About Warm Audio WA76-A

Timeless Compression With A Vintage Voice
The WA76-A faithfully recreates one of the fastest and most powerful studio compressors of all time known for ultra-responsive dynamic control with true analog grit, now with additional modern recording features. Known for use on vocals, drums, guitar, bass, and anything in the studio requiring tight dynamics, the vintage "Blue Stripe" 76 compressors are known for their versatility, speed, and harmonic analog tonality added to recordings. Just like the originals, the WA76-A deliver that classic performance that can be heard on legendary recordings by artists like Led Zeppelin, The Beatles, Chris Stapleton, 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-A achieves authentic "Blue Stripe" compression, known for fast compression while adding more harmonic distortion for unmistakable analog character. Easily the most feature-rich 76-style compressor on the market, WA76-A has added a dry/wet knob for parallel compression, two versions of active bypass for imparting analog color, and selectable input impedance to work with modern recording interface outputs. The single-channel WA76-A has additional sidechain flexibility allowing either key inputs to be inserted or EQs for de-essing, as well as stereo linking.

Applications

Vintage-Voiced Vocals
Control any vocal with the fastest analog compression that won't squash your tone and vibe.

Instant Rock N' Roll Drums
Smash drum busses and room mics. Instantly blend in parallel compression for the ultimate rock and punchy drum sound.

Guitar Control With Grit
Grab hold of dynamically diverse guitar parts and get both electrics and acoustics to sit just right in a dense mix with added analog color.

Add Analog Vibe To Any Mix
Apply vintage-voiced dynamic control without compromising analog tone.

Key Features
Building off of the lauded fame of vintage Blue Stripe compressors, the WA76-A 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 dialing the dry signal alongside the compressed (wet) tone. The SC HPF knob engages a variable sidechain high pass filter with a range of 30-300Hz.

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

WA76-A has two stereo linking jacks to link up to 10 WA76-A compressors for surround/immersive compression. External sidechain inputs and outputs are added to insert key inputs to achieve "ducking" or adding an EQ on the input and output for analog de-essing in real time.
