DBX DriveRack 480 EQ and Speaker Control Processor

No longer available at zZounds
31 band graphic or 9 band parametric equalizer, Dual Real Time Audio Analyzers

At the heart of the DriveRackĀ® system is the 480. The 480 includes 4 inputs and 8 outputs which can be tailored for any configuration. By including every form of processing necessary to drive the signal from the mixer to the power amps, such as pre-crossover EQ, notch filters, speaker delay, multiple crossovers, speaker compensation equalizer, driver alignment delay, and compression/limiting, the 480 is truly the only box you'll need for any sound system application. Two real time analyzers can be run simultaneously with RTA source inputs capable of being remotely switched on the fly. The 480 is fully programmable from the front panel, with the 480R remote control, or through a computer via the GUI port.
