RRS Passive EQ Collection is a comprehensive equalizer plug-in featuring three classic models: EQP-1A, MEQ-5, and HLF-3C. This AUv3 plug-in offers a time-limited demo version with 5 minutes of free playtime, which can be reloaded for repeated trials. The full version is available via in-app purchase.

This collection combines vintage equalizers, analog saturation, undo/redo functions, A/B comparison, and 2x/4x/8x upsampling. The EQP-1A replicates the renowned Classic Program Equalizer from the '60s, offering unique simultaneous frequency boosting and cutting. The MEQ-5 focuses on the "power region" for precise midrange control, while the HLF-3C provides passive high/low filtering without signal loss. Compatible with AUv3 hosts like GarageBand and Cubasis, Passive EQ Collection is a versatile tool for shaping your sound.
