The Passive EQ Collection Immersive features three classic equalizers inspired by iconic hardware units from the 1960s and 1970s. The EQP-1A emulates the original Program Equalizer, known for its distinctive ability to boost and cut the same frequency simultaneously to create a resonant shelf effect. This model captures the character of overbuilt transformers and complex tube amplifiers, delivering rich and musical tonal shaping.

Included in the collection is the MEQ-5, a mid-range equalizer designed to enhance the critical frequency range where guitars and vocals stand out in a mix. It offers two bands for midrange boost and one band for midrange cut, allowing precise control over the power region of your audio. The HLF-3C completes the set with its low and high cut filters, providing broad tonal shaping reminiscent of vintage passives but without the typical insertion loss, making it ideal for creative sound design and retro-inspired effects.

Designed specifically for immersive mixing, this plug-in collection supports mid/side processing, stereo, and object-based workflows, streamlining the process of working within complex audio environments. While surround profiles currently have compatibility issues with certain DAWs due to external software limitations, the collection functions flawlessly in supported hosts, enabling fast and efficient equalization for immersive audio projects.
