The WA76-D2 accurately reproduces 2 channels of one of the fastest and most loved studio compressors of all time, known for its generous headroom, ultra-fast dynamic control, and rich analog tone. Using premium and custom components like O-12 (input) and 5002 (output) transformers from CineMag, WA76-D2 achieves authentic 76 rev-D style compression, known for “low noise” preamp stage with unmistakably analog character. Added modern controls to achieve parallel compression, active & true-bypass, and variable sidechain filtering flexibility make WA76-D2 an ideal choice for modern recording workflows that require vintage tone shaping. WA76-D2 recreates the legendary tone & control of the vintage 76-style compression used in studios by artists like Missy Elliot, Timbaland, Van Halen, Rick Rubin, Daft Punk, and many more.

Features:

• Building off of the lauded fame of vintage Rev D-style compressors, the WA76-D/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 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 600Ω impedance ideal for other analog gear to a 10kΩ impedance that better matches modern audio interface outputs.
• SINGLE CHANNEL ONLY: WA76-D has two stereo linking jacks to link up to 10 WA76-D compressors for surround/immersive compression. External sidechain inputs and outputs are added to insert key inputs to achieve “ducking” or add an EQ on the input and output for analog de-essing in real time.
• 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.
