Advanced Compression Options
The PUMP Duo provides a range of eight compression ratios from 2:1 to 20:1, featuring digitally stepped Attack and Release controls for precise manipulation, making it ideal for diverse audio processing demands.
The Empirical Labs PUMP™ Duo 500 Series rack is a compact, dual-channel compressor unit that combines two PUMP Classic Knee Compressor Modules in a single Wave Distro Powergrid Duo enclosure, offering a versatile and powerful solution for stereo and dual-mono audio applications, with features like stepped Attack and Release controls, AtMod transient shaping, eight compression ratios, a large bargraph meter, and quieter operation than its predecessors.
Advanced Compression Technology
The PUMP Duo delivers professional-grade audio compression derived from the renowned Distressor® while introducing enhanced functionality at a competitive price point. Each PUMP module features fully analogue circuitry, digitally stepped Attack and Release controls for precision, and eight optimised compression ratios ranging from 2:1 to 20:1, ensuring flexibility for various audio processing needs. The device also includes a high-pass filter in the Detector, which helps focus compression on specific frequencies, and a soft-saturation clipping mode for smooth, musical harmonic distortion.
Unique Features and Innovations
One of the standout features of the PUMP Duo is the AtMod (Attack Modification) control, an innovation borrowed from Empirical Labs' Arousor® plugin. AtMod enables nuanced shaping of transient responses, giving users the ability to emphasise or tame attack characteristics beyond traditional compressor settings. This feature is ideal for enhancing percussive elements such as snare drums or bass transients, adding punch and clarity to mixes.
The PUMP also offers a bargraph meter for intuitive gain-reduction monitoring, ensuring precise visual feedback during operation. Additionally, the unit operates with up to 10 dB quieter performance compared to the flagship Distressor®, catering to professionals seeking pristine audio quality.
Elegant and Robust Design
The PUMP Duo leverages the Wave Distro Powergrid Duo 500 Series chassis, which allows two 500 Series modules to be mounted flush within a single rackspace. The enclosure includes recessed slots for a clean aesthetic, as well as XLR inputs and outputs for seamless integration into studio setups. The design emphasises practicality and professional-grade build quality, aligning with Empirical Labs' reputation for manufacturing in the United States.
Versatility in Application
Whether employed for stereo or dual-mono tasks, the PUMP Duo offers unmatched flexibility and precision. Users can manually sync the two PUMP modules for stereo operation or use them independently for dual-mono configurations. Its stepped controls allow for consistent recall of settings, a crucial feature for studio environments requiring repeatable results.
Availability and Appeal
The PUMP Duo represents a significant addition to Empirical Labs' product line, delivering the iconic sound of the Distressor® with additional enhancements and modern features at an accessible price. It caters to audio professionals who demand high-quality compression tools that combine performance, innovation, and durability.
