2. How to use White 2A
1 Although White 2A includes a small library of presets, the plugin is so dependent on the nature and level of the input signal that they’re really only there for the sake of completion. Take a quick tour of them if you like, then hit the Reset switch to set everything back to default.
2 The most important control is the Peak Reduction knob, which adjusts the compression threshold. At 0, no compression is applied at all, and as Peak Reduction increases, the threshold is progressively lowered, applying gain reduction first to just the peaks, and then more and more of the signal, until at 100 the whole lot is compressed or limited.
3 As a result of the compression, the overall signal will be quieter at the output than the input, to an extent determined by how far you’ve pushed the Peak Reduction. To compensate for this, simply boost the output volume by raising the Gain knob.
4 The LA-2A only has two ratio settings: Limit and Compress, toggled on White 2A with the switch at the bottom right. Compress works at a ratio of somewhere between 3:1 and 4:1, depending on the Peak Reduction setting and input level, while Limit ramps that up to inf:1.
5 When set to Compress, the input signal has to rise by 3 or 4dB to achieve just 1dB of gain at the output – ideal when you need transparent levelling of moderately over-dynamic instruments. The Limit setting, on the other hand, applies much heavier gain reduction for when you need to clamp down harder.
6 The LA-2A VU meter gives you three options when it comes to visually monitoring the signal, selected with the knob below it. Output +4 and Output +10 modes meter the output level on two different scales, while Gain Reduction mode lets you keep an eye on the amount of compression being applied.
