The 481 DriveRack® also has a streamlined front panel which makes it ideal for permanent install applications. All programming functions of the 481 DriveRack® can be performed through a 480 master, the 480R, or via the Windows GUI. By using the DriveRack® network system, up to 99 DriveRack® units can be chained together. The 481 DriveRack® continues the legacy DriveRack® series, which has been created by the company that has been redefining the standard of signal processing for more than 30 years. dbx® Professional Products has created a product that caters to numerous applications in tour sound and sound contractor requirements. The 481 DriveRack® was designed with the purpose and vision of providing four independent input and eight output channels of processing power that include 31Band Graphic equalizers, as well as dbx’s own industry standard dynamics processing. All aspects of the aforementioned features can be controlled by the included dbx Professional Products Interactive DriveWare™ software. Software updates can also be downloaded instantly from through the RS 232 port. • 4 Input and 8 Outputs with routing • Separate House and Show EQ with indi• 31 band graphic or 9 band parametric vidual lockouts equalizer on every input (pre-crossover) • Triple redundant backup of all parame• Dual Real Time Audio Analyzers ters when running network, 480R and PC GUI • Butterworth, Bessel or Linkwitz-Riley • TYPE IV™ Conversion System crossover filters • Electronically balanced/RF filtered • 27 Different Crossover Configurations Euroblock Inputs and Outputs • Time Alignment and Transducer • Proprietary RS-485 Control Network Alignment Delays • RS-232 PC Interface for computer 8760 S.
