Warm Audio WA76-A – Single-Channel Vintage-Voiced Discrete FET Compressor
The WA76-A from Warm Audio brings the punch, speed and harmonic richness of the legendary “Blue Stripe” 76-style studio compressor into a modern, single-channel design. It’s built for professional tracking, mixing and mastering settings where vintage tone and fast dynamics control matter most—available through Soundium.
Key Features
-
100% discrete analog FET circuit with CineMag O-12 (input) and 5002 (output) transformers: Captures the authentic character and harmonic grit of the original studio classics.
-
Selectable input impedance (600 Ω or 10 kΩ): Ensures compatibility with both vintage high-gain gear and modern audio interfaces.
-
Dry/Wet mix control for parallel compression: Blend compressed and clean signal to preserve dynamics while adding punch.
-
Side-chain high-pass filter (30–300 Hz): Prevents low frequencies from over-triggering compression, ideal for bass, drum rooms and full mixes.
-
Stereo link and external side-chain access: While the unit is single-channel, it supports linking multiple WA76-A units for stereo or surround processing.
-
Classic FET attack/release with “All-Buttons-In” mode: Attack range from 20 µs to 0.8 ms and release from 50 ms to approx. 1.1 s, allowing everything from subtle shaping to aggressive limiting.
Customer Benefits
The WA76-A provides the signature speed and tonal character that has defined countless recordings, with added controls for today’s workflows. Whether you’re compressing vocals, drums, guitars, or using it on the stereo bus, you’ll appreciate the analog fullness, controlled dynamics and flexible routing. The impedance switch, mix knob and side-chain filter make integration into modern setups straightforward, while the true-to-vintage design ensures studio-grade tone—with Soundium quality.
