Empirical Labs PUMP™ Duo: Dual-Channel 500 Series Compressor for Professional Studios
The Empirical Labs PUMP™ Duo is a compact, dual-channel compressor designed for modern studio environments. It integrates two PUMP Classic Knee Compressor Modules into the Wave Distro Powergrid Duo 500 Series enclosure, offering exceptional performance for stereo and dual-mono applications. With features like stepped Attack and Release controls, AtMod transient shaping, eight compression ratios, and a large bargraph meter, the PUMP Duo delivers precise dynamics control with enhanced functionality and reduced noise for pristine audio processing.
Advanced Compression Technology
The PUMP Duo combines the heritage of the iconic Distressor® with cutting-edge design improvements. Each channel features:
- Fully analog circuitry for warm, transparent compression.
- Digitally stepped Attack and Release controls for precision adjustments.
- Eight optimized compression ratios ranging from 2:1 to 20:1, providing flexibility for everything from subtle leveling to aggressive limiting.
- High-pass filter in the Detector circuit, allowing users to focus compression on specific frequency ranges for greater tonal control.
- Soft-saturation clipping mode, introducing smooth harmonic distortion for enhanced musicality.
This blend of analog warmth and modern precision makes the PUMP Duo ideal for a wide range of studio tasks, from mixing and mastering to tracking.
Innovative Features for Superior Control
A standout feature of the PUMP Duo is its AtMod (Attack Modification) control, inspired by the Arousor® plugin. This advanced transient shaping tool allows users to fine-tune the attack characteristics of their audio, perfect for:
- Adding punch to percussive elements like snares or kicks.
- Taming aggressive transients in bass and other dynamic sources.
The large bargraph meter provides real-time visual feedback for gain reduction, ensuring precise operation during sessions. Additionally, the PUMP Duo boasts up to 10 dB quieter operation compared to the Distressor®, making it a top choice for engineers seeking clean and noise-free compression.
Elegant and Durable Design
The Wave Distro Powergrid Duo chassis integrates the two PUMP modules into a single rackspace, featuring:
- Flush-mounted module design for a sleek aesthetic.
- XLR inputs and outputs, ensuring seamless connectivity with studio setups.
- Recessed slots for added protection and practicality.
This robust design underscores Empirical Labs’ commitment to high-quality, USA-made products that stand up to the demands of professional use.
Unmatched Versatility for Studio Applications
The PUMP Duo offers:
- Stereo and dual-mono configurations for maximum flexibility. Users can manually sync the two modules for stereo operation or operate them independently for dual-mono tasks.
- Stepped controls, allowing for consistent recall of settings, essential in professional workflows where repeatability is crucial.
Whether you’re sculpting dynamics in a dense mix or adding subtle enhancements to individual tracks, the PUMP Duo provides the tools and precision needed for any application.
Exceptional Value and Appeal
The PUMP Duo is a significant addition to Empirical Labs’ lineup, delivering the celebrated sound of the Distressor® with modern enhancements at an accessible price. Its versatile design, intuitive controls, and innovative features make it an essential tool for audio professionals seeking cutting-edge compression with unmatched reliability.
