DBX 266XS Compressor/Gate


DBX 266XS Compressor/Gate


DBX 266xs Compressor/Gate

Dual Compressor Gate Two channels of classic dbx compression with the new standard dbx internal power supply and AutoDynamic™ Attack and Release controls, as well as an OverEasy®/hardknee switch, program‐adaptive expander gates, balanced inputs and outputs, precision LED metering and sidechain insert, and +4/‐10 operation switch on the rear panel. Front panel selection of true RMS Power Summing™, stereo or dual mono operation.

  • Error proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten up mixes
  • New gate timing algorithms ensure the smoothest release characteristics
  • Program-adaptive expander/gates
  • Great sounding dynamics control for any type of program material
  • Separate precision LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup
  • Stereo or dual-mono operation
  • Balanced inputs and outputs on 1/4" TRS and XLR connectors
  • Side Chain insert
  • Classic dbx® "Auto" mode
