The Warm Audio WA-2A Tube Opto Compressor faithfully recreates the iconic Teletronix LA-2A Leveling Amplifier in a rugged 2RU chassis. With an all-tube, completely discrete signal path and custom transformers, the WA-2A delivers the warm, smooth compression that has made the LA-2A a studio staple for decades.

All-Tube Design Provides Classic Tone

At the heart of the WA-2A are four premium vacuum tubes and an all-tube, fully discrete circuit design with no integrated circuits. This all-tube design, combined with custom Cinemag input and output transformers, gives the WA-2A a warm, musical sound with rich harmonics—the hallmark of sought-after vintage tube gear.

Legendary Optical Cell Handles Signals Gracefully

The WA-2A utilizes a genuine Kenetek opto-cell, considered by many audio engineers to be the finest optical attenuator available. This opto-cell, combined with carefully selected components and an intuitive control set, allows the WA-2A to gracefully handle vocals, bass, drums, and a wide range of other signals with a smooth, natural compression.

Intuitive Controls Make Dialing In Your Sound Easy

With just a few, simple controls, the WA-2A makes achieving a perfect sound easy. The Peak Reduction control allows you to set the amount of gain reduction, from a gentle leveling to more aggressive compression. The Output Gain control then allows you to adjust the output level to match the bypassed signal, enabling easy A/B comparisons.

Rugged Design Delivers Road-Worthy Performance

The WA-2A's rugged, hand-wired design is built to exacting standards in Austin, Texas. A heavy-duty steel chassis and high-quality components ensure years of reliable performance.
