The Warm Audio WA76-A/A2 Channel Vintage-Voiced FET Compressor captures the unmistakable punch and character of one of the most legendary compressors ever made — the original “Blue Stripe” A-Rev ’76 limiter. Known for its aggressive attack, smooth release, and unmistakable analog saturation, this faithful re-creation brings that studio-class sound into the modern era with added flexibility and control.Powered by a 100% analog discrete circuit path and CineMag USA transformers, the WA76-A/A2 delivers stunning clarity and warmth across the frequency spectrum. Its dual-channel configuration allows for stereo or dual mono operation, making it ideal for vocals, drum buses, guitars, and mix bus compression. With variable attack and release, engineers can shape transient detail precisely — from subtle glue to all-out punch.Modern upgrades include a variable sidechain high-pass filter, allowing you to control how bass frequencies influence compression, and a blend control for effortless parallel processing. Additionally, the switchable impedance ensures compatibility across modern and vintage recording systems, while the true bypass and VU metering simplify professional operation.Built to Warm Audio’s demanding standards, each unit is hand-assembled and tested in Austin, Texas, ensuring reliability and sonic authenticity. Whether you’re chasing vintage warmth or adding analog polish to your mix bus, the Warm Audio WA76-A/A2 delivers legendary compression tone with modern precision and studio-grade versatility.

• Single-Channel Vintage FET Compression Design: The WA76-A/A2 authentically recreates the sound and response of the iconic “Blue Stripe” A-Rev ’76 limiter, delivering warm, punchy, and transparent compression. Its channel architecture and true analog circuitry make it perfect for tracking, mixing, or mastering vocals, drums, bass, and full stereo mixes.
• Premium CineMag Transformers For Analog Warmth: Equipped with custom, large-core CineMag USA input and output transformers, the WA76-A/A2 provides lush harmonic coloration and depth. These transformers, combined with a fully discrete Class A circuit, deliver rich analog tone and smooth compression that enhances the character of any sound source.
• Flexible Control And Modern Features: Featuring vintage-style attack and release controls with precise variable timing, the WA76-A/A2 offers unparalleled control over transient response. The addition of a dry/wet blend knob enables easy parallel compression, while the sidechain high-pass filter (30Hz–300Hz) prevents low-end energy from over-triggering the compressor.
• Selectable Impedance And Parallel Operation: The WA76-A/A2’s selectable input impedance (600Ω or 10kΩ) ensures perfect compatibility with vintage gear and modern interfaces alike. An active bypass mode allows it to function as a line amplifier, while true bypass switching ensures instant A/B comparison for seamless workflow in professional or project studios.
• Handcrafted Quality With Pro Studio Build: Handwired and inspected in Austin, Texas, the WA76-A/A2 is built with premium metal film resistors, ceramic capacitors, and through-hole components for durability and sonic excellence. Its sturdy 2U rackmount chassis, VU metering, and 100–230V internal power supply make it a reliable centerpiece for any recording setup.
