The goal was quite simple: design an all-inclusive product that offers a complete inte-

gration of all of the elements required to achieve state-of-the-art loudspeaker manage-

ment. This design goal was reached and exceeded with introduction of the DriveRack

®

series. The 481 DriveRack

®

includes all of the functionality and features of the 480

DriveRack

®

.  The 481 incorporates 4 inputs and 8 outputs using Euroblock connectors.

The 481 DriveRack

®

also has a streamlined front panel which makes it ideal for per-

manent install applications.  All programming functions of the 481 DriveRack

®

can be

performed through a 480 master, the 480R, or via the Windows GUI.  By using the

DriveRack

®

network system, up to 99 DriveRack

®

units can be chained together.

The 481 DriveRack

®

continues the legacy DriveRack

®

series, which has been created

by the company that has been redefining the standard of signal processing for more

than 30 years.  dbx

®

Professional Products has created a product that caters to

numerous applications in tour sound and sound contractor requirements.

The 481 DriveRack

®

was designed with the purpose and vision of providing four

independent input and eight output channels of processing power that include 31-

Band Graphic equalizers, as well as dbx’s own industry standard dynamics process-

ing.  All aspects of the aforementioned features can be controlled by the included

dbx Professional Products Interactive DriveWare

software.  Software updates can

also be downloaded instantly from 

www.dbxpro.com

through the RS 232 port.
