Warm Audio WA-2A: Give your Mix the “Golden” Analog Edge
If there is one compressor that can be found in almost every top studio in the world, it is the LA-2A. The Warm Audio WA-2A brings this legendary sound to your rack. This compressor is known for its ability to equalize signals without sounding audibly compressed. The result is an organic, smooth sound that digital plug-ins simply cannot match.
No Compromise on Components
Warm Audio understands that the magic of an optical compressor hinges on the quality of its components. That’s why the WA-2A is built from the very best components:
Kenetek Opto-Attenuator: The heart of the unit. This optical cell responds to incoming sound like the original, providing the distinctive “multi-stage” release so beloved on vocals.
CineMag USA Transformers: Custom-wound input and output transformers that provide wide frequency response and that typical analog depth.
Four-Tube Signal Path: The WA-2A uses two 12AX7s, one 12BH7 and one 6P1 tube to amplify the signal and add that classic tube saturation.
The Ultimate Tool for Vocals and Bass
The WA-2A is engineers’ favorite for sources that benefit from a gentle but effective approach.
Vocals: Makes voices bigger, warmer and makes them perfectly “stuck” in the mix.
Bass Guitar: Gives bass parts a solid foundation and consistent dynamics without losing the attack.
Guitars & Pads: Adds a layer of analog “glue” that gives instruments more character.
Ease of Use and Vintage Workflow
With only two main buttons – Peak Reduction and Gain – the WA-2A forces you to trust your ears. It’s an intuitive way of working where you find the “sweet spot” within seconds. In addition, the unit features a Pre-Emphasis control on the back that lets you adjust the sensitivity to high frequencies, ideal for de-essing vocals during compression.
