Drive your PA to a whole new level of performance with the DriveRackTM PA Complete
Equalization & Loudspeaker Control System. The DriveRack PA from dbx Professional
Products represents a complete integration of the key elements that help ensure optimal
loudspeaker system management in PA-specific applications. Capitalizing on the legendary
480 DriveRack technology, the DriveRack PA is able to provide its user with top-tier, prolevel loudspeaker management specifications, yet still remain appealing to the budget-conscious audiophile who requires a tried and true utilitarian workhorse. With its all-inclusive,
no-compromise design, the DriveRack PA has been systematically developed and designed
to grow with your system needs for years to come.
The DriveRack PA continues the legacy of DriveRack series, which has been created by the
company that has been redefining the standard of signal processing for more than 30 years.
The DriveRack PA was designed with the purpose and vision of providing state-of-the-art
signal processing, while utilizing a simple and intuitive user interface. This goal has been
achieved by offering two independent channels of processing power with a linkable 28Band Graphic equalizer, industry-standard dbx® stereo compressor module, feedback eliminator and the 120A Subharmonic Synthesizer on the input, with a six channel output system that includes parametric EQs, and Peak Plus™ limiters (which are used to provide protection against speaker blowouts) and alignment delay. These features combined with the
Wizard setup system, represent a methodical design that is guaranteed to deliver optimal,
all-inclusive processing in a completely scalable system. For more information, please visit:

At the heart of the DriveRack™ system is the 480. The 480 includes 4 inputs
and 8 outputs which can be tailored for any configuration. By including every form
of processing necessary to drive the signal from the mixer to the power amps, such
as pre-crossover EQ, notch filters, speaker delay, multiple crossovers, speaker compensation equalizer, driver alignment delay, and compression/limiting, the 480 is truly
the only box you’ll need for any sound system application. Two real time analyzers
can be run simultaneously with RTA source inputs capable of being remotely
switched on the fly. The 480 is fully programmable from the front panel, with the
480R remote control, or through a computer via the PC port.

The 481S and 482S include all of the functionality and features of the 480. They
both incorporate 4 inputs and 8 outputs with Euroblock connectors on the 481S and
XLRs on the 482S. However, they do not include the front panel programming interface. All programming functions can be performed through the 480, the 480R, or via
the Windows GUI. An unlimited number of DriveRacks™ can be chained together.

480R Remote for DriveRack™ System
480R Remote (optional)
The 480R is the remote controller for the entire DriveRack™ system. It is
capable of controlling and programming multiple 480, 481S, and 482S units. It features 31 motorized faders which automatically recall the Graphic EQ settings of any
unit on the network. The 480R can simultaneously control multiple DriveRacks™,
allowing global EQ adjustments to be made quickly. Thirty-two instant access buttons can be programmed to immediately recall the parameter screens that you use
the most. The large custom display mirrors the display of the selected unit, and the
480R also includes its own real time analyzer. The 480R can be stationed up to 500
feet from the master DriveRack™, making it the perfect choice for front-of-house
mixing.
