Warm Audio WA76-A

The Warm Audio WA76-A is a faithful reproduction of the legendary FET transistors compressor of the type Blue Stripe, known for its ultra-fast attack speed, its compression power and its warm analog signature. It is a 100% analog mono-channel compressor that combines a respected vintage design and modern additions designed for recording. Ideal for voice, drums, bass, guitar or any instrument requiring tight dynamic control, the WA76-A provides a analog grain pronounced and one extremely reactive dynamic control, who have made his reputation on countless classics.

The WA76-A relies on high-end components to guarantee a sound authenticity without compromise. It includes O-12 input and output transformers 5002 made in the United States by CineMag, meeting the original specifications of the ERUI units. With the addition of dry/Wet control variable high-pass sidechain filter active bypass selector of input impedance and external sidechain connections, the WA76-A is positioned as the most complete FET compressor on the market. It is also possible to bind several units for stereo, surround or immersive applications.

Its 2U rack construction, its symmetrical XLR and TRS jack inputs/outputs, and its all-Buttons-In mode" iconic for aggressive limiter effects, make WA76-A a versatile and reliable studio tool. Its class A discrete transistors gain section, combined with an entirely analog electronic, restores an expressive, dense and energetic sound, while allowing subtle or extreme treatments.
