Manufacturer's Description from Warm Audio

The WA-412 provides 4 channels of classic American console preamps in a sleek 1RU design. This style of preamp is often referred to as "the sound of Rock n' Roll" for its BIG punchy low end and smooth open top end. The price/performance ratio of the WA-412 is almost unfathomable to the experienced studio engineer who has possibly paid much more for preamps of this style during their career. Featuring fully discrete-socketed 6-pin op-amps and custom wound Altran USA input and output transformers, the WA-412 leaves nothing to be desired. If you are looking for multiple channels of world-class tone in an affordable package, the WA-412 might be the right choice for you.

The inspiration behind the WA-412.

When I first started holding regular studio sessions years ago I always desired to have more channels of high-end mic pre's. I could only afford to have one or two in my studio at a time, which was never enough to record a full band or drummer. I knew very well that if signals were not recorded well "on the way in" they wouldn't be salvageable later, but my budget-constrained me, so many of the sources were recorded through poor-quality mic pre's.  If the WA-412 was available back then I likely wouldn't have had to settle for poor, low-quality tone. The WA-412 was designed "for the people" (if you will) and we believe it will become a serious workhorse in many professional and home studios. - Bryce Young (founder)

More features.

The WA-412 has all of the features one would expect from this style of preamp... and more. Output Trim has been added to every channel for precise control and creative gain structuring. We also added a Tone switch (transformer input impedance) to each channel, which allows you to choose the warm and punchy classic console tone, or a more open & neutral sound.

Better components.

Each channel utilizes a fully discrete-socketed opamp that can be swapped with other opamps. Discrete opamp circuitry is known for its high headroom and low distortion characteristics and has much to do with the coveted sound of these classic console preamps.  

We are proud to be using input and output transformers that are made in the USA by high-end transformer manufacturer, Altran. We worked closely with Altran to create unique transformers that extend the low-frequency response of the design. The transformers also use a vintage winding technique that produces a very distinct smooth & open character.

Carefully choosing the WA-412 components has resulted in an amazing four channel ‘workhorse’ preamp/DI that performs at the highest levels, while still adding a touch of vintage console magic to your signal.

About Manufacturer

Warm Audio's goal is to put high-end gear in the hands of the world’s greatest artists, talent deserves to be properly expressed. Many great musicians are never heard in the right light due to budget restrictions, Warm Audio hopes to change this by bringing fully professional designs to all studios at affordable prices. Don't let our price tags fool you, all of our products have completely discrete signal paths and feature custom USA made CineMag transformers that are found in only the best designs in pro audio.

I am asked often how Warm Audio is able to produce such high quality gear at affordable prices, many assume corners must be cut somewhere.  My answer to this question continues to be "NO".  Warm Audio stays true to original discrete schematics and does this without cheapening components such as our continued use of world class Reichenbach/CineMag transformers.
