The dbx DriveRack 480 4X8 Loudspeaker Management Processor is designed to be the only device necessary between your mixer and your power amps. dbx DriveRacks are all-inclusive loudspeaker management systems versatile enough to suit any sound reinforcement, monitoring, or install application.
The DriveRack 480 includes 4 inputs and 8 outputs on XLR connectors. Each channel has EQ in the form of a 9-band parametric or a 31-band graphic and notch filters. The 480 also features a filter set that can be used to create a Highpass, Lowpass or Bandpass filter. Dynamics processing is available on all channels with a Compressor/Limiter that emulates the classic dbx 160.
The output section of the 480 offers delay, output level and phase compensation. The 480 is also capable of running dual real-time analyzers on channels three and four. A 480 master, a PC GUI, or a 480R remote can control the 480. Any combination of 480s, 481s, 482s and 442s can be controlled on a single DriveRack network consisting of up to 100 units. All features can be controlled by the included dbx Professional Products Interactive DriveWare software.
