Using the WA2A

Updated: Jun 29, 2020

This guide will provide a brief overview of the Warm Audio WA2A optical compressor, a clone of the Universal Audio Teletronix LA-2A classic levelling amplifier.

WA2A Controls:

1. The Limit/​Compress switch sets the ratio and knee — Compress gives you a soft knee and a 4:1 ratio, whereas Limit gives you a ratio of (around) infinity.

2. The Out­put gain pot controls the output level of the unit.

3. The Peak reduc­tion pot is effectively the threshold of the compressor

4. The VU Meter selec­tion pot changes what is shown on the meter between the gain reduction, or overall outputs of the compressor.


Note:

There are no attack or release controls on this unit as they are fixed (not user-adjustable). The attack is set to around 10ms, although this varies slightly according to frequency. The release is level and frequency dependant.
