Empirical Labs EL-P Pump DUO Horizontal — a pair of PUMP Classic compressors mounted horizontally in a single-rackspace Wave Distro PowerGrid Duo enclosure, built for stereo or dual-mono use.

This set is aimed at studios needing two identical PUMP compression paths without building their own 500 series rack from scratch. The PowerGrid Duo enclosure integrates XLR input and output connectors directly into a single-rackspace unit, removing the need for a separate power supply and lunchbox for two modules.

Consistent Stereo Compression Without Manually Syncing Two Units

Building a stereo pair from two separate single-channel compressors often runs into mismatched behavior between the two paths, caused by production tolerances or imprecise setting alignment. PUMP Duo solves this with digitally-stepped Attack and Release knobs that let identical settings be precisely and repeatably reproduced on both modules, while the ability to manually sync two PUMP units helps maintain a coherent stereo image on a mix bus or across an overhead pair.

Preserving Transients Across a Dual Compression Path

Heavily squeezing a stereo signal usually costs instrument attack — a drum bus or mix bus loses its punch even if the rest of the signal sounds dense and controlled. The AtMod function, present on both PUMP Duo modules, solves this by slowing the initial slope of the attack envelope, letting more transient content back into the signal without giving up the intended compression level on either channel.

KEY FEATURES

  • 2 PUMP Classic compressors mounted horizontally in a single 1U enclosure
  • Wave Distro PowerGrid Duo chassis with built-in XLR input and output connectors
  • 8 selectable compression ratios per module: 2:1, 3:1, 4:1, 6:1, 8:1, 10:1, 12:1, 20:1
  • AtMod (Attack Modification) function on both channels simultaneously
  • Digitally-stepped Attack and Release knobs for precise, repeatable recall
  • Opto-coupler-style Release option (auto-release)
  • Switchable 70Hz detector high-pass filter on each module
  • Operates up to 10dB quieter than the flagship Distressor
  • Built for stereo and dual-mono applications
  • Designed, manufactured, and assembled in the U.S.
