03In depth

Sound, Bands and Stereo Processing

IK Multimedia says the plugin is based on a classic hardware mastering equalizer, and the developer credits its discrete, transformer-less signal path and custom op-amps as the source of its transparent character. The EQ is described as having independent parametric bands with little interaction between them.

Switchable gain ranges are included in a single model, combining what were previously three separate hardware versions. According to the developer, this lets each band use the best resolution of its gain range with fine precision.

The plugin can also switch between L/R and M/S processing. This allows Mid (center) content and Side content of a stereo mix to be equalized separately, a workflow the developer highlights for mastering.

Workflow and Digital Features

Master EQ 432 adds digital conveniences to its analog-style design. Total recall lets you restore settings instantly, and full automation is supported for changes over time.

The plugin is intended for mastering and final mix polish, though it can be used on individual tracks or buses where a precise parametric EQ is needed.
