Live productions have traditionally required a compromise between studio-grade effects and the reliability demanded on stage. The Allen & Heath Avantis RackUltra FX upgrade eliminates that compromise by bringing an expanded suite of effects directly into the Avantis platform. Powered by a dedicated hardware expansion card, RackUltra FX adds advanced reverbs, vocal processing, saturation, distortion and spatial effects without relying on external computers, plug-ins or servers. The result is a streamlined effects environment designed to elevate live productions while maintaining the stability and ultralow-latency performance professional engineers expect.

Studio-Class Effects Built for Live Sound

RackUltra FX expands Avantis with a collection of effects that rival many of today's leading studio plug-ins. Advanced vocal tuning and grid-based pitch correction support everything from subtle refinement to dramatic creative textures, while dedicated saturation processors and amp/cabinet models add warmth, color and harmonic character to vocals and instruments. Engineers also gain access to expansive reverbs, pristine delays and immersive spatial processors capable of creating everything from natural ambience to cinematic soundscapes, all running natively within the console. The upgrade also adds eight dedicated RackUltra FX engines, making sophisticated effects available without consuming existing channels, buses or RackExtra FX resources.

Dedicated Hardware Performance Without External Systems

Unlike software-based solutions that rely on laptops or external processing hardware, RackUltra FX operates entirely from a dedicated expansion card within the Avantis ecosystem. This approach minimizes latency, eliminates many of the risks associated with computer-based systems and ensures critical effects remain immediately available throughout demanding productions. Whether supporting concerts, theatrical performances, houses of worship or broadcast environments, the Avantis RackUltra FX upgrade provides a reliable way to expand creative capabilities while maintaining the speed and consistency required in professional live sound applications.
