The dbx DriveRack PA+ is the complete solution for making your PA sound better.

Putting together a live rig once you have chosen your amplifiers and speakers can be a daunting and potentially costly task. EQ, compression, limiting, delay, as well as crossovers and dedicated outputs can not only occupy a chunk of your available rackspace, but can also add up in the cost department. Or you can just outfit your live rig with the dbx DriveRack PA+ and be done with it.

The dbx DriveRack PA+ can replace all those individual components and then some in a single rackspace with state-of-the-art circuitry specifically developed to manage your PA system. It’s a full-featured loudspeaker management system that is as easy to use as it is complex in design.

Start off with a 28-band real time analyzer and ring out the room for optimal equalization.

dbx developed the AFS (automatic feedback system) to address feedback issues invisibly and painlessly, utilizing 12 feedback notch filters to snuff out unwanted feedback loops throughout the gig. The famous dbx 120A Sub-harmonic Synthesizer is onboard as well, delivering that much sought-after extra bass boost as it drops the lowest bass signal down one octave resulting in bass you not only hear, but can truly feel. True dbx compression is present on the inputs to help keep all signals in check, and the dual 28-band graphic EQ helps to carve out a precision curve resulting in optimum sound levels.

The dbx exclusive Set Up Wizard will gracefully guide you through system setup with easy-to-follow step-by-step instructions. The DriveRack PA+ includes a built-in list covering popular speakers and amps that when chosen will allow the Auto Level Wizard to automatically fine-tune the level of each speaker. The Auto EQ Wizard will assist in further optimizing the sound followed by the AFS Wizard, which will automatically set the filters to eliminate any feedback. The USB port can be hooked up to a computer for firmware and speaker tunings, and is field updateable utilizing the Harmon HiQnet System Architect.

You need not be a professional sound engineer to tweak your whole system quickly and efficiently. The dbx DriveRack PA+ is a gigging musician’s dream come true. Never leave home without it.

Comments about dbx DriveRack PA+ Complete Loudspeaker Management System:

This box has an inbuilt auto setup graphic eq, cross over, subharmonic synthesizer, complimiter, feedback suppressor and realtime analyzer in a 1 unit box. It does ALL of these things very well and is an amazing value, even when you add the cost of the calibration mic.
I used this for an outdoor concert with a high energy country rock band with MULTIPLE identical powered speakers on each side and two 18 passive subs. The setup wizard is actually fun to use in a music techno geek sort of way.With the calibration mic you can truly unlock the power of this box to eq even moderately large arrays automatically. With this unit on the mains, the only feedback issues likely were from the wedges, which were easy to deal with during sound check. The show went nearly flawlessly.
The manual for such a powerful box is blissfully complete and very thin which is proof of the excellence of the design and power of the automatic features.
As far as I can tell, the main difference between the Driverack PA plus and its pricer bigger brother the Driverack 260 is the lack of a GUI which might further simplify things a bit and enhance the operators experience for the 260.

This is a must have for any mobile sound company or serious dj that is committed to providing the best sound.
