineers have revisited their already-stellar Advanced Feedback Suppression algorithm and made it work even better. The DriveRack PA2 listens for and anticipates feedback and adjusts speaker output automatically before it even has a chance, while never altering your sound.

Updated Wizard Setup Functions

Updated Wizards make initial set up read more easy, while ensuring speaker tunings and other settings are up-to-date. Wizard functions on the DriveRack PA2 guide you through easy, step-by-step processes to help you get the most from your loudspeaker system. Helps you easily configure level balancing, AutoEQ, Advanced Feedback Suppression, and provides access to built-in and constantly updating speaker tunings from most major speaker manufacturers.

We are a Grateful Dead Tribute band and we are in a different room every night. we have a rather odd speaker configuration. 2 JBL JRX 115s for our high ends, 2 JBL JRX 118’s for our mids and two SoundTech scoops for our bottom end. We demand the best sound we can give our fans and the difference between using a standard crossover and the DriveRack PA2 are night and day! Before getting the crossover and eq’s set was a nightmare and always sounded somewhat muddy. First night with the DriveRack and WOW… Crisp highs, great mids and the punchy bottom end were looking for. Although we can’t use the wizards for speaker and amp setup, going into the preset 13 (3 way stereo) and setting all the crossover points and roll offs was a cinch. Storing this new configuration was easy and painless. Now we walk in set everything up, do an initial gain structure set up without the cabs hooked up and then plug in the cabs. Hit the RTA and select Auto EQ and Level assist and it will tell you what amp and channel (right or left) to raise or lower the attenuation and gives you the db steps to raise or lower! As for quality, this thing is built like a tank! And only one rack space… Tech support was fantastic. I had a few questions and they were patient and precise. If you’re on the road and in a new venue every night this is money well spent! We still haven’t used all the functions, we only run 2 monitors and really don’t push a lot through them so feedback is generally read more not an issue but, it’s nice to know that if it occurs, we have the tool to fix it. The sub harmonic synth is really not something we need with the scoops, and so far have not tried it. This is not a plug and play device as you will have to read the directions a couple of times to take in all that this unite is capable of doing. But with a little knowledge and careful reading you should have no issues with setting it up! Overall this is the best investment we have made for the band period. We went for good sound to GREAT sound!
