442 DriveRack Complete Equalization Management System. 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.
