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.
