Waves CLA-2A Compressor Limiter is a highly regarded digital emulation of the legendary Teletronix LA-2A

1. Aggressive Saturation: The CLA-2A introduces harmonic distortion much earlier. Even with no gain reduction, driving the input adds a thick, mid-forward color that helps vocals cut through a dense rock mix.
2. Faster Release Option: While the classic is purely program-dependent, the CLA-2A offers a "Faster Release" switch. This tightens up the low end on bass guitar and prevents the compressor from "pumping" on fast tempos.
3. The "Black" Aesthetic: Visually, it matches CLA’s personal "Blackface" unit—and sonically, it pushes harder than the standard silver unit.

The Secret: It’s Not a Limiter (It’s a Leveller)

The original hardware was called a "Leveling Amplifier," not a limiter. Unlike an 1176, which catches peaks with a vice grip, the CLA-2A uses a combination of a T4 cell (an electro-luminescent panel) and a photoresistor to react to sound.

The "Compress" mode (approx. 3:1 ratio) is standard for most tracks. Switching to "Limiter" increases the ratio significantly, which is great for pins-and-needles sustain on instruments like electric guitar solos. The High-Frequency (HiFreq) Screw:

VU Meter: Can be toggled to show Input, Output, or Gain Reduction (the most common setting).
