01Overview

Audified built 1A Equalizer as a modern take on the classic Pultec EQ. The plugin keeps the signature boost-and-attenuate approach of the original hardware while adding tube-inspired saturation and precise calibration. A THD meter shows how much saturation is being applied, so you can judge the coloration as you work. Audified describes the plugin as an homage and evolution of the original design rather than an exact replica.

03In depth

Tube-Style Tone Shaping and Saturation

The core of 1A Equalizer is its boost-and-attenuate EQ, a signature approach borrowed from the original units. Boosting and attenuating lows or highs in the same band gives a characteristic curve that many producers associate with vintage hardware.

Saturation is central to the plugin. Audified says the saturation is calibrated to be precise and controllable, and a THD (Total Harmonic Distortion) meter lets you monitor how much harmonic coloration you are adding.

Mid/Side Processing and Routing

1A Equalizer includes Mid/Side (M/S) processing, which splits the audio into Mid and Side components. This lets you shape the center of a mix and the stereo edges separately.

Linkable parameters and switchable L/R and M/S modes give you control over how the stereo image is processed, whether you are mixing a track or working on a master.
