DriveRack™
Complete Equalization & Loudspeaker Management System
DriveRack™
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-
®
480
ments including the
, which can act as the master
controller unit. The 480 is capable of controlling as many
481
482
and
units as your application requires
through the DriveRack™ network communication
interface. In addition, the entire system can be controlled
480R
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
post mix processing
capable of handling all of the
signal routing
master controller
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.
