The 590 Dynamic EQ delivers a rich, analog character through its five-band dynamic equalization, powered by MIA Laboratories' unique envelope detector inspired by classic analog circuitry. Each band offers dynamic control with compression or expansion modes, combined with precise double-precision processing and optional x4 oversampling. This design allows for smooth and controlled dynamic response, giving users the ability to shape sound with both subtlety and intensity. Attack and release parameters extend up to 200 ms and 2000 ms, enhancing flexibility in dynamic shaping.

Beyond dynamic control, the 590 introduces tonal color and harmonic enhancement via its Color and Distortion features. The Color function applies tailored filters to enrich harmonic and subharmonic content related to the selected frequencies, resulting in a natural and musical timbre shift. Lower bands emulate slower tube pre-amps for a sense of depth, while upper bands reflect fast Class A pre-amps to accentuate presence. Additionally, the Distortion knob recreates the warm, triode vacuum tube harmonic distortion, allowing users to inject analog warmth without extra gain stages, enhancing the overall sonic texture.

User experience is enhanced with intuitive preset management and workflow tools integrated into the interface. Navigation through presets, undo/redo options, and an A/B comparison feature enable efficient sound design and refinement. A selection of factory presets is included, alongside the option to create and save custom settings accessible across all plugin instances. These thoughtful features make the 590 Dynamic EQ a powerful tool for adding dynamic control and analog warmth to any audio production.
