WARM Audio WA-76 compressor

The WA76 Discrete Compressor is a modern reproduction of the Classic ’76 Revision D. The WA76 has a fully discrete signal path and uses the original Reichenbach Engineering’s (now CineMag) transformer design.
The WA76 can reproduce the classic effect known as ‘All Buttons In’ mode, sometimes also referred to as ‘British Mode’ or the ‘Four Button Trick’. The resulting compression curve is aggressive and unmistakably unique, and can be heard on the drum tracks of many classic recordings.
All-buttons-in compression is typically characterized by having a very aggressive compression ratio, attack and release curves that are more drastic plateaus opposed to gentler slopes, and more audible distortion or ‘overdrive’ on the signal. Initial transients are more likely to come through loudly, followed by heavy compression curve sometimes described as having a ‘sucking’ effect as the compressor releases. Because this mode is considered a design accident, faithfully maintained; it is normal for the meter function to ‘peg out’ and cease providing accurate metering.
