The EQP-1A based on Classic Program Equalizer from the '60s, original EQ is renowned for its unique ability to boost and cut the same frequencies simultaneously, thereby creating a resonant shelf, the EQP-1A faithfully models the overbuilt transformers and complex tube amplifiers of the original hardware.

Conceived and created for broadband equalization, the EQP-1A features 4 low boost/cut frequencies, 3 high-cut frequencies and 7 HF boost points, along with a bandwidth control for shaping the high boost curve.

The MEQ-5 based on Classic Mid-Range Equalizer from the '70s, with two bands of midrange boost and one band of midrange dip, the MEQ-5 gets the very best out of the «power region» where guitars and vocals can make or break a mix.

The MEQ-5 provides exacting control of the «power region» in program material, that frequency range from about 300 Hz to 5000 Hz in which most of the sound energy is concentrated. The ear is especially sensitive to sounds in this region. In this region, even small resonances in studio acoustics and microphone and speaker responses are very evident in their effect on the listenability of the sound. Three independent sets of controls make it possible to boost on a peak curve at 200…1000 Hz while simultaneously boosting on a peak curve at 1.5…5 kHz, while simultaneously dipping at 200…7000 Hz.

The original HLF-3C hardware unit is a true passive design: there are no input/output amplifiers and it does not require any external power. As a result, there is an inherent loss of signal level when using the HLF-3C hardware. The RRS HLF-3C compensates for this inherent signal loss for simplified use in the modern era: it has unity gain upon insertion (there is no insertion loss until one or both of the cut filters is engaged).

The broadband EQP-1A, the midrange MEQ-5 and the passive high/low filter HLF-3C together comprise a full range vintage EQ chain.

To use Passive EQ Collection as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — Passive EQ Collection will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
