: It is the industry standard for leveling vocals without making them sound "squashed." It is often used as a second compressor after a faster one (like the CLA-76) to round out the sound. Bass Guitar
While the original hardware units sell for thousands of dollars per channel, the Waves CLA-2A democratizes that sound. As part of the Waves CLA Classic Compressors series—released in 2009—this plugin captures the specific frequency-dependent behaviors and low-harmonic tube distortion that define the unit. It is a staple for engineers seeking to add "glue," warmth, and presence to their mixes. cla-2a compressor limiter
When an audio signal enters the unit, it lights up the internal panel. The louder the signal, the brighter the light shines, causing the photo-resistors to lower the circuit's gain. This creates a completely unique timing response: CLA-2A Compressor Limiter Plugin - Waves Audio
The remaining release takes anywhere from 1 to 15 seconds, depending on how heavily the signal was compressed. Adjusts a high-frequency filter in the sidechain, leaving
While the price point is remarkably affordable, prospective buyers should be aware of the Waves Update Plan (WUP) , a paid plan for continued updates and support—a point raised in several user reviews.
The 2A is historically famous as a vocal compressor. Its slow, natural attack allows the initial transient of a word to pass through (preserving diction and clarity), while its smooth release glues the tail of the word down. Set the switch to and dial in the Peak Reduction until you see about 3 dB to 5 dB of gain reduction on the meter. 2. Bass Guitars As part of the Waves CLA Classic Compressors
On highly dynamic lead vocals, pair the CLA-2A with a fast FET compressor like the CLA-76. Place the CLA-76 first in your signal chain with a fast attack to catch the rapid, loud peaks (shaving off 2–3 dB). Follow it with the CLA-2A to smoothly level out the overall performance.
To set up this classic chain, place the CLA-76 first in your signal path with a fast attack and release. Set it to only catch the absolute loudest, fastest transient peaks (shaving off 2–3 dB of gain reduction). Follow it immediately with the CLA-2A. Because the CLA-76 already flattened the erratic spikes, the CLA-2A can do what it does best: smoothly level out the body of the vocal performance without being tripped up by sudden loud words. This combination delivers maximum vocal consistency and power without sounding over-compressed. Conclusion
