The is a perfect example of why

dbx has always been synonymous with innovative ideas and

a leader in cutting edge technology. Designed to be the

only device necessary between the mixer and the power

amps, the DriveRack™ exceeded our goal. Every tool you

could ever ask for has been included, and is completely

configurable.

The DriveRack™ is an all inclusive loud speaker man-

agement system versatile enough to suit any sound rein-

forcement,monitoring, or install application. There are five

components available in the DriveRack™ line providing

quick and easy solutions to every imaginable scenario

across the audio spectrum.

The DriveRack™ system is comprised of several ele-

ments including the ,which can act as the master

controller unit. The 480 is capable of controlling as many

and units as your application requires

through the DriveRack™ network communication

interface. In addition, the entire system can be controlled

and programmed by a single remote control

unit or by a PC via the GUI interface.

It seems like such a simple idea to have one system

capable of handling all of the

and ,with one

capable of communicating with all the processing at once.

However, it took the creative insight of a leader in audio

innovations to think of it. It’s no wonder that dbx has been

a legend in the audio industry for over 25 years.

Graphic EQ/Real-Time Analyzer/Parametric EQ/Notch Filter/Alignment Delay/Compressor/Limiter

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 481 and 482 include all of the functionality and features of the 480. They
both incorporate 4 inputs and 8 outputs with Euroblock connectors on the 481 and
XLRs on the 482. 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.

The 480R is the remote controller for the entire DriveRack™ system. It is
capable of controlling and programming multiple 480,481, and 482 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.
