What White 2A Leveling Amplifier does
The plugin reproduces a design in which compression takes place entirely inside the device, with no electronic gain-control circuitry in the compression path itself. Instead, the signal drives a fluorescent panel that lights a set of photo-resistors, and the light level sets how much gain reduction is applied. The developer describes optical compression as the simplest approach available when the invention of the original unit was made, since a light-emitting panel and matched photocells were enough to build one. When driven harder, the tube output stage adds harmonic character that the developer names as the source of the unit’s personality.
Key features
- Tube output stage. A tube output stage is included, and the developer says it supplies harmonic content that increases as the unit is driven harder.
- Vocal and program material. The developer names vocals and music as the most common uses of the original unit, where it makes its character stand out in the mix.
- Bass and wide dynamics. The developer points to bass as a good candidate, where wide dynamics are kept gently in check.
- Digital-only additions. Compared with the physical design, the module adds digital-only features that the developer says become possible in a plugin setting.
