Wave Distro announces Empirical Labs PUMP Duo 500 Series Rack

PUMP Duo Delivers Twin Empirical Labs Compressors In a Single Rackspace.

Ringwood, New Jersey. January 8, 2025 — Today, Wave Distro announced the PUMPTM Duo 500 Series rack, comprising a pair of Empirical Labs PUMP Classic Knee Compressor Modules mounted horizontally in a single-rackspace Wave Distro Powergrid Duo enclosure.

"The PUMP delivers the sound of our flagship Distressor® at half the price," said Empirical Labs President Dave Derr. “Plus, it even has some features that the Distressor doesn’t have, such as stepped Attack and Release controls for precise recall and manually syncing two PUMPs, the popular AtMod feature from our Arousor® plugin, a large user-friendly bargraph meter, and up to 10dB quieter operation. Now, there’s the PUMP Duo for stereo and dual-mono applications.”

The PUMP is a fully analog single-channel compressor that shares family DNA with the legendary Distressor compressor, along with select features from the Arousor compressor plugin and the Mike-e microphone preamp. The PUMP offers eight compression ratios from 2:1 to 20:1 (each with an optimized curve), digitally stepped Attack and Release controls, a Detector high-pass filter, soft-saturation clipping, and comprehensive gain-reduction metering.

The PUMP also boasts the unique Attack Modification or AtMod control originally introduced in the Arousor plugin and unavailable on any other hardware compressor. AtMod enables users to shape transient response beyond simply adjusting the Attack control, allowing more transients to pass for greater impact—such as adding a bit more snap to snares or thump to basses.

All Empirical Labs products are designed, manufactured, and assembled in the U.S.

The PUMP Duo is one of several Wave Distro Powergrid Duo 500 Series products. The Powergrid Duo features recessed slots that enable two 500 Series modules to be flush mounted for a clean look, and provides XLR inputs and outputs.

Whether used in stereo or dual-mono applications, the PUMP Duo provides two renowned Empirical Labs compressors in an elegant unit at an attractive price.
