Warm Audio WA76 Discrete FET Compressor

FET compressor capable reproducing the classic 76-style effect known as ‘All Buttons In’ mode producing a more audible overdrive on the signal
MFR# WA76

Product Description

The Warm Audio 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 classic '76 was a major breakthrough in limiter technology, and used on hundreds of hit records since its inception. Engineers have craved the ultra-fast attack time and trademark sound of the '76 for decades, and now it is finally affordable!

All Buttons In

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’. Originally an accident due to the mechanical nature of the interconnected latching switches, this mode is reproduced by pushing in all four ratio buttons simultaneously and getting them to latch. This can take a bit of practice. 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.

Premium Components

Warm have faithfully reproduced the circuitry of the revision D, generally considered one of the best and most popular among the different versions made over the years. They have used all discrete, through-hole components, high quality CineMag input and output transformers, and Class A circuit that stays true to the legacy design.

I love this thing! I use it on my analogue front end for vocals. Whether I squash the vocal or just apply lightly for gentle dynamics control, it still sounds natural and musical. Very pleased with my purchase. The guys down at VK were really cool too :-)

We have 4 of these in our audiobooks studios. We pair them with Neumans and it’s really warm and transparent. Great value for the price.

Loving the harmonics the all-buttons-in mode gives my vocals!

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
