4 channels of dbx compression. Each channel has threshold, ratio and ‘OverEasy’ (between soft compression for overall gain control or Hard Knee compression based on the characteristics of the original dbx 160). Plus In/Out meter, output gain, bypass and PeakStopPlus.

You can stereo link channels 1&2 and 3&4. XLR and 1/4″ I/O, and switchable +4dBu or -10dBV operating level. 1U.


  • Four independent channels of operation, stereo linkable in two pairs
  • PeakStopPlus™ limiting control for setting maximum allowable level regardless of compressor settings
  • Independent Threshold and ratio controls
  • Switchable OverEasy® or Hard Knee compression
  • Classic dbx® compression
  • Differentially balanced gold-plated XLR and 1/4″ inputs and outputs
  • True RMS level detection
  • Precision metering of input level, output level, and gain reduction
  • Dual True stereo or quad mono operation
  • Switchable +4dBu or -10dBV operation per channel
