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 streamline 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.
