Warm Audio WA76-D2 – Dual-Channel Clean Gain Discreet FET Compressor

OVERVIEW

The Warm Audio WA76-D2 faithfully recreates the sound and behaviour of one of the most iconic FET compressors ever produced, delivering the ultra-fast transient response, aggressive punch, and rich harmonic character that have shaped countless classic recordings. Inspired by the revered “Revision D” designs, the WA76-D2 combines transparent dynamic control with unmistakable analog colour, making it equally effective on vocals, drums, guitars, bass, room microphones, and stereo bus processing.

“As you’d expect, the WA76‑D2 sounds more elegant in terms of colouration and the gain reduction. Yet, it can go from smooth, gentle vocal or guitar control right up to the sort of grabby, assertive drum effects I associate with FET‑based compressors. If you’re contemplating a WA76 as your go‑to workhorse compressor, this is the flavour you want.” — Sound On Sound

Built around premium CineMag USA transformers wound to vintage specifications, the WA76-D2 captures the authentic tone and response of classic 76-style compression while expanding the feature set for modern recording environments. A dedicated dry/wet mix control allows for instant parallel compression, while selectable input impedance improves compatibility with modern audio interfaces and outboard gear. The addition of a variable sidechain high-pass filter provides greater control over low-frequency compression behaviour, helping mixes retain punch and clarity.

Designed as a versatile dual-channel compressor, the WA76-D2 offers multiple operating modes including stereo, dual-mono, and lead/follow operation for advanced stereo dynamics control. Combined with premium capacitors, metal film resistors, a fully discrete Class-A signal path, and meticulous hand-testing in Austin, Texas, the WA76-D2 delivers classic analog compression with the flexibility and reliability demanded by modern studios.

KEY HIGHLIGHTS

The Timeless Sound Of Tight Compression

The WA76-D2 faithfully recreates one of the fastest and most powerful studio compressors of all time, known for ultra-responsive dynamic control with rich analog tone, now with additional modern recording features. Known for use on vocals, drums, guitar, bass, and anything in the studio requiring tight dynamics, the vintage “Rev D-Style” 76 compressors are known for their versatility, speed, and harmonic analog tone added to recordings. Just like the originals, the WA76-D2 delivers that classic performance that can be heard on legendary recordings by artists like Missy Elliott, Daft Punk, Timbaland, Rick Rubin, Chris Lord-Alge and many more.

True-to-Spec, Plus Bonus Modern Add-Ons

Using premium and custom components like built-to-vintage-spec O-12 (input) and 5002 (output) transformers from CineMag, WA76-D2 achieves authentic “Revision D” compression, known for having a “lower noise” preamp stage with the ability to both compress transparently and also impart unmistakably analog character. Easily the most feature-rich 76-style compressor on the market, WA76-D2 has added a dry/wet knob for parallel compression, two versions of active bypass for imparting analog colour, and selectable input impedance to work with modern recording interface outputs. The WA76-D2 has multiple stereo operating modes that transform the compressor from a stereo unit, dual-mono unit, and lead:follow compressor with the A channel controlling the B channel.

Applications

Vocals — Snappy Vocals:

Control any vocal with the fastest analog compression that won’t diminish the tone of the vocal chain.

Drums — Big Studio Drums:

Squash drum busses and room mics and instantly blend in parallel compression for the ultimate “pro” drum sound.

Guitars — Tight Guitar Control:

Grab hold of dynamically diverse guitar parts and get both electrics and acoustics to sit just right in a dense mix.

Mixing — Rich & Polished:

When needed, apply a final, tight dynamic control to any mix without losing analog mojo or tone.

FEATURES

Summary

Building off the lauded fame of vintage Rev D-style compressors, the WA76-D2 includes all the controls of the original plus critical added features that deliver a complete and professional recording experience.

Use the mix knob to easily achieve analog parallel compression by dialling the dry signal alongside the compressed (wet) tone. The SC HPF knob engages a variable sidechain high-pass filter with a range of 30-300 Hz.

Quickly switch between a traditional 600 Ω impedance ideal for other analog gear to a 10 kΩ impedance that better matches modern audio interface outputs.

The WA76-D2 is a dual-channel unit and has three distinct two-channel operating modes. Stereo mode allows for even compression in the sidechain, focusing on the fastest attack or slowest release. A>AB mode allows the left channel to control the attack/release of the right channel. Sidechains in A>AB mode are still linked as in stereo mode. In A|B mode, the WA76-D2 operates as a dual-mono compressor.
