DriveRack
™
By including every form of processing necessary to drive the signal from the mixer to the power
amp, the DriveRack™ allows you to eliminate all other processing devices that are normally
found in large and cumbersome traditional DriveRack systems of the past.
The 480 DriveRack™ Loud Speaker Management System includes four balanced XLR inputs, as
well as eight balanced XLR outputs, which can be routed for any configuration. The 481 and
482 DriveRack™ feature the identical processing power of the 480 DriveRack, but utilize stream-
line front panel interfaces. In addition, the 481 utilizes euroblock connectors as opposed to the
XLR connectors found in the 480 and 482 DriveRack.
The 480, 481 and 482 DriveRacks™ include features such as: pre-crossover EQ, dual RTAs, notch
filters, speaker delays, multiple crossovers and compression/limiting, as well as numerous other
features. Dual RTA analyzers can be run simultaneously with RTA source inputs capable of
being remotely switched on the fly. The 480 DriveRack™ is fully programmable from the front
panel, and can control other devices in a network including the 481 and 482 slave units. In
addition, the entire system can be controlled via the 480R DriveRack™ remote controller or
through the included GUI interface.
