Cla-2a Compressor Limiter

CLA-2A Compressor Limiter by Waves is an analog-modeled plugin based on the legendary Teletronix LA-2A optical leveling amplifier. It is widely used for its smooth, musical compression and simple two-knob interface, making it a favorite for vocals, bass, and guitars. Core Controls and Features

Sonic Character

• Warm, round low-mids.
• Soft high-frequency roll-off.
• Adds subtle harmonic distortion when driven hard.
• “Invisible” compression until pushed.

Unlike fast-acting FET compressors like the CLA-76, the CLA-2A utilizes a unique electro-luminescent optical attenuator. In the original hardware, this "T4" cell used light to trigger gain reduction, resulting in a program-dependent response that is naturally smooth and transparent.

User Interface: 9/10

• Peak Reduction – sets amount of compression.
• Gain – makes up for level loss.
• Limiter/Compress switch – two ratio/speed curves.
