Key Features
Relab QuantX Natural Resonance Reverb is a plugin recreation of a beloved ?80s hardware reverb, utilising resonators for highly realistic ambience. QuantX Natural Resonance Reverb gives you much more control over how your reverb sounds, especially in the high frequencies. While the original hardware naturally reduced brightness above 8kHz, QuantX lets you adjust this range from 4kHz up to 16kHz, so you can make your reverb darker or brighter depending on your mix. Instead of using a simple filter, it recreates how the original hardware shaped sound, resulting in a more natural and musical tone. This means your reverb doesn't just sit behind your sound, it blends in smoothly and adds depth without sounding harsh or artificial.
What makes QuantX stand out is how it captures the character of real vintage hardware, including its imperfections. Relab studied three original units from different parts of the world, each with its own unique sound from clean and precise to warm and slightly unpredictable. Using advanced technology and machine learning, they analysed how these units behaved over time, even down to how heat and ageing components subtly changed the sound. The result is a reverb that feels alive and organic, giving your tracks a sense of space and movement that goes beyond typical digital reverb plugins.

Traditionally, reverb emulations will use static models that ignore the internal movement and dynamics that hardware produces. Building off the incredibly popular LX480 reverb, Relab took to using next-generation advanced machine learning frameworks, analysing millions of data points to set new standards for hardware emulation that excels in reproducing the ever-changing dynamics of vintage gear.
Beneath QuantX’s front-facing UI is the dual-engine design that combines two powerful systems, each with its own set of four outputs, working together inside QuantX. With this approach, you can achieve a unique “front-to-back” reverb depth. Now, you can blending the distinct qualities of both modules of this twin-engine titan to ensure you can fit your reverb into any mixes.
QuantX is built differently. Rather than using time-based decay to generate a tone, QuantX uses resonators to replicate the behaviour of sound travelling through air. The room becomes an instrument, giving you reverb that has life and movement, that’s more integrated with the original sound for a completely natural and authentic reverb tone. This doesn’t mean you’re limited in the reverb length, with room size options from 1 to 1million cubic meters, you can go from tight reflections to endless tails.
Create the illusion of space with minimal reverb with the onboard Enhance feature inside QuantX. This simulates the sound of capturing the first bounce of audio across surfaces in a room, adding dimensionality to your track without introducing the muddiness that typically comes from layering long reverb tails.
Toggle between two unique reverb algorithms—a pristine, factory-spec German unit and a deeply characterful, time-worn US unit. With the Temperature Control knob, you can now emulate the evolution of sound from a cold startup to the warm, rich tones of a hardware unit left on for 72 hours. QuantX captures the essence of classic gear aging. The US algorithm faithfully recreates the quirks of an unstable crystal clock and aging components, while the German version delivers the stability and clarity of a freshly restored machine. Together, they offer sonic flexibility no competitor can match.
