®
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.
