Warm Audio WA76-D2 – Dual-Channel Class-A FET Compressor Inspired by the Legendary 1176 Rev D

The Warm Audio WA76-D2 is a premium, dual-channel, fully analog FET compressor built to deliver the unmistakable tone and dynamic control of the iconic UREI 1176 Rev D. Designed for modern studios that demand both sonic character and versatile functionality, WA76-D2 offers independent control for each channel, true stereo operation, and features that make it a true workhorse for tracking, mixing, and mastering.

Analog Architecture at Its Finest

Each channel in the WA76-D2 features a 100% discrete, Class-A signal path using premium CineMag transformers (O-12 input, 5002 output). With a switchable input impedance (600Ω / 10kΩ), the unit matches a wide range of modern audio interfaces and preamps. The compressor delivers a wide frequency response (20 Hz – 20 kHz), with attack times from 20 µs to 800 µs and release times from 50 ms to 1.1 s. A maximum gain of 53 dB, ultra-low distortion (THD+N: –67 dB at –6 dBu), and a signal-to-noise ratio of 92 dB ensure pristine audio performance.

Vintage Tone Meets Modern Flexibility

WA76-D2 is more than a vintage clone – it offers modern functionality with creative possibilities. Each channel features an adjustable high-pass sidechain filter (30–300 Hz, 12 dB/octave), independent dry/wet mix control for seamless parallel compression, and an iconic All-Buttons-In mode for aggressive limiting and creative saturation. The illuminated VU meters can display gain reduction or output levels (+4 dB / +8 dB), or be turned off entirely. The unit supports three stereo operating modes: Stereo Linked, Primary/Secondary, and Dual Mono.

Applications – Studio Power and Precision

• Vocals + Instrument Tracking – Compress two mono sources independently.
• Stereo Drum Bus – Use Dual Mono or Linked mode to retain natural imaging.
• Mix Bus Glue – Add analog depth and punch to full stereo mixes.
• Mastering – Subtle dynamic control with vintage sonic character.
