Packed With Features
The WA-412 has all of the features one would expect from this style of preamp... and more. Output Trim is available on every channel for precise control and creative gain staging. A Tone switch (transformer input impedance) is also available on each channel, which allows you to choose between a warm and punchy classic console tone or go for a more open & neutral sound.
Each channel utilizes a fully discrete socketed 6-pin 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.
Warm Audio is proud to be using input and output transformers that are made in the USA by a high-end transformer manufacturer, Altran. We 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 smooth BIG 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 vintage console magic to your signal.
