Warm Audio WA76-A2 Dual Channel Vintage-Voiced Discrete FET Compressor

1. Classic Studio Compression With True Analog Grit: The WA76-A is a faithful recreation of the vintage 76 “blue stripe”-style FET studio compressor with added features to meet modern recording workflows. Recreating the lauded original vintage “Blue Stripe” version of the 76 compressor known for its extra “grabby” fast attack and vintage analog grit, the WA76-A offers the ideal blend of vintage circuitry and modern controls to deliver ultimate flexibility without sacrificing vintage analog character. 

2. Critical Classic Controls + Bonus Modern Add-Ons: WA76-A delivers vintage circuit design and all of the traditional 76-style compression controls; attack, release, ratio, input, output, and meter display. In addition to the classic controls expected on a 76-style compressor, WA76-A has added stereo linking, dry/wet mix for parallel compression, external sidechain, selectable input impedance, active & true bypass, and variable sidechain high-pass filter to tackle unruly bass that dominates the compressor’s attention.

3. Custom CineMag Transformers: Just like in the vintage 76-style compressors from revision “A” to D”, the WA76-A uses custom large-core, CineMag input & output transformers. The transformers inside the WA76-A use the exact same spec data and materials used by Reichenbach Engineering in the original vintage designs known for delivering vintage analog grit to any signal chain. 

4. Premium Components & Accurate Blue Stripe-Style Circuitry: WA76-A uses premium poly film capacitors, carbon resistors, and a vintage-voiced preamp stage. These key components complete a circuit that cuts no corners in delivering an authentic vintage 76-style “blue stripe”-style compression experience. 

5. Hand-Tested In Austin, TX: Like all Warm Audio gear, WA76-A is meticulously hand-tested and inspected by trained technicians with a passion for making music in Austin, TX USA.
