Warm Audio - WA-412
Four-Channel American Mic Pre
recreating a legendThe WA-412 features 4 channels of classic American console preamps in a discrete 1RU design. This type of preamp is often named "the sound of Rock n' Roll" for its huge punchy low end and smooth open top end. The price/performance ratio of the WA-412 is almost unexplainable to the experienced studio engineer who has potentially paid much more for preamps of this style throughout their career. With fully discrete socketed 6-pin opamps and custom wound Altran USA input and output transformers, the WA-412 is nothing short of world-class. If you are looking for multiple channels of world class tone in an affordable package, the WA-412 will certainly suffice.
Amazing Features
• 4 channel microphone preamplifier and instrument DI
• Fully discrete, transformer coupled, through-hole component topology
• X520 discrete op-amp in every channel, socketed for convenience
• Altran USA custom wound, premium input and output transformers
• -20dB pads for both mic and instrument DI inputs
Inspiration Behind The WA-412
Bryce Young (founder) says...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.
Because of this so many of the sources were recorded through poor-quality mic preamps. 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 work-horse in many professional and home studios.
Packed With Features
The WA-412 has all of the features you would expect from this style of preamp and more. Output Trim is found on every channel for accurate control and creative gain staging. A Tone switch (transformer input impedance) is also available on each channel, which enables you to choose between a warm and punchy classic console tone, or go for a more open & neutral sound.
Quality ComponentsEach channel comes with a fully discrete socketed 6-pin opamp that can be swapped with other opamps. Discrete opamp circuitry is renowned for its high headroom and low distortion characteristics and has much to do with the coveted sound of these classic console preamps.
High-End TransformersProudly featuring input and output transformers that are made in the USA by high-end transformer manufacturer, Altran. Warm Audio worked closely with Altran to create unique transformers that extend the low frequency response of these classic preamps. The transformers also use a vintage winding technique that produces a very distinct and smooth character.
