Warm Audio WA76-D – Single-Channel Vintage-Style FET Compressor

The WA76-D from Warm Audio brings the fast, punchy character of classic Revision D FET compressors into a modern, studio-ready design.

Key Features

• Discrete analog FET circuit with CineMag transformers: Recreates the harmonic richness and ultra-fast response of vintage units.
• Selectable input impedance: Switch between 600 Ω and 10 kΩ to suit both vintage hardware and modern audio interfaces.
• Dry/Wet mix control: Perfect for parallel compression techniques that add punch without sacrificing dynamics.
• Side-chain high-pass filter: Adjustable from 30–300 Hz to prevent low frequencies from triggering excessive compression.
• Classic FET behavior and All-Buttons-In mode: Ultra-fast attack and release times allow everything from subtle control to aggressive character shaping.

Customer Benefits

The WA76-D gives engineers and producers an authentic, musical compressor that excels on both individual tracks and mix elements.
