The DriveRack® 442 Complete Equalization Management System is the latest product in the DriveRack

line. The 442 is based on the same operating system as the DriveRack

480 and offers the user four inputs and four outputs on XLR connectors. Each channel has EQ in the form of a 9-Band Parametric or a 31-Band Graphic and Notch Filters. In addition the 442 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 442 offers delay, output level and phase compensation. The 442 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 442. Any combination of 480s, 481s, 482s and 442s can be controlled on a single DriveRack

network consisting of up to 100 units.

The 442 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 442 DriveRack was designed with the purpose and vision of providing four independent channels of processing power that includes 31-Band Graphic equalizer, 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 www.dbxpro.com through the RS 232 port.
