Warm Audio WA76-D2 — Dual-Channel Rev D Style FET Compressor
The Warm Audio WA76-D2 is a fully analog dual-channel FET compressor, faithfully recreating the legendary Rev D compression style while adding modern flexibility for professional recording, mixing, and mastering applications.
It delivers the classic fast attack, musical response, and rich analog character that has defined countless iconic recordings.
Dual-Channel Flexibility
The WA76-D2 features a true dual-channel design with three operating modes:
- Stereo Linked — both channels operate together for stereo processing
- A>AB (Primary/Secondary) — channel A controls attack/release of channel B
- A|B (Dual Mono) — two fully independent compressors
This flexibility makes it ideal for both stereo and dual-mono applications.
