The EQP-1A is a classic program equalizer plugin inspired by a renowned '60s hardware unit, designed to streamline the mixing process with efficient handling of mid/side, stereo, and immersive audio objects. It eliminates the need for complex manual adjustments by offering dedicated workflows tailored for immersive mixing environments, including the ability to process entire grouped speaker zones with channel linking. This makes it an essential tool for producers working with modern multi-channel audio setups.

Faithfully modeled on the original hardware, the EQP-1A captures the unique sonic character of the vintage equalizer, known for its distinctive ability to simultaneously boost and cut the same frequencies, creating a resonant shelf effect. The plugin emulates the original unit’s robust transformers and complex tube amplifiers, providing rich analog saturation and warmth. Users can select from multiple low and high-frequency boost and cut points, along with precise bandwidth control to shape the high-frequency boost curve.

Designed for broadband equalization, the EQP-1A includes four independent equalizers in one plugin, covering a range of frequency bands with options for analog saturation on or off. While it supports surround sound profiles for immersive audio formats, some issues exist with certain DAWs due to external compatibility limitations. However, it operates flawlessly on platforms that fully support multi-channel AUv3 plugins, ensuring high-quality performance in a wide range of production environments.
