Warm Audio WA76-D – Premium Analog FET Compressor Inspired by the Iconic 1176 Rev D

The Warm Audio WA76-D is a fully analog, single-channel FET compressor that faithfully recreates the legendary UREI 1176 Revision D. Revered by engineers for its lightning-fast response and rich harmonic saturation, the 1176 has been a studio staple for decades. WA76-D combines this iconic vintage tone with modern enhancements, making it an indispensable tool for today’s recording and mixing environments.

Key Sound and Technical Features

At the heart of WA76-D lies a discrete, Class-A signal path designed for optimal sonic performance. Equipped with high-quality CineMag transformers (O-12 on input, 5002 on output), the unit delivers clear, punchy, and harmonically rich audio. Attack times range from 20 µs to 800 µs, while release times vary from 50 ms to 1.1 seconds. With an impressive SNR of 92 dB (A-weighted) and ultra-low THD+N of –67 dB at –6 dBu, the WA76-D offers pristine sound for critical studio applications.

Modern Features with a Vintage Soul

The WA76-D expands beyond a simple recreation by adding modern workflow enhancements. A fully adjustable sidechain high-pass filter (30–300 Hz, 12 dB/octave) improves dynamic control for bass-heavy sources. The dry/wet mix control enables true parallel compression without the need for additional routing. You also get both active bypass (for use as a clean line amp) and true bypass for fast A/B comparisons. And yes, the iconic "All-Buttons-In" mode is present for that aggressive limiting sound cherished in rock, hip-hop, and pop production.

Applications – Professional Flexibility

Whether you're tracking, mixing, or mastering, the WA76-D delivers unmistakable sonic control and color. Perfect for:

• Vocals – enhanced presence and definition
• Drums – superior transient shaping and punch
• Electric/Bass guitars – tonal clarity and control
• Keyboards/Synths – smooth dynamics and added warmth
• Mix bus – subtle glue and vintage vibe for full mixes
